Rio Karasuki/Relationships

Celia Claire
Celia is very important to Rio and is probably the only one who understands him the most, as she spent a long time with him.

Rio first met Celia at the age of 7 in the slums, just after he got his memories of Amakawa Haruto. Celia found his polite speech and demeanor impressive for his age. After Rio’s enrollment in the Royal Academy, she was the only one who talked with him and they grew close enough to have tea parties together in Celia’s lab. On the first day of school, she taught him how to read numbers after knowing that he could not read nor write them. On the other hand, Rio would help to clean up her laboratory, prepare tea and snacks for their tea parties, and organize her research material (although most of it was because he couldn't tolerate Celia's messy lab). Initially, Celia and Rio had a teacher-student relationship but it changes to that of close friends when Rio said he will be fine with not making any friends as long as Celia is with him, a fact which embarrasses her at first but she states that she is fine with being Rio’s friend because from infancy, she had been pushed to move forward, much to the envy of her surrounding peers and she had no intimate friends close to her, so having someone to talk to without reservation was both new and precious to her. The time she spent with Rio every day was fun, and she had been overjoyed to hear that Rio considered her a friend.

During the five years at the academy, she subconsciously starts developing romantic feelings towards him which are implied when she broke down and started crying after Rio ran away from the kingdom or when she was extremely shaken after seeing Rio getting a love letter from a female student but she thinks the reason she was shaken was because of her protective maternal feelings towards him since he was at the very bottom of the chain at the academy.

Although Celia always regretted not being able to do much for Rio since she was powerless, her keeping Rio company through his isolated period in the academy was so effective that Rio does not consider his time at the academy to be sad and due to this Rio considers Celia someone who is very dear and important to him. (Volume 1)

Celia finally realizes her feelings for Rio were romantic 4 years later when she had to politically marry Charles Arbor (becoming his seventh wife) as a sacrifice to clear her family of suspicions towards helping Duke Huguenot in taking Flora out of the capital. During this period, the only thing that gave her comfort was Rio’s letters and she finally realized that the reason she couldn’t get Rio out of her mind was that she liked him and wants to see him one more time before being married.

When Rio secretly visits Beltrum 4 years later, he regrets that he wasn’t there when Celia was forced to get the short stack of the political stuff happening in the kingdom and wants to know her true feelings regarding her marriage after sneaking into her heavily guarded room. Celia is really happy to see Rio and immediately hugs him but when Rio asks her if she is really fine with what is going to happen several times after Celia hesitantly kept saying that she is the one who agreed to her marriage, she asks Rio if he is willing to take her away somewhere and live with her for rest of her life to which Rio responds that if she truly desires that then he will take her away. Celia is really happy to hear that but knows that doing so will put Rio in an extremely dangerous position and she does not want him to suffer more because he had already suffered so much in the academy so she says that she was just kidding and knowing that Rio was willing to go that far was enough for her since she cannot go with Rio as she would have to abandon her family and remain unmarried for the rest of her life. Despite Rio’s insistence she tells Rio to go and not attend her parade to which Rio reluctantly accepts. After gathering more information about the marriage and finding out that Celia is being used as a sacrifice, Rio interrupts the parade, keeping his face hidden and holds Celia hostage in front of everyone in the kingdom and once more asks Celia about her true feelings (telepathically), stating that she is very important to him, and he does not want to see her dignity being trampled as he just sits around. He asks Celia if she can truly say she will be happy in the marriage to which she falters and after Rio convinces her that nothing bad will happen to her and her family if she is kidnapped from her marriage in front of everyone, she asks Rio to take her away to which he happily obliges. (Volume 5)

Afterward, Rio takes her in his care, during which her feelings for him keep growing stronger to the point where she deeply falls in love with him, getting jealous when she found out Aishia and Rio slept in the same bed. Aishia supports Celia and tells her to sleep with them so all 3 can just sleep together to which she agrees but says that she is just doing to supervise Rio and Aishia. Rio was surprised when Celia bluntly stated that she trusts Rio and believes he won’t lie to her when he was going to reveal his reincarnation to her, a fact which makes him feel happy. Aisha was also happy at the fact that Celia had accepted all sides of Rio. (Volume 6)

