Plot[ edit ] Ever since he was a young child, Sora Aoi had always exchanged words of "I love you" with his attractive older sister Aki. Now, as he comes of age, he finds it much harder to exchange such comforts as they did in those simpler times. When Aki demonstrates her feelings toward him to go beyond a sister's love, Sora finds himself questioning his feelings for his sister. Realizing their affection for one another, they consummate their love in secret.
In a society that would never understand, they must now keep their love a secret from their family and everyone they know. However, Sora soon finds himself exploring many forms of love with different kinds of women he met that is not accepted by society thus questioning his feelings for his sister. He studies in the same high school as his sisters, Aki and Nami. Unlike his sisters, he is good at cooking and housework. Sora has a low alcohol tolerance, as he falls unconscious by drinking even a little sake.
Due to his upbringing without a father or any male figure in the household, as well as questionably awkward relationships with his sisters, Sora was raised with virtually no masculinity of any kind. Almost all of his postures, behavior, and mannerisms are those typically expected from a shy girl. His effeminate appearance makes him a perfect candidate for cross-dressing , which he finds himself engaging in involuntarily because of Nami's fetish and Runa's belief that he enjoys it.
He is very shy and very much a pushover, and completely lacks the will to stand up for himself against girls, which further allows him to be forced to cross-dress and sexually approached. Indeed very much every girl around him is immediately privileged with the opportunity to rape him, which some of them did or attempted to undeterred by his discomfort and protests.
He is deeply in love with Aki, and does not resist her the second time she tries to have sex with him, but he does question himself at times whether their incest taboo should be continued, since they have no future in a relationship.
He has also had sexual relationships with other people, such as Kana, Runa and Nami, though with the latter two he was forced. After being raped by Nami, who then threatened Sora with emasculation and death if anything about the rape should ever be brought to light, he became terrified of her, but claimed that he does not hate her.
They eventually rekindle their relationship when Nami asked for consensual sex, and had since then became more close.
In the final chapters, Sora fully accepts his relationship with Aki, even defending it against their father. When Aki is taken away by their father, Sora is lonely and wants to see her again. After Aki chooses to go away so that Sora would not be hurt by their love, Sora is heartbroken and realizes that he truly loves Aki and wants to be with her. In the final chapter, they meet at their mother's grave. However, at home, she has no culinary talents and fails to keep her own room clean.
She is deeply in love with Sora. Unlike the rest of her family, all of whom have blond hair, Aki is a brunette. She first attempts to have sex with Sora in the shower, but is unsuccessful, as Sora runs out of the bath in embarrassment. However, her second attempt, in his room, is successful, after which she gives him a heart-felt confession of her love towards him.
After that, they engage in sexual intercourse many times, including in public places, such as the school gym's storage locker, an onsen , and on top of a ferris wheel. She seems to be unaware that he has had sex with other women, other than herself. Sora's grades drop as a result of the distraction of his relationship with his sister. In response to this Aki refuses to have sex with him until his grades improve, and she cries at the thought of her flirting being the reason that Sora is doing poorly at school.
After noticing how close Sora and Nami seem to be, Aki takes him out-of-town to spend some time together alone. However, on the train there, Sora seems to reject her advances. When she tries to seduce him again at the park, they almost get caught.
Ultimately, they rekindle their romance in a love hotel. However, after their father's death, she decides that they should end their relationship so that Sora does not get hurt any further and says goodbye to him. They later meet up at their mother's grave. Kana Ueda OVA 1 ,  Hiromi Igarashi Yume no Naka Nami is Sora's younger twin sister whose features are almost completely identical to his though in the anime her eye color is red, while Sora's eyes are brown; also, her hair is slightly darker than Sora's.
Due to their similar appearance, Nami ties her hair in pigtails. Her hair is slightly longer than Sora's when let down and this is the only noticeable physical difference between them aside from their gender. Like Sora, Nami has a low tolerance to alcohol. When they were children, she'd often pretend to be Sora, but as they grew up, it became apparent that their personalities are polar opposites.
