Plot
Ever since he was a young child Sora Aoi had always exchanged words of "I love you" with his 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.

Aoi family

 * Sora Aoi (葵 ソラ)
 * Sora is the protagonist of this story. His first name is written as 蒼空 (Sōkū) in kanji. He studies in the same high school as his sisters, Aki and Nami. Unlike his sisters, he is good at cooking and housework. 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. His aunt also notes him to be a timid person, and slightly a pushover, which further allows him to be forced to cross-dress and sexually approached. Sora has a low alcohol tolerance, as he falls unconscious by drinking even a little sake. He is deeply in love with Aki, and doesn't 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 the latter two he was forced. Sora claims that, despite being forcefully raped by Nami, he does not hate her. He is, however, terrified of her after she threatened to emasculate him, and then kill him for good if anything about the rape should ever be brought to the light.

 * Aki Aoi (葵 アキ)
 * Aki is Sora's elder sister. Her first name is written as 亜希 (Aki) in kanji. Attractive, athletic, and intelligent, she’s considered a model student at school and is highly popular. 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, by molesting him in an attempt of seduction, but is unsuccessful, as Sora ran out of there in embarrassment. However, her second attempt, in his room, is successful, after she gave him a heart-felt confession of her love towards him. After that, they have engaged in sexual intercourse many times, including in public places, such as the school gym's storage, an onsen, and on top of a ferris wheel. During these times, she doesn't want to be called nēsan (elder sister), but Sora feels weird saying her name. She seems to be unaware that he has had sex with other women, other than herself. Due to their constant sex, Sora's school test scores were lowering, and Aki refuses to have sex with him anymore until his grades improve, and she cries at the idea of it being her fault of dragging Sora's grades down with her flirting. In Chapter 19, after noticing how close Sora and Nami seem to be, Aki takes him to an out of town hotel. However, on the train there, Sora seems to reject her advances. Next at the park, when she tries again, they almost got caught.

 * Nami Aoi (葵 ナミ)
 * Nami is Sora's younger twin sister who looks completely identical to him (though in the anime her hair is slightly darker than Sora's). Due to their same appearances, Nami ties her hair in pigtails, but her hair is slightly longer than Sora's when let down, the only noticeable physical difference aside their gender. When they were children, she'd often pretend to be Sora. Even though they look alike, their personality are polar opposites. Unlike the quiet and well-behaved Sora, Nami is a blunt and can be incredibly stubborn and harsh, but also quite eerie and menacing towards her brother. For instance, she had a habit of smashing his toys when they were children out of jealousy (suggesting she suffers from GIDC), and often forces Sora to cosplay for her own amusement. Like Sora, Nami has a low tolerance to alcohol. 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, however backfired and drove her over the edge, 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. In a fit of psychotic wrath she assaulted Sora and, after almost cutting off his penis and slitting his throat with a pair of scissors, she proceeded to rape him, fantasizing during the whole act that she was making love to Kana. She obtained his silence through a death threat, and since then Nami has repeatedly had sex with Sora. While vocally expressing her disgust at the act, she is becoming more and more obsessed with it, almost craving it, though 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 they have been much closer to each other.

 * Aoi family mother (false) (葵家の母親)
 * The as-of-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. Everyday, 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 (real) (葵家の母親)
 * 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.

Classmates

 * Kana Sumiya (澄弥 可奈)
 * Kana is Sora's classmate and Nami’s best friend. Kana and Nami are the only members of the cosplay club. She makes female outfits for Sora and Nami forces these outfits unto her brother. She has feelings for Sora but is too shy to confess them. She is unaware of Nami's feelings towards her. Even when Nami stated she loved her, Kana believed it meant because they were friends. After a date, at which Kana gave Sora a kiss and a boob-job, Nami, who was witnessing from a cupboard, snapped, leading to her raping Sora. In chapter 16, she loses her virginity to Sora, which Nami secretly records. It is vaguely expressed that Kana loved Nami at the end of Chapter 16. Kana remembers the first time she had met with Sora, and believed it was fate, because she had the chance to love a boy who looked exactly like Nami.

 * Runa Satsuki (咲月 ルナ)
 * Runa is Sora's senior at school. Ever since being forced to walk home from school only wearing her school swimsuit, she's been an exhibitionist. Sora first meets her as she was changing bare in the elevator at their apartment complex. She mistakenly thinks Sora finds cross-dressing exciting. She later forces Sora on a "fetish" date with her—she is wearing only a raincoat, and he is in drag—and forces him to masturbate to her masturbating. In chapter 6, she tricks Sora into going to a swap sex orgy with her, as her pretend-boyfriend. She loses her virginity as Sora watches. They held hands through random partners. In chapter 11, she takes him to the pool having him wear a girl's bathing suit while she painted a swimsuit on her body, where she pleasures Sora for helping with her exhibitionism again. It is unknown whether she has any feelings for Sora, however she has stated that it is only "good" if he is the one to see her naked. Because of this she has not returned to the "party", even though asked many times. She returns in Chapter 20 as a nude art model.


 * Natsumi Nosaka (野坂 なつみ)
 * Natsumi is Sora's classmate. She attended the party that Hitomi had, and was one of the many girls to have set eyes on having sex with Sora. She felt a little annoyed when Sora had difficulty at remembering her at first sight at the party.


 * Alice Himekawa (姫川 ありす)
 * Alice is Aki's classmate. She is a beautiful girl with blond hair, girlfriend of Miharu Mihara, the school's student council president and self-proclaimed rival of Aki. As Alice is second place in the test results (under Aki), she tends to act distastefully towards Aki. Aki, however, is oblivious to this rivalry and considers themselves as friends, much to Alice's irritation. Due to this rivalry, when Miharu asked Sora to have sex with Alice to satisfy her in his (Miharu) place, Alice was skeptical due to Sora being Aki's brother. Regardless, Alice loved Miharu dearly, and agreed to have sex with Sora, and even giving up her virginity to him. In Chapter 18, all three play a fantasy game, in which Alice rapes Sora for real while Miharu watches.


 * Yuna Asana (朝菜 ユウナ)
 * Yuna is the president of the school's art club. She agreed to let Runa take over as a substitute for the nude model in class, but noticed that the boys were looking at her more than drawing, and got angry at it. However, Runa correctly guessed that Yuna was aroused by the atmosphere.

Others

 * Hitomi Tomozaki (友崎 ひとみ)
 * Hitomi is Runa's friend. She held the orgy party that Runa tricked Sora into going, and had her sight set on Sora at the party's start. She was the first one to have sex with Sora at the party, and her boyfriend was the one who took Runa's virginity. After this party, Hitomi invited Runa to return many times, but because Runa only felt good with Sora, she did not return.


 * Miharu Mihara (美原 みはる)
 * Miharu is Sora's childhood friend who used to live in the same apartment complex with the Aoi family. He is younger than Sora, and Sora addresses him as "Mi-chan", and would view him as a younger brother, were it not for Miharu's tendency to cross-dress as a girl. Miharu has an effeminate appearance, similar to Sora, but unlike Sora, he likes to cross-dress. He came to Sora's school in order to ask Sora to have sex with his girlfriend, Alice, because Miharu himself has erectile dysfunction, in order to make Alice happy. Miharu is shameless, as he not only cross-dresses and asks his friend to take away his girlfriend's virginity, but also narrates about Alice and Sora having sex with vulgar phrases. He got over his conditions only when witnessing Alice and Sora having sex. However, once Sora leaves and it was his turn, Miharu became ED again. Therefore, he asks Sora to take care of Alice.