Celia doesn’t want to be a burden to Rio as seen when she tells Rio to prioritize his feelings and chase after Lucius when he was hesitating because it would mean leaving Celia in danger and Aishia supports her by saying she will protect Celia and Rio should do what he wants to do. (Volume 7)

Although she felt slightly conflicted by the fact that most of Rio’s friends were cute girls, (Sara, Alma, Orphia, Miharu, etc.) she felt very happy that Rio was surrounded by such warm people and friends unlike back in the academy. (Volume 9)

After the banquet arc, when Rio says he will help Celia get her position as a noble back and reunite her with his family, Celia tells Rio to treasure and take care of Miharu since she is his childhood friend from his previous life and his childhood in this life was very painful since he did not have anyone to call his childhood friend to which Rio says, “It’s true that Miharu is important to me. But you’re important too, Professor Celia. If Amakawa Haruto’s childhood friend is Miharu, then Rio’s childhood friend is Celia Claire. That’s what I believe, at least”, hinting that Rio might also have feelings for Celia as Amakawa Haruto was in love with Miharu. Rio also says he stopped her wedding because he wanted her to be happy and nothing has changed from then and all she needs to do is take his hand as she did during her wedding to which Celia is so happy that she starts crying. (Volume 11)

Celia is currently going to the Resistance along with Christina and her royal guard. (Volume 12)

Now she is with him as his attendant.

Flora Beltram
Due to his history in the Beltrum kingdom (falsely charged) Rio is extremely wary of Flora. At the same time, he has no grudge against Flora as he knows she did not frame him in the outdoor drill, he hoped to never meet with her (volume 7). Flora is the first one from the Beltrum kingdom to suspect Rio's new disguise. During his days at the academy, Flora was sad seeing the treatment Rio received from the nobles and always wanted to talk to him. Flora has great admiration for Rio.

Christina Beltrum
Rio first met Christina in the slums as she was searching for her abducted Flora. She did not know how to interact with common people and slapped him because she believed he kidnapped her sister. During their time at the academy, she avoided talking to him and didn't oppose framing him for the outdoor drill incident. Years later, she meets Rio at the banquet in the Galarc kingdom presenting the hero Satsuki, and despite being watched by the Arbor faction, secretly thanked him for saving her sister in Amande. Rio meets with her again as he accompanies Celia to Creia. Christina escaped from the castle from the Arbor faction and asked him to escort her to Rodania. Seeing the trust between Rio and Celia, she suspects Amakawa Haruto to be Rio, a suspicion confirmed by Reiss later.

Gigi
The relationship with Rio is quite close and also friendly. Gigi often talks to Rio, she also gives money to Rio for food in the morning, Gigi always watches Rio like this. Unfortunately, Gigi had been killed by a masked man, her corpse in front of Rio made Rio want to vomit.

Zen
Rio's father passed away shortly after his birth. He was an adventurer and a former royal guard of the Karasuki Kingdom. Five or six years before Rio's birth, the Karasuki Kingdom had already been at war with the Rokuren Kingdom for a while, making life in Zen's village and others throughout the kingdom, challenging. To reduce the number of mouths to feed in his house, Zen left his village.

After leaving, Zen joined the kingdom's army. Once there, his talent for spirit arts and military arts, respectively, caught Gouki's eye; thanks to that, Zen quickly distinguished himself. It didn't take long for him to be known as a war hero in the kingdom that the king decided to give Zen the title, "Samurai."

According to tradition, those named as samurai duel after a ceremony, with one of their seniors -- who in Zen's case was Gouki. Gouki at the time was already hailed as the strongest in the kingdom. In the end, Zen lost against Gouki by a thin margin, but Gouki, impressed with Zen's skills, began to strongly recommend him as a royal guard, earning him a spot as one of Ayame's bodyguards with Gouki and Kayoko.

Ayame grew quite taken to Zen in no time because for her, he was the embodiment of everything she always wished for: the world outside the castle. Ayame, with Gouki and Kayoko, would teach Zen the manners and etiquette necessary for a royal guard, and later by Ayame's insistence (without paying mind to Zen's reluctance), they would visit Zen's village in secret several times.

