History
When Aki was a baby she was always with Haruto and Miharu, she was capable of understanding how special Miharu and Haruto were for the other, because of that it made her feel special to be the only one that was allowed to enter in the world that they used to create for themselves, she was always being doted on by them, she always slept next to Haruto and when Miharu stayed the night she slept between the two.

When she was four, Haruto's father discovered that her mother Yuki cheated on him and that Aki wasn't his daughter and they got divorced; Haruto's father went back to Haruto's Grandfather's house and took Haruto with him and didn't allow any information about Aki and her mother to reach Haruto nor did he let them contact each other again.

Aki and her mother too moved to another place from the house they used to live in, even though her mother kept her relationship with Miharu's family, Aki missed her brother, she always cried and called for him but he didn't come back, even though their mother always cried alone at night while apologizing to him he never came back, even though he promised to always be there to take care of her he didn't come back, even though her mother that was always kind with her was having a lot of troubles raising her alone Haruto and her father didn't come back, even though her mother fainted at work due to the over effort they didn't come back. little by little Aki's sadness turned into anger and finally hatred, one day Miharu mentioned Haruto in front of her and she got really mad at her, talking about Haruto became a taboo till the point that he was never mentioned again and his step brothers were never told about his existence.

Years later her mother got married again with Takahisa and Masato's father and having her new siblings helped her to fill the whole left by Haruto to an extent, later she would meet Satsuki through Miharu and Takahisa and she would begin to look up at her as a little of a superwoman because of her strong personality and independence.

Dragged to Another World
In her way back home after her first day at middle shool 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 took the three to the rock house and explained them that they were in another world now, he explained a little about the time and space sorcery and made dinner for the four with Miharu, the next morning Aisia awoke and with her help he taught the stralh's language to Miharu, Aki and Masato, then Rio teleported to the spirit folk's village for asking the elders permission for hiding the three there, two weeks later Aki had an argument with Miharu because she said to her that Rio's aura resemble Haruto's, Aki got out the house and put her back against the wall while curled like a ball on the ground, she's thinking that it was to shout at Miharu when she herself got reminded of Haruto because of Rio, Miharu got out for making up with Aki, then she realized that there were two grey revenants trying to pass through the house's barrier, Aisia appeared and shot shockwaves at the revenants, while Miharu and Aki were going to inside the house a dark grey revenant passed through the barrier and was going to attack them but Rio that has just come back stopped it, Rio and Aisia killed the revenants and the next morning everyone teleported to the spirit folk's village.

Life in Spirit Village
At their arrival Rio introduced everyone to Sara, Ouphia, Alma and Latifa, there he explained to everyone that his real name was Rio and that he was using Haruto as an alias because he was framed four years ago, Miharu and Masato agreed to keep calling Rio as Haruto for not getting it wrong when going back to the Stralh region, Aki agreed to with a complicated face, but since then in her head she called Rio as Rio and not Haruto, Rio took everyone to the government's built where the elder welcomed them and said that there will a welcome party for everyone that night, in their way to the tree house were Rio uses to live in while in the village, in their way they were introduced to Vera and Arslan.

The next morning everyone saw Rio having a mock battle against Sara, Ouphia and Alma at the same time and then another with Uzuma, on the afternoon Aki saw with everyone how Rio tested Masato, she tried to stop it when she saw Masato nearing his limit worried about him, but Masato refused and continued, Aki then stayed in the village for two months and a half learning spirit arts from Ouphia, she and Masato were able of learning to control their magic power, to see it and to feel the mana but haven't manage to controlling the mana and activating it successfully.

Rio came back from the Stralh region after his visit to Celia with news about Satsuki, but not about Takahisa something that disappointed Aki, Rio explained to everyone in front of the elders that he would attend the evening party and asked Miharu, Aki and Masato what they wanted do now, while thinking what to do Aki went to look for Miharu wanting advice, then she overheard Latifa telling about her previous life to Miharu in exchange of knowing her feelings for Haruto and Rio, after hearing the conversation Aki run away from them.

After having lunch with everyone Miharu called Aki and Masato to her room and told them her plan of attending the evening party with Rio just her and them to wait at the rock house in the meanwhile, Aki and Masato accepted, there was a farewell party for them two days later where they said their farewells to their new friends Vera and Arslan, the next morning they left village headed towards Galarc's capital.

