Rio Karasuki/Relationships

Celia Claire
Celia was Rio's teacher and his only companion when he was studying in Bertram Royal Academy. During his stay in academy, she would help him whenever she could and Rio would do the same for her. For instance, on the first day of school, she taught him how to read numbers after knowing that he could not read nor write numbers. On the other hand, Rio would help to clean up her laboratory, prepare tea and snack for their tea break and organize her research material (although, Rio helped because he couldn't tolerate Celia's messy room). She gradually fallen in love with Rio and only found out after Rio decided to leave the country when he was framed for attempted murder towards the royalty. When Rio returned to Bertram kingdom to visit her, he found out that Celia was forced to hold a political wedding with Charles Arbour as his seventh wife. Rio saved her by kidnapping her in front of all the guests and Charles Arbour.

Due to his past history in the Beltram kingdom (false charge against him) Rio is extremely wary of Flora. At the same time he has no grudge to princess Flora as she 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 Beltram kingdom to recognize Rio despite his disguise. During the academy era, 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 Beltram
Rio first meet with princess Christina in the slum as she was searching for her abducted sister Flora. The princess did not know how to interact with common people and slaps him because she believe he kidnap her sister.

Rio meet with her at the banquet in the Garlac kingdom presenting the hero Satsuki, despite being watched by the Arbour faction, she secretly thanked him for saving her sister in Amande. After, Rio meet with her again as he accompanies Celia in Cleia. Christina has escaped the Arbour faction and asked him help her for going to Rodania. Seeing the trust between Rio and Celia, she suspects Haruto Amakawa to be Rio, suspicion confirmed by Reiss later.

Zen
He is Rio's father, he passed away shortly after Rio's birth. He was an adventurer and a former royal guard of Karasuki Kingdom.Five or six years before Rio's birth, the Karasuki kingdom had already been at war with the Rokuren kingdom for a long time, something that was making the life in Zen's village and the other villages through the kingdom really hard, Zen then decided to leave his village in prder to reduce the number of mouths to feed in his house.

After leaving his village Zen joined the kingdom's army, once there thanks to the talent for the spirit arts and military arts that Gouki said that he had, Zen distinguished himself quickly, it didn't take long for him to be know as a hero of war in the whole kingdom and the king decided to give to Zen he samurai title.

The tradition says the those named as samurai must have a duel after the ceremony with one of their senior, the chosen in Zen's case was Gouki, that at that time was already famous as the strongest inside the Karasuki 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, then he would begin to work as Ayame's bodyguards with Gouki and Kayoko.

Ayame would feel attracted to Zen quickly because for her he was the embodiment of everything she always wished for, the world outside the castle, she would teach to Zen with Gouki and Kayoko the manners and etiquette necessary for a royal guard, later by Ayame's insistence and without paying mind to Zen's reluctance they would visit in secret Zen's village several times.

Months later the Rokuren kingdom would propose a ceasefire to the Karasuki kingdom and would send its prince as an embassador, the night that everyone was celebrating the stopping of the war, that prince would order Ayame's kidnapping, Zen would detain the kidnapper but this would suicide just after, the prince from the Rokuren kingdom would make his vassal's death as a personal attack against him and would add Zen's execution and a marriage with Ayame as conditions for the ceasefire.

The king would pretend to agree to it but at the same time would order Zen to run away from the country with Ayame, while the king earned then time would make preparations for winning the war and would succed, but at the cost of Zen and Ayame losing their place in the Yagumo region with a bounty in their heads for desertion and kidnapping of a royalty.

After arriving to the Stralh region Zen and Ayame would begin to work as adventurers while living traveling from place to place, after Ayame got pregnant of Rio they settled in Bertram's capital where they bough a cheap house in a district relatively good outside the castle walls, while they were adapting to the city Lucius would approach them pretending to be a good friend and when Rio was still a newborn he would kill Zen while making it look as he messing in the job, Zen earned enough money for Ayame to not need to work for paying for hers and Rio's living after his death, but five years later Lucius would finally reveal his true colors and after raping and killing Ayame on front of Rio he would stole everything from them and abandon Rio in the slums.