Months later, the Rokuren Kingdom would propose a ceasefire treaty to the Karasuki Kingdom and send its prince as an ambassador. The night when everyone was celebrating the long-lasting war coming to an end, that same prince would order Ayame's kidnapping; Zen detained the kidnapper, but they committed suicide just after. The Rokuren prince, using this incident to his ends, declared it a personal attack against him and proposed Zen's execution and marriage to Ayame as conditions for continuing the ceasefire.

The king pretended to agree, while at the same time commanding Zen to leave the country with his daughter, buying them time making preparations for winning the war via a surprise attack. It succeeded at the cost of Zen and Ayame losing their place in the Yagumo region, with a bounty on their heads for desertion and kidnapping of royalty.

After arriving at the Strahl region, Zen and Ayame began working as adventurers, traveling to different places. After Ayame became pregnant with Rio, they settled in Beltrum's capital, where they bought a cheap house in a district relatively good, outside the castle walls. In the middle of adapting to the city, Lucius approached them pretending to be friendly, and when Rio was still a newborn, killed Zen, making it look as he messed up on the job. Fortunately, Zen earned enough money for Ayame and Rio to get by for years without working, but five years later Lucius would finally reveal his true colors, and after raping and killing Ayame in front of Rio, stole everything from them and abandoned Rio in the slums.

Ayame Karasuki
She was Rio's mother -- a princess from the Karasuki Kingdom in the Yagumo region -- after Zen became her bodyguard she quickly warmed up to him, as he would often tell her stories of the outside world. She, along with Gouki and Kayoko, would silence those opposed to Zen being her bodyguard and teach him all the necessary manners and etiquette for a royal guard. Additionally, she would often ask Zen to be taken outside the castle to places like his village, to the begrudging of the latter. Her father realized their mutual feelings long ago, but getting them married wasn't possible because the nobles from other factions wouldn't allow Ayame to get married with an upstart like Zen despite being famous as a war hero throughout the kingdom, and Ayame herself having a low position on the succession list.

The night that the Karasuki Kingdom was celebrating the end of the war against the Rokuren Kingdom, the prince of the said kingdom was staying at Karasuki's castle as an ambassador. He would soon order her kidnapping, Zen apprehended the kidnapper while she was sleeping but the culprit committed suicide shortly after that. The prince from the Rokuren kingdom would make it look like his vassal's death was a personal attack against him and would demand her to become his wife and Zen's execution as a condition for not breaking the ceasefire with his kingdom.

Ayame's father would pretend to accept that demand while ordering Ayame and Zen to escape from Yagumo together while he was making preparations for winning the war to come while earning them time with his charade. After fleeing to the Strahl region Zen and Ayame would travel from place to place working as adventurers until they finally settled in Beltrum's capital when she got pregnant with Rio.

Once in Beltrum's capital they bought a cheap house in a district relatively good outside of the castle walls and began to live there. When they were still adapting to their new land Lucius approached Zen and began to take on adventurers' requests with him in Ayame's place as she was taking care of Rio, when Rio was still a newborn Lucius killed Zen while making it look like he messed up on the job.

Fortunately for Ayame Zen had already earned enough money for her to not need to work being able to pay for hers and Rio's needs during his childhood, Lucius still acting like a good friend towards her, extended a helping hand during the next five years, then the day came when Lucius finally showed his real colors and assaulted and killed her when she resisted in front of the five-year-old Rio.

Karasuki Homura
The current king of the Karasuki kingdom, Ayame's father and Rio's grandfather, in the past he realized Zen's and Ayame's feelings for each other, and even though he wished to let them get married he wasn't able to because the nobles from other factions wouldn't have seen with good eyes a marriage between a princess-like Ayame and an upstart like Zen, despite her post in the succession list being low, and Zen being famous as hero of the war in the whole kingdom. After the ceasefire incident he ordered Zen and Ayame to escape together while pretending to accept the demand from the Rokuren kingdom's prince of turning them over, then with the time that he gained with his charade, made the preparations for winning the war against the Rokuren kingdom.

Homura's plans succeeded but in exchange Zen and Ayame lost their place in the Yagumo region due to the scheme for defeating the Rokuren kingdom, something that has always weighed in his mind until Rio told him that his parents were able of being happy together and that he never saw something like regret or sadness in Ayame's face.

After hearing of Rio's plans of avenging his parents he was prepared for stopping him if he considered that Rio didn't have what it's necessary for going down that path. Deeming Rio sane and smart enough to not lose himself for the sake of avenging his parents he chose to not stop him and instead tried lending a hand.