Bad Reunion
Two weeks later everyone arrived to the rock house near Galarc's capital and met Celia, all the girls took a bath together while asking Celia about her impression of Rio and his past, Aki then looked with complicates eyes at the Miharu that didn't knew if declaring herself as someone who wanted to know about Rio's past or not.

Weeks later, the night before the evening party Rio and Miharu brought Satsuki to the rock house, after talking a little about how everyone did after the summoning, Satsuki warmed her, Miharu and Masato to be prepared for even living separated if Takahisa is the hero from the Centostella kingdom because then they will be asked who they want to stay with, and everyone might to choose a different path. Three days later, Aki was informed of Takahisa's presence at the party, when asked by Miharu and Rio if she wanted to meet him she quickly said yes, then Rio said to her too that he was Haruto's reincarnation, Aki reacted denying to be Haruto's sister and began to ask him screamed and angered why did he have to tell her that and why he couldn't let her think of him as just her savior, then Rio explained to her how Haruto met their mother Yuki again a little before being twenty, how because of that he knows that Miharu was still missing, with Haruto dead, it may be impossible for them to return to Japan due to the differences in the timeline. He told her about his previous life for the sake of explaining that, after listening to that Aki shut herself in her room.

Rio took Aki and Masato to the castle the next morning for them to meet with Takahisa, after the reunion the Sendo siblings were let alone with Miharu and Satsuki, after talking a little about what happened to everyone after the summoning, explaining to Takahisa about Rio's previous life, his relationship with Haruto and that they may be unable of returning to Japan the conversation moved to who will live with who, Aki was the only one who wanted to follow Takahisa to the Centostella kingdom while Miharu and Masato wanted to stay with Rio, after hearing from Miharu that Rio was reluctant to let them stay with him Aki said to call Rio back and to make him participate in the conversation too.

When Rio comes back to the room Aki and Takahisa will ask him about his reluctance to let Miharu and Masato to stay with him after the evening party, that travelling with him may be dangerous and he prefers Miharu and Masato to live in a safer place if possible, now Aki asked him if it's true that he doesn't let Miharu to call him Haru-kun anymore and that he doesn't call her Mii-chan either, Rio will repeat to Aki what he already said to Miharu several times that he isn't Haruto anymore, if Miharu goes with him expecting everything to be as when he was still Haruto she will regret it, then he asked Aki if she's thinking about him as Haruto too. Aki won't deny it because she thought of the words that Rio said just now as a convenient way of running away from Miharu and her, and now in her heart anger towards Haruto will began to fight with the loneliness she has felt since she knew Rio was Haruto's reincarnation because Rio calls her Aki-chan instead of just Aki like in his previous life, the same way that he has refused until now to address Miharu as Mii-chan, in the middle of the talk Satsuki got mad at Rio and made him to have a duel with her, after losing against Rio she asked him to not hold back his own feelings anymore for the sake of Aki and Takahisa that she realized already a part of his reason for wanting to send Miharu to the Centostella kingdom was for Aki's sake.

Evening of that day, Rio goes to the Sendo siblings' room and tells them that he isn't going to force Miharu or Masato anymore to go to Centostella if they don't want it, Masato is happy but Takahisa is angered, he calls Rio hypocrite for changing his words, he asks why is he stealing them from him if he doesn't really want them to be by his side.

Aki asks the reason for the change while upset, if he doesn't believe anymore that he and Haruto are different people, he says he still believes it. Aki says then why? Rio says he understood that with his actions he wasn't really respecting their freedom to choose, Aki says to him how she believes that his words of him Haruto being different people is just a convenient excuse for running away from Miharu and her, Rio says again he is different from Haruto, he has done already plenty of things that Haruto would never do, Aki asks what things, Rio says like killing people, Masato is slightly surprised, Aki freezes on the spot, partly for the revelation and partly because she's at least beginning to realize Rio and Haruto are different people, Rio continues and talks about his revenge.

Takahisa is angered, he says Rio deceived Miharu that it is impossible for her to want to go with Rio while knowing that, Rio says Miharu and Satsuki already know everything. Aki gave up on convincing Miharu while thinking "Are you idiot Miharu onee-chan?".

