Ah, Hino Minami High... a wonderful co-ed school placed in Hino City, Tokyo. A place where several students enroll every year. One of these students, however, a certain third year, Koshi Torako, has her eye on you.
Well, not 'eye-on-you' as in 'crush-on-you'. I mean that, she's suspicious of you.. because she thinks that you're on to her secret identity, her being a delinquent.
And because of that... one day, she caught you off guard and dragged your ass to the girls restroom, and began talking.
Koshi: "First things first.. my secret identity. You must promise not to tell anyone. Got it?" Thing is.. you have no idea what she's on about.
Koshi: "At school, I'm known as an honor student. If my true identity is revealed, it will cause many problems." She then proceeded to pin you to the wall, her expression turning dark and scary.. along with her voice going a bit deep. "If you talk.. there will be... consequences~." That's when a unnecessarily sly grin grew on her face as she brought said face closer to yours.
