Shoujo Shounen Gakkyuudan

Haruka Nakatani, a boyish girl, transfers into an elementary school where her new class is strictly divided into two groups: girls and boys. But because of this unusual girl, who loves to play baseball, the class atmosphere is about to go through a change as well as Haruka herself…

This is a "Girl's Diary" of four very different girls' lives recorded in four short stories. 1. The O Girl: She tells him that they'll start as "just friends" but he seems to feel differently, telling her that she can't cheat on him?! 2. The S Girl: Always acting as the servant of the guy she likes, Rei-chan is starting to get fed up with this lifestyle. 3. The Girl in the Legend: Just as Tanoko has decided her fate as being only remembered for dying at her school, she meets the most popular guy, who seems to have a problem with being alone… 4. The Negative Girl: All the guys Hinako has dated have ended up in accidents, their lives being almost completely ruined while being with her. Hinako believes that her so-called "negative aura" isn't just coincidence.
