I'll Make a Habit of It!
(超くせになりそう, Chō Kuse ni Narisō
?) is a comedic anime series about an idol singer/martial artist and the chaos that results from her efforts to have a life and love beyond her singing career. It aired as part of the anthology program Eisei Anime Gekijō which was broadcast on NHK. It is known as "the shōjo Ranma" in some fan circles[original research?
] due to the amount of time the heroine spends badly disguised as a boy.
Nagisa Shiratori is the heir to a judo training hall that has fallen on such hard times that their only pupils are animals from a nearby wildlife park. In a desperate bit to save her heritage, she reveals that she is going to go out into the world as an idol singer and find "strong men" to join her school. The first part of her plan succeeds beyond her wildest dreams: she is almost instantly elevated to the status of Japan's top idol despite an utter lack of anything even remotely resembling musical talent. Yet this dooms the second part of her plan, because her fame and schedule prevent her from finding the disciples she seeks.
So Nagisa horrifies her manager by chopping off her trademark pigtails and enrolling at one of the worst schools in Tokyo as a boy, under her given name of Nagisa Ootori (Shiratori is a stage name). There she runs into the toughest gang at the school, and after she soundly beats them they (believing her to be a man) recruit her to help them confront a gang from a rival school. Unfortunately, when she sees the leader of the rival gang, a handsome boy named Nosaka-kun, she instantly falls madly in love with him. Before the fight can begin, Nagisa is whisked away to a record signing, where she encounters Nosaka again, who is so utterly smitten with Nagisa Shiratori that he proposes marriage on the spot.
The next day the disguised Nagisa fights an inconclusive duel with Nosaka that ends in a stalemate, and with Nosaka declaring her a worthy foe he looks forward to fighting again. He later reveals to the female Nagisa that he too in on a quest to recruit disciples for a failing martial arts school, and is meeting with a similar lack of success. The next day, in their final confrontation, Nosaka discovers Nagisa's secret due to an ill-placed grab maneuver. Declaring he would rather love Nagisa than fight her, he agrees to keep her secret and they run off, with the school toughs and both their disapproving fathers in hot pursuit.
After that, Nagisa continues her double life, showing up at school some of the time when her manager cannot force her to attend to her idol responsibilities. Meanwhile, the world she lives in gets weirder and weirder, as more and more bizarre things happen in her proximity.
