Oniichan☆Control is a bi-monthly (formerly tri-monthly) manga by Yuna Kagesaki, the author of Karin.

Hirose Goushi has a huge sister complex. So huge, he moves from his home town to Tokyo to attend Myouzen University in order to escape it!

Three years later, Goushi's little sister Noa shows up and informs him that she's taking the Myouzen University entrance exam and that she will be moving in if she passed. Little does Goushi know, she has a similarly large (if not larger) brother complex.

Their neighbors are a female amateur manga artist (Takanashi) and an Otaku (Edo), who keeps to himself. Noa sees the manga artist as a threat and blackmails her to keep quiet Noa's secret crush on her brother. Takanashi has a crush on Edo but Edo doesn't like Takanashi because of artistic license of Edo's image in a certain genre of manga.

Tropes used in Oniichan☆Control include:

• Accidental Pervert: Invoked. Noa intentionally sets up situations where her brother will see her in various states of undress "accidentally."
• A-Cup Angst: Inverted with Takanashi who wishes she was flat chested.
• Beautiful All Along: Edo.
• Beta Couple: Takanashi and Edo
• Berserk Button: Noa in regards to any hint in her eyes (real or not) of another woman showing any sign of an interest in Goushi.
• Big Brother Attraction: Taken to the extreme, with a little sister actively trying to invoke Brother-Sister Incest.
  • More specifically, she's actively trying to make him lose his self-control and attack her.
• Bishonen: Edo when he loses his glasses, to the point that it's freaking out Noa.
• Bland-Name Product: Noa's Ipob.
• Blank White Eyes: Invoked by Takanashi when Noa threatens to upload an audio file of her masturbating if she tells her brother about her Yandere persona.
• Caught with Your Pants Down: Subverted, when Noa makes Takanashi listen to an erotic recording. Though confused at first, she soon realizes that its a recording of herself masturbating to Edo, turns out Noa bugged her room. In Noa's defense, she only brought it out after being called a pervert.
• Clingy Jealous Girl
• Comedic Sociopathy
• Creepy Child: While Noa's actually eighteen, her moeness and yandere traits give her this effect.
• Deliberately Cute Child: Noa plays up her innocence and cuteness in front of her brother. Playing in to her brother's image of her as a sweet and innocent sister to Tastes Like Diabetes levels is probably why she won't just make a move on him herself.
• Dysfunction Junction: All four of the residents are messed up.
• Even the Girls Want Her: Mai whenever she poses nude in art class
• Hypocritical Humor: Noa thinks to herself how disgusting it is that the mangaka and Otaku run away from reality by indulging themselves in 2D sexual fantasies... and then goes right on to thinking about how her and her brother will run away to an uninhabited island to live together since siblings can't get married.
• Knife Nut
• Manipulative Bitch: Noa is very good at manipulating people, especially her brother, Goushi.
• Moe
• Ms. Fanservice: Noa appears in the shower or in her underwear in almost every chapter. The only thing keeping it from being straight up Hentai is Noa being a Barbie doll downstairs and the lack of actual intercourse.
  • Mai as well, as befitting her role as The Vamp.
• Murder the Hypotenuse: Noa came close to doing this when she thought that Takanashi was in love with her brother.
• My Brother Is Off Limits. Noa threatens to kill neighbor girls and classmates who she even suspects have an interest in her brother.
• Nerds Are Sexy
• Noblewoman's Laugh: Ushikubo Mai.
• Not Distracted by the Sexy: Goushi whenever Mai poses nude. This is due to the fact that he is simply too absorbed in sketching Noa to take much notice.
• Not So Harmless
• Older Than They Look: Noa is 18. If your first reaction to this was "Bullshit!", we don't blame you.
• Otaku: Edo, who is obsessed with Eroge about young girls who have crushes on their big brothers. Guess who his new neighbor is?
• Shout-Out: When Takanashi recalls Edo's obsession with Lolicon manga, the first volumes of both Kodomo no Jikan and Hiiragi Shougakkou Renai Kurabu can be seen. ^{[dead link]}
  • This. I seem to vaguely remember a big fight in a popular manga between a frog, a slug, and a snake. Also, when Edo finds out about Noa's perversion he exclaims "Laputa existed!"
• Single-Target Sexuality: Goushi can only get aroused by the thought of his sister.
• Stalker Shrine: Goushi's room was basically one of these to Noa before she moved in with him.
• The Vamp: Ushikubo Mai. She only gets wet if she's in the process of breaking someone's heart, and she clearly enjoys every single minute of it.
  • Just to drive the point home, she's drawn with fangs at one point.
• Unresolved Sexual Tension
• Yandere: Noa, in case you didn't realize from the other trope descriptions.
• Yaoi Fangirl: Takanashi
  • Also Noa's old high school classmate, Keiko, who happens to be a fan of Takanashi's work.