He ordered Gouki to have a mock battle with Rio, expecting Rio to be defeated by him and afterward convincing him of living in Gouki's home as his disciple and live there until he gained enough strength for his purpose, something that was supposed to give him more chances of meeting with Rio more often and more easily. Against everyone's expectations, Gouki wasn't able of putting a scratch on Rio, and his plan failed.

In future reunions with Rio, he offered him to take with him on his journey Gouki, Kayoko, Komomo, and a group of ten retainers for helping with his revenge, but Rio refused.

Ruri
She is Zen's older brother's eldest daughter, when she was a child her mother and little brother died from starvation after an epidemic and a bad harvest, at that time her father was already dead too, but the cause was never specified, the most likely being in a war somewhere. Since then, she was raised alone by Yuba, she's equally close to everyone in the village except for Sayo and Shin as they were the ones who spent more time with her in her childhood when they were learning spirit arts together from Yuba and that as fellow orphans they hung out a lot too.

Since seeing Yuba's reaction when Rio said to her his parents' names and later Rio was allowed to stay with them in their house, she suspected that he may be related to Yuba somehow too, but she did the tactful thing and decided to not ask about that until they decided to bring it up themselves. When Rio finally told her that they were cousins she was more surprised about Ayame being a princess than about being related to Rio but was happy about it, nonetheless.

By Yuba's petition, she helped proactively in helping Rio to adapt to the village and to form a favorable relationship with their neighbors. When all the village's girls began to address Rio as Rio-sama, she was the only one that kept treating him normally what made Rio consider her his only important conversation partner. When all the boys got jealous of all the times that Rio and she spent together she never paid it any mind and defended Rio from them.

Latifa
Latifa was ordered to kill Rio and had no other choice due to the pain from the slave collar. However, Rio easily took her down and released her from being a slave. Confused and still unable to believe this, Latifa instinctively followed Rio having no idea where to go. Due to Rio pitying Latifa and her young age he decided to accompany her to Seirei no Tami and part ways then. Throughout their journey, they became close, enough to establish a sibling-like relationship.

Sendou Aki
Haruto's sister, after the divorce she and her mother left the house where they used to live with him and her supposed father and moved to another place. They lived alone for several years until her mother got married again to Takahisa's and Masato's father. Several years later, after her first day at her middle school, when she was going back home with her siblings, Miharu and Satsuki, she got dragged into Satsuki's and Takahisa's hero summoning.

She, Miharu, and Masato appeared on grassland near the border of the Galarc kingdom with the Centostella kingdom, they walked together to a highway, where they were spotted by a slave trader that tried to kidnap them, but they were quickly saved by Rio, her brother Haruto's reincarnation. Rio sheltered the three and explained to them that they were in another world now, and six months later Rio finally found her friend Satsuki and her older brother Takahisa and helped her to reunite with them. After having her trauma of being abandoned by her supposed father and brother by Takahisa she went temporarily mad and agreed to help him kidnap Miharu. Following the kidnapping incident, she was sent to the Centostella kingdom with Takahisa, where Masato is currently watching over her rehabilitation.

Sendou Masato
The second son of the man who got married to Haruto's and Aki's mother after the divorce, Takahisa's little brother, Haruto's and Aki's little step-brother. Due to mentioning Haruto in front of Aki being taboo, he was never told that Haruto was his older step-brother living away with his father. On the first day of his sixth year at the elementary school, he got dragged into Takahisa's and Satsuki's hero summoning.

He suddenly appeared with Miharu and Aki in the middle of grassland near the border between the Galarc kingdom and the Centostella kingdom, the three walked together until they were near a highway where a slave trader spotted and kidnapped them to be rescued a little later by Rio, his older stepbrother Haruto's reincarnation.

After being rescued by Rio he began to treat him as an older brother, he was invited to the rock house where he explains to Miharu, Aki, and him that they are now in another world, since then Rio sheltered the three temporarily.