Unlike the quiet and well-behaved Sora, Nami is blunt and can be incredibly stubborn and harsh, and also quite eerie and threatening towards her brother. For instance, she had a habit of smashing his toys when they were children out of jealousy, and often forces Sora to cosplay for her own amusement.
She has a very strong disregard for Sora's feelings, demonstrated by how she deceived him into signing up for the cosplay club for further cross-dressing, despite his clear discomfort, and upon receiving his resignation letter, she immediately tore it up in front of him without consideration.
She's secretly in love with her classmate Kana, though the latter is completely oblivious of the fact. In spite of this, she's actively trying to get Kana and Sora together. These efforts, culminating with her bearing witness to Sora and Kana having sex together, backfire on her and drove her into a dangerously precarious state of mind.
Guided by the belief that her being a female and thus lacking a penis is what keeps her and Kana separated she assaults Sora in a fit of psychotic rage and, after almost cutting off his penis and slitting his throat with a pair of scissors, she proceeds to rape him, fantasizing during the whole act that she is making love to Kana. She obtains his silence through a death threat, and since then Nami has repeatedly had sex with Sora, rekindling their relationship and becoming more intimate.
While vocally expressing her disgust at the act, she is becoming more and more obsessed with it, especially right after he has sex with Kana, craving her scent. It is unknown if she herself is attracted to Sora, or having sex with him is a way to vent her frustration. She is, however, apparently regretful of what she has done to her brother, though this, coupled with their unhealthy relationship, is gnawing more and more at her already unbalanced psyche.
Despite this, Aki has noted since then that the twins have become much closer to each other. Nami's relationship with Sora is later discovered by Kana, and the three end up having sex together, during which Nami's feelings towards Kana are finally revealed.
Aoi family mother false Voiced by: Hana Aoyama Yume no Naka The as-yet-unnamed mother of the Aoi family, who is actually Aki, Sora, and Nami's mother's identical younger twin sister to be precise, their maternal aunt , but ever since her sister — the kids' real mother — was killed in a traffic accident ten years ago, she has taken over the role as mother.
She took over the role of their mother, and did not tell the twins that their real mother died. She is usually busy working to support the family, and is not there for them, leading them to learn to live for themselves.
She is also somewhat irresponsible, giving Nami some sake, when she is clearly underage, and appears somehow aloof and indifferent, something that puzzled Sora more than once. There is a running gag where she is unable to tell Nami and Sora apart, even when they are naked. Every day, she thinks about whether she should live the role as a false mother, and thought of telling Sora and Nami the truth. Sora himself is starting to question her identity, as she often forgets or is even oblivious of things easily identified by their late mother.
Nevertheless, after being questioned about it by Sora, she even went so far as to procure herself a scar on an arm so as to mimic the one her late sister had, much to Aki's regret. However, they noted that one day they will tell the truth to the twins. In the manga, she was portrayed to have blonde hair, but in the second OVA, she is a light brunette. Aoi family mother true The real unnamed mother of the three Aoi children, she died ten years ago, when she was hit by a car while returning home from shopping.
Her role as mother was taken over by her younger twin sister, and only Aki knows about it. When she first gave birth to Aki, she felt the body was surprisingly light, and offered her sister a chance to hold the baby. She sustained a scar during one Christmas in a cooking accident, in which her left arm was burned while saving Sora from falling.
Eventually, Sora came to know her death, when he visited her grave at the end. Aoi family father The unnamed father of the three Aoi children, who makes his appearance in Chapter He is a big man with dark hair like Aki and is very scary-looking. He walked out on the family when the Aoi children were very young, hence why Sora and Nami do not want anything to do with him. He returns to take Aki to live with him. He caught Aki and Sora when they were making love and punished Sora for it.
It is revealed that the mothers of the Aoi children true and false are, in fact, his identical twin sisters, having had children with one of them, but left his family because society did not accept this. He eventually dies in a hospital from an unknown illness.