Ayame Karasuki
She is Rio's mother. She was a princess from the Karasuki kingdom in the Yagumo region, after Zen becomes her bodyguard she would quickly get attracted to him as he would often tell her stories of the outside world. She would, along with Gouki and Kayoko silence the people against Zen being her bodyguard and would teach him all the necessary manners and etiquette for a royal guard. She would often ask Zen to be taken outside of the castle to places like his village, no matter how much he tells her that there wasn't anything interesting there. Her father realized their feelings for each other long ago and wanting to let them getting married wasn't able to because the nobles from other factions wouldn't allow her to get married with an upstart like Zen despite being famous as a hero of war throughout the kingdom and she herself having a low position in the succession list.

The night that the Karasuki kingdom was celebrating the end of the war against the Rokuren Kingdom, the prince of 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 Bertram's capital when she got pregnant with Rio.

Once in Bertram's capital they bought a cheap house in a district relatively good outside of the castle walls and began to live there. During the time 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 during 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 living during his childhood, Lucius still making the acting like a good friend towards her extended a helping hand during the next five years, then the day when Lucius finally showed his real colors came and he raped and killed her in front of the five year old Rio.

Karasuki Homura
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 to get married he wasn't able to because the nobles from other faction's wouldn't have seen with good eyes a marriage between a princess like Ayame, despite her post in the succession list being low, and an upstart like Zen, despite him being famous as hero of 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, them with the time that he gained with his charade he 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 weighted 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 for not doing some insanity for the sake of avenging his parents he chose to not stopping him and instead lending a hand.

He ordered Gouki to have a mock battle with Rio, expecting Rio to be defeated by him to afterwards convincing him of living in Gouki's home as his disciple and stay 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 anbus 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 it was never specified the cause, the most likely in a war somewhere, since then she was raised alone by Yuba, she's equally close to everyone in the village with the exception of 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 decide to talk 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, she 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 to consider her as his only important conversation partner, when all the boys got jealous of all the time that Rio and her spent together she never paid it any mind and defended Rio from them.

Latifa
Latifa was ordered to killed 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.

Several years later, after her first day at the 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 a grassland near the border of the Galarc kingdom with the Centostella kingdom, they walked together until a highway, there 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 them that they were in another world now, 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 to kidnap Miharu, after the kidnapping incident she was sent to the Centostella kingdom with Takahisa where Masato is currently watching over her rehabilitation.

Sendou Masato

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 high way where a slave trader spotted them and kidnapped them to be rescued a little later by Rio, his older stepbrother Haruto's reincarnation.

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 he himself, he was so fixated in how big was his presence in his friends' and siblings' hearts that he didn't pay any mind that 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 would 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.

When they reached the age to enter High School, Haruto returns to the city where Miharu was and managed to enter the same school by chance. After knowing that 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 relationship. After few days of hesitation, Haruto decided to talk to Miharu face-to-face to remove the regret for not facing her. However, the regret cannot be eliminated 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 of how to interact with her again as his moral values were different from those when he was Amakawa Haruto. He also detested the idea of involving Miharu and those he holds dear into his revenge toward Lucius. This stemmed form the fact that he felt guilty of killing people despite being necessary. Hence, he felt that he is not qualified to be close to her nor is he qualified to attain happiness.

Later, Aisia bestow 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 aggressively when compared to her usual shy/timid personality).

Aisia also warn Miharu that Rio is kind but cowardly person as he doesn't want people he love to enter his life because he may end up hurting them. She also says if Miharu want to stay by Haruto's side once more there's one opportunity to do so, when he revealed his true identity and tells her not to run away if that opportunity comes.

She later tells Sendou Takahisa that she's in love with Haruto as his past and as Rio, Takahisa attempt to kidnap Miharu but Rio came and saving her (also carried her like a princess).

While in WN, Miharu keeps comparing Rio with the previous Haruto, Miharu realizes that she's totally fine just being around Haruto though he supposedly are stranger boy, later on, Aishia put Haruto's life in japan as a dream to Miharu without explanation, completely scaring her, when she reunited with Takahisa and he hugged her, the dream comeback and Miharu completely flipped out, trying to tell Haruto that watching confusedly that he got it wrong, when Takahisa asks her to come with him to Stellar Kingdom, Miharu refuses him and stated that she want to stay with Haruto, in the party, Haruto confessed 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 get forcefully taken away by Takahisa to Stellar kingdom, and only several month later she know who Haruto is after Lilyana gives her Haruto letter that Takahisa took.