Sendou Takahisa
The first son of the man who got married to Aki's and Haruto's mother after her divorce, Aki's older step-brother and Masato's older brother. He met Miharu through Aki and fell for her at first sight and went to the same middle school that Miharu and Satsuki, where he became the latter's friend too. Despite liking Miharu he never dared to confess to her due to the fear of what would happen to the group's status quo after he does it, but he would still always act close and familiar with Miharu around other boys for the sake of keeping them away from her. His stickiness made Miharu uncomfortable a lot of times, but because Miharu never dared to point it out due to her shy nature and not wanting to complicate her relationship with Aki she somehow dealt with it and Takahisa never learned of the wrongness of his ways.

When going back home after his first day at high school, he and his senpai Satsuki got summoned to another world as heroes dragging Miharu, Aki, and Masato with them. Takahisa then appeared in the royal castle of the isolationist Centostella kingdom. While in Japan he never knew of his step-brother's existence, when he met his reincarnation Rio he was grateful for his help to his family and reuniting him with them, but at the same time, he felt rivalry towards him because Miharu seemed to prefer him over Takahisa himself. He was so fixated on how big his presence was in his friends' and siblings' hearts that he didn't pay any mind to the fact that he had one more brother and that Rio was his reincarnation. He ended up hating him for getting in the way of his plan for having Miharu for himself.

Aishia
Aishia is Rio's contract spirit as well as a high-rank spirit, of which their existence is incredibly rare. She has been contracted with Rio since the start of the novel, during the time Haruto's memories awakened within Rio. Aishia was the one who taught Rio the spirit arts before he sets foot on Seirei no Tami after he fled from the Strahl region due to being framed for the cliff incident. Before her awakening in her humanoid spirit form, Aishia spent the 3 prelude arcs mostly by sleeping and residing within Rio. Rio would occasionally hear Aishia's voice briefly in a form of inner monologue, where she tries to help and guide him out of his predicament. Aishia eventually manifested herself and wakes up next to Rio on his bed after Rio successfully rescued Miharu, Aki, and Masato from the slave traders.

As Rio's spirit, Aishia knows everything about Rio, including his past life, his dreams, his feelings, and his regret. For Aishia, Rio is her everything and she is willing to do anything for him. Aishia never calls him Rio but Haruto instead, despite Rio's insistence that they are two different people, and he is just Rio with Haruto's memories, but not Haruto's persona. It's been later implied about why Aishia was stubborn to call him Haruto, it was because he refused him being Haruto, she used to call him Haruto to constantly remind him of the fact that no matter what he says and believes he can't change the fact that he was Haruto once he accepts that and moves on Aishia starts calling him Rio. For Aishia, Haruto and Rio are the same.

Ayase Miharu
Ayase Miharu is Amakawa Haruto's (Rio's previous life) first love and childhood friend. Before they separated when they were nine years old, they made a promise to marry each other when they grew up. Due to that promise, both of them worked hard in every aspect to be a better man/woman for the other party. When they reached the age to enter high school, Haruto returned to the city where Miharu was and managed to enter the same school by chance. After discovering her attendance at the same school through the class listing, he went out to search for her. However, upon seeing the seemingly close relationship between Miharu and Takahisa, Haruto ran away and missed the chance to reunite with Miharu as he mistook Miharu and Takahisa's relationship. After a few days of hesitation, Haruto decided to talk to Miharu face-to-face to remove the regret for not facing her. However, that regret couldn't be removed as Miharu went missing (she was transmigrated to another world). Haruto carried this regret till the end of his life when he lost his life during a traffic accident. In volume 4, the reincarnated Haruto, Rio, found Miharu and co. in the forest. Rio was confused about how to interact with her again as his moral values were different from those when he was Amakawa Haruto. He detested the idea of involving Miharu and those he holds dear in his revenge toward Lucius. This stemmed from the fact that he felt guilty of killing people despite it being necessary. Hence, he felt that he is not qualified to be close to her nor is he qualified to attain happiness.

Later, Aishia bestowed a dream upon Miharu, a dream about Haruto after they separated and Rio before they reunited again. This spurred Miharu to approach Rio more aggressively (it is only aggressive when compared to her usual shy/timid personality).

Aishia also warns Miharu that Rio is a kind yet cowardly person as he doesn't want the people, he loves to enter his life because he may end up hurting them. She also says if Miharu wants to stay by Haruto's side once more, there's one opportunity to do so (when he reveals his true identity) and tells her not to run away if that opportunity comes. Thanks to Satsuki who gave Haruto advice, he could accept himself and Miharu once again. She later tells Sendou Takahisa that she's in love with Haruto as his past and as Rio. Takahisa attempted to kidnap Miharu but Rio foiled his plan and came saving her (also carried her like a princess).