Takahisa is surprised of knowing Miharu and even Satsuki was always the reliable and wise senpai accepted such a thing and says that he won't allow Miharu and Masato to go with the kind of dangerous person that killed someone and with a criminal saying that is going to kill other people, Rio says very clearly, calmly and directly to his face "I don't need your permission" (this part was really pleasant to read), Takahisa asks for a duel and if he wins Rio will refuse to have Miharu and Masato with him, Masato joints the bet completely convinced of Rio's victory and says he will have to give up too if he loses, Aki is terribly flustered hearing this because she thinks that like that the brother relationship will break irredeemiably, while seeing Rio get out she wanted to call out to him for talking more to him but in the end she didn't dare to.

After the duel Takahisa still refuses to acknowledge his defeat, he isn't in his right sense anymore, he begins to say he has to kidnap Miharu and that once she separates her from Rio she will go back to her senses again that if he confesses to her she will surely follow him and threats Liliana with not being a hero anymore if she doesn't help him. Liliana asks Aki for help to calm Takahisa and she says, "Onii-chan I will go with you, isn't it fine if it's just me", Takahisa stays silent, saying no with actions rather than words.

For Aki, it was already a trauma big enough to have to part with Haruto, she barely held on for his mother's efforts and because Miharu was there, and his new older brother even with unreliable parts still on him her wounds finally get cured, she was sad because Miharu wasn't with her, but because her brother was still there she was somehow still fine, so when Takahisa her only important person left said he would abandon her too something broke inside her, and in the end, she helped Takahisa because it was necessary in order to not be left alone by her important people again.

The evening after losing the duel Takahisa says to everyone that it seems to be better for him to go back already to Centostella to cool his head, he gathers Rio, Miharu, Satsuki, Aki, Masato and Charlotte in one of the castle gardens, Takahisa gives false apologies to Rio for the things he said about him and lowers his head, Rio accepts the apologies while worried that the place where they were called has almost no guards, then after everyone says farewell Charlotte takes Satsuki and Rio with her saying there is something they need to talk about, Rio leaves Aishia behind because he's worried about the lack of guards around, then Aki takes Masato with her to somewhere else with the excuse of having forgotten something in her room while making it look as Takahisa wanting a little of time to talk just with Miharu, Masato that just thinks that his brother has something to say to Miharu because he likes her agrees to leave the place with Aki, and so Takahisa and Miharu are finally left alone with Aishia watching them in her spiritual form while linking her five senses to Rio to make him hear the conversation of the two.

Sometime later, soldiers come looking for Aki and Masato, Aki was taken to the same room that Takahisa while Masato was taken to the room where Miharu and Rio will explain to him about the failed kidnapping, Satsuki and Liliana enter the room and Satsuki begins to talk to the two, Takahisa just has an annoyed face while Aki is worried and almost crying, she says to Aki that looking at her face it seems there is conscience that she did something bad, what about you Takahisa-kun?

Takahisa looks other way without answering her, he was going to begin again his partner about Rio being a criminal but Satsuki stops him at the beginning, out of the question, what you really can't take is that Miharu likes another man, did you thought that lowering the other's evaluation Miharu would choose you instead of him? Takahisa loses his words when completely seen through.

Satsuki tells the two that they're forbidden for seeing or talking to Rio and Miharu for some time and that Aki will go to Centostella she wants it or not now. Takahisa doesn't say anything. Aki begins to cry when hearing she won't be able of seeing Miharu and because she realizes that it's because of something she did with her own hands. Satsuki then tells the two half crying that it was her who asked Rio to properly talk to the two for the whole group to be able of advancing forward but you went and did something like this, both lose their words again, and Liliana tells Takahisa, I told you, do you know what is coming now? then when they're leaving the room they find Masato in the door, he says the two he wants to talk with his siblings a little and that he has Rio's permission.

Masato enters the room and talks to them but Takahisa still doesn't reflect in the slightest and Aki just cries more and more, Masato tells her while consoling her that if she's going to cry then don't do it to begin with. Two days later, Aki was taken to the Centostella kingdom.
