Plot

Nao Takanashi loves her brother Shūsuke despite the incest taboo. Nao thinks that Shūsuke is her blood relative, but in fact she is an adopted daughter, whose parents already died. After Nao learns the fact, she wants to normally fall in love with Shūsuke because siblings by adoption can marry under the family law in Japan. However, she finds herself competing with Shūsuke's childhood friend, Iroha Tsuchiura, and his class president and yaoi lover, Mayuka Kondō.

Characters

Main

Nao Takanashi (高梨 奈緒, Takanashi Nao^?)

Voiced by: Eri Kitamura

Nao, the protagonist of the story, is the adopted daughter of the Takanashi family and secretly loves her brother Shūsuke, going as far as to know everything about him to an obsessive degree. Ten years ago, she was in a car accident which killed her true parents and caused her to lose her memory, and she had only recently learned the truth. She goes to various lengths to make sure Shūsuke becomes attracted to her, such as throwing out his non-incest porn, and becomes particularly annoyed with other girls aiming for his affections. Her real name is never mentioned and her current name is the same as her deceased biological mother.

Shūsuke Takanashi (高梨 修輔, Takanashi Shūsuke^?)

Voiced by: Toshiyuki Toyonaga

Shūsuke is the son of the Takanashi family. He is rather perverted, often keeping large abundances of porn magazines and always looking for panty shot opportunities. Recently he continues to use term which "not betraying Nao" implying he loves her, or at least wishes to have her see him as a good older brother. He does admit to feeling some interest in Nao, not brother–sister interest, but girlfriend–boyfriend interest. He is not aware of Nao's knowledge of either the truth about their relationship or the fact she knows about all his dirty habits. He is quite the heavy sleeper, making Nao wake him up almost daily for school, though Nao does likes this way for she can do the things she wouldn't normally do to him when he is awake, in short this is when she shows her true self.

Iroha Tsuchiura (土浦 彩葉, Tsuchiura Iroha^?)

Voiced by: Marina Inoue

Iroha is Shūsuke's childhood friend before Nao's adoption. Having played Doctor with him a lot as a child (which was Shūsuke's excuse to see her naked), she claims that she is Shūsuke's lover and constantly makes advances on him. She is also something of a stalker, watching him in his house through a telescope and using night vision goggles to stalk him. She is even called a "Genuine Stalker" due to her very detailed reports of Shūsuke's late night actions and activities. Tough she did say that Nao is the most wicked stalker but when only when she said it to herself. She is in constant competition with Nao over Shūsuke's affections, though they occasionally work together when someone else catches his eye. Oddly, despite the fact she has openly stated she is willing to have sex with and even initiating the first move, Shūsuke, he seems to not want this. Though it is hinted this is due to guilt, believing his actions made her this way.

Mayuka Kondō (近藤 繭佳, Kondō Mayuka^?)

Voiced by: Kazusa Aranami

Shūsuke's classmate and class president, with a strong interest in Boy's Love magazines. When one of her magazines is torn up by Shūsuke during a mix up with one of his, she makes him her 'pet', having him purchase more explicit BL magazines and review them for an unbiased opinion, though she interprets this as having a shared interest. Despite Shūsuke's perverse belief that she may ask him to do something perverted at some point, she seems to be oblivious to this, appearing to treat him more as a boyfriend such as making him bentos and coming to wake him up for school. Recently it is shown she has strong feelings for Shūsuke because of his apparent acceptance of her BL magazines. She soon becomes attracted to Shūsuke's pink and sensitive nipples due to the fact she has never seen a naked man before, though despite him being her pet, she doesn't use this to her advantage.

01	"Wicked Usual Day of a Brother And Sister" "Ani to Imōto no Yokoshima na Nichijō" (兄と妹のヨコシマな日常)	January 9, 2011
Nao Takanashi has long been trying to tempt her brother, Shūsuke, into entering an immoral (i.e. incest) relationship with her, with Shūsuke barely being able to resist. Nao goes to great lengths for Shūsuke to think of her perversely by doing things such as letting him purposely look underneath her skirt (and once letting him see her completely naked) but then she always gets him into trouble afterward so as to make it look like Shūsuke is the immoral pervert. One day, while Nao searches through Shūsuke's room for his collection of porn magazines, she then finds a hidden family photo album and is surprised to find out that there are no childhood pictures of her in it. After Shūsuke was finished being scolded about his porn collection, Nao confronts her parents, Shūji and Nanaka, about the album. They then tell her the truth: 10 years prior to the story, a car accident killed Nao's real parents and left Nao with memory loss, so Shūsuke insisted that Shūji and Nanaka adopt her into their family where he vowed to care & look after her as his sister. Nao, curiously enough, is more shocked by the fact she and Shūsuke are not actually blood related. At that instance, Nao realizes that a possible intimate relationship with him would be acceptable. Nao then requests Shūji and Nanaka to keep the fact she learned the truth from Shūsuke so that they can retain their sibling status.
02	"Twintail, Attacking Brother and Sister" "Tsuintēru, Kyōdai o Shūgeki" (ツインテール、兄妹を襲撃)	January 16, 2011[4]

Iroha later comes to Shūsuke, reintroducing herself as his childhood friend and kisses him, proclaiming they are lovers due to games of Doctor they played when they were young. Shūsuke feels ashamed of his past perversion, throwing away all his porn and his perverted nature, which causes Nao to grow concerned. Meanwhile, Shūsuke becomes increasingly worried that Iroha seems to know everything about his private life, and later she blackmails him with threats of telling Nao about their games of Doctor.

Iroha tries to drag him somewhere else, but Nao manages to bail him out. Nao begins treating Shūsuke coldly, leading him to realize that she knew about his date with Iroha. When Iroha scares Shūsuke with the notion that she knows everything he's been doing (having been watching him through a telescope), Shūsuke rolls on the floor when Nao enters, getting a look at her panties which reawakens his normal perversion, much to Nao's delight.
04	"If My Little Sister Wore a Swimsuit" "Imōto ga Mizugi ni Kigaetara" (妹が水着にきがえたら)	January 31, 2011[4]

That night, when Shūsuke attempts to make an exchange with Mister X using a different BL magazine, with Nao and Iroha stalking him, he learns Mister X's true identity is that of his class rep, Mayuka Kondō. With the threat of his porn being shredded or shown to Nao, Shūsuke agrees to become Mayuka's pet, assuming there will be sexual requests involved. The requests start simple, such as buying her a drink or trying her bentō lunch. However, the next evening, Mayuka asks Shūsuke to buy her a more extreme BL magazine she's too embarrassed to buy herself.

When Shūsuke gets a report about him failing in all of his subjects, he then realizes that he has to take a follow-up exam or risk having to take summer classes. Believing that she was the cause of Shūsuke's grade for calling him out each night, Mayuka feels guilty and offers to help him study for an upcoming exam. But while they were studying, Nao and Iroha decide to intrude on them. As Mayuka tries to get Shūsuke to study, Nao and Iroha compete to try and catch his attention. After some time later, Iroha presents surprise tickets for everyone to go to a local pool park if he passed, which encourages Shūsuke enough to pass. At the pool, Shūsuke spends most of his time teaching Mayuka how to swim, leaving Nao and Iroha pretty jealous. During that time, Mayuka becomes amorously focused with Shusuke's nipples, having never seen a man naked before. As Nao tries to press Mayuka on her attraction to Shūsuke, he nearly drowns after Iroha forces him on a water slide, but is revived thanks to Mayuka's 'cardiac massage'.