While in the WN, Miharu keeps comparing Rio with the previous Haruto, Miharu realizes that she's fine just being around Haruto. Later on, Aishia plays Haruto's life in Japan as a dream to Miharu without explanation, completely scaring her. When she reunites with Takahisa and he hugs her, the contents of the dream came to her head and Miharu completely flips out, trying to tell Haruto, watching confusedly, that he shouldn't misunderstand. When Takahisa asks her to come with him to the Stellar Kingdom, Miharu refuses him and states that she wants to stay with Haruto. At the party, Haruto confesses his love to Miharu, so clearly without letting any chance of misunderstanding, but before he confessed who he was and Miharu answers, their confession got disturbed by Aki and Takahisa. She then gets kidnapped by Takahisa to the Stellar Kingdom, and only several months later does she know who Haruto is after Liliana gives her the letter from Haruto that Takahisa intercepted.

Sumeragi Satsuki
In the beginning, Satsuki was quite wary of Rio. From time to time, some men approached her aiming at her title, and Satsuki considered Rio's way of approaching her was even more ridiculous, but when she realized that he was testing her to see if she could be trusted, she found him trustworthy. Satsuki hates the new world, it suddenly and forcefully took everything away from her, stranding her in a strange and unknown land all alone; the food and bath don't meet her standards; and above all, her freedom is restricted. Meeting Rio brought her salvation, he prepared her Japanese meals, a familiar bath, a chance to reunite with Miharu. He even showed her the beauty of the world. When she hears his history, she becomes awed with him even more, she finds him to be a kind person, and gradually develops feelings for Rio. To Satsuki, Rio is her hero.

Rui Shigekura
He's Rio's friend. The first time Rio met Rui was in a banquet in the Galarc kingdom. Rio and Rui work together against the enemy who is attacking, After Rio and Rui managed to defeat the enemy. King Francois gave a gift to Rui, then King Francois gave the name of the title of an honorary knight to the young Rio. After Rio mentioned the name "Haruto Amakawa" it made Rui curious because his name sounded Japanese. After Rio spoke to Satsuki and Miharu, Rui came to him to ask him about his name, Rio answered him.

The two of them meet again when Christina runs away, Rio manages to beat Rui and Alfred is still unconscious. Rui is happy to accept his defeat the first time, Rui asks Rio to guard the city and Rei. Rui and Rio promise each other that if they help in the future, the two of them will become friends.

Charlotte Galwark
Galarc kingdom's second princess, when she was in Galarc's royal academy she used to drink tea with Liselotte two or three times per week but after she graduated from the academy and moved to Amande they got a little distanced, the same as her family since the hero summoning she has been trying to befriend Satsuki and to earn her trust, the fact of her being a fellow girl and to be relatively free-spirited compared to other girls her age made her the person Satsuki thinks the easiest to talk to in the castle but even with that Satsuki never considered her someone to lower her guard to. She has a crush, Rio suspecting already of her bad personality doesn't reciprocate her feelings.

Liselotte Cretia
Liselotte Cretia is the youngest child and the only daughter of the Cretia Family, a prominent noble household in the Galwark Kingdom. She is the most sought noble daughter in the whole country and can even be considered an unreachable flower.

She graduated from the royal academy by skipping grades several times, built a business that grew into an international enterprise famous in even neighboring countries, became a governor, and developed land that she got from her parents into one of the most prosperous cities in the kingdom, all while still just 15 years old.

A smart, beautiful girl with duke rank connection, a prosperous city, and successful company, all of those would fall to the hand of any man that got her hand. Attracted by that, Liselotte become so sought after she keep receiving a marriage proposal from noble from all over the country, even up to the same duke rank.

Yet no one managed to successfully take her hand, there's also no news nor rumor about her getting close with any man, she never interacts with men outside of business or work, until she came to the Galwark Hero Introduction party with Haruto as her partner.

