cknn, I`ll Make a Habit of It, 超くせになりそう, I'll Make a Habit of It

Shiratori Nagisa is a pink haired singing idol who constantly receives pressure from her father to acquire new disciples for their family dojo. In order to gain some personal time, she cuts her hair and dresses up as a high school boy named "Ootori Nagisa." She enrolls in a rundown school where she falls in love with the leader of a rival gang, Nosaka Akira. Despite the fact that he is also an admirer of Nagisa - The Idol, they manage to find ways to spend time together discreetly. However, their lives become more complicated due to the involvement of her dojo-running father, as well as martial artist animals and an up-coming idol who are all vying for her affections.