Liselotte possesses the memories of Minamoto Rikka, a high school girl from Japan. As Rio, Liselotte had no idea they met before because Rio wore a hood with the sole objective of keeping a low profile due to his status as a fugitive. While Rio suspects Liselotte is a reincarnator from all the modern items the Rikka firm sells, he had no idea that the clerk serving in front of him was Liselotte herself. As Haruto was a traveler their relationship started quite stiff, mostly because Haruto was being overly cautious toward anyone from noble society. He had suspicions about Liselotte from the Rikka guild due to the availability of modern world items, and he thought Liselotte would be a threat if she wanted to keep the secrets of the Rikka guild under wrap. In actuality, it was the opposite, being Liselotte produced modern items out of loneliness, she hoped to find someone who also reincarnated like her using her guild's modern world merchandise as a sign. While Liselotte sees Haruto as an overly capable man, his manner, ability skill in conversation and negotiation, his strength, everything about him is something she's never seen before in her life as a noble. After she watched him fight in a monster raid, she couldn't see the full potential of his strength and is awed by him. At first, she tried to gain his favor by using her beautiful chamberlain with no result, she got more chances to interact with him when they went to the party as partners, something that created an uproar in the noble society. Though when they meet the hero, Satsuki, she has a strange feeling after hearing Haruto pronouncing Satsuki’s name naturally.

After Haruto receive his title, Liselotte was grumbling about how everybody's trying to cut in line even though she was the one that stumbled upon him first. Aria advised her to stop approaching him with half-assed plans and to just go for him sincerely as a single woman because that's the only way she thinks that will somehow have a chance against Haruto. The next day, Haruto visits the Cretia family as a farewell before leaving the kingdom, telling the Cretia his official name, Amakawa Haruto, something that shocked Liselotte big time. Liselotte's next meeting with Haruto was when he escorts Christina to the Restoration, Liselotte took that chance to ask Haruto if he believes in a previous life only to change her mind and pull back her words; she asks once again after returning from the Restoration only for Haruto to give a vague answer and apologizes because he has an urgent business up north and has no time for that kind of discussion. Her next chance was when she heard that Haruto was going to escort Christina to Galwark and requested to accompany them. She spent the entire time pulling a poker face dealing with Charlotte's antics until she got Haruto to spare his time for her alone.

Liselotte secures time alone with Haruto in his mansion where she once again asks if Haruto believes in a previous life in which he once again answers vaguely, she then told him that she knew him in the previous life, something that for once, shocked him. She asks why he keeps answering vaguely, Haruto answers as a precaution that Liselotte is noble, and there's a chance she'll try to silence people that know her secret (an answer that truly depressed her). Haruto then asks why she makes modern items, Liselotte simply answered that she's lonely and wonders if there is someone else with the same circumstances as her. Haruto then told her that she's someone he trusts the most in Galwark now, and now that he's somehow part of Galwark nobility, he intends to maintain a friendly relationship, something that makes her happy.

When Rio arrived at the village she would welcome and guide him towards Yuba's house along with Ruri, at that moment she would fall for Rio at first sight and would become to address him as Rio-sama because of Rio's polite speech and in her opinion how he had the same unreachable aura that the nobles have.

That night Sayo would even ask to be allowed to sleep in Ruri's room for not seeing Shin at that time.

A month and a half later Rio went again to the capital for giving his new year greetings to his grandparents. Rio would come back a month later accompanied by Komomo and since then, little by little her place next to Rio and Ruri was taken by Komomo. Three months later Rio would talk to her about his intentions of leaving the village after the next harvest festival, after knowing that she would begin to cry more and more after going back to her house, when Shin sees her in that state he would go to Yuba's house and beg Rio to stay in the village making dogeza, Sayo tries desperately to stop him and they would say to Rio to leave that at nothing.

The next day Yuba would say to Sayo that the chance of Rio staying is zero, that he's leaving with a goal in mind and that stopping him is impossible, from then on she would begin to train her spirit arts for being allowed to Rio without pulling his leg, she would spend so much time training that for the next six months she wouldn't talk to Rio anymore, the day of the harvest festival she confesses to Rio and rejected by him, after that while Shin tries to cheer her up Gouki would appear where they're and would offer to them to secretly follow after Rio with him, or so it was hinted because Gouki's group hasn't appeared yet again in the novel and it's still unconfirmed if they followed after Rio or not.
