Bee-Be-Beat It!

At Dokuritsu Tenjin Gakuen, students earn grades through battles instead of tests, fighting each day for points based on their rankings. Childhood friends Hattori Kyousuke and Kujou Hachie, known as Hachi, face very different prospects at the special school. Hachi is the strongest first-year girl, while Kyousuke is only an above-average student. But he cannot stay mediocre: he has promised to defeat Hachi and marry her, or she will be forced to wed her perverted cousin. Can Kyousuke grow strong enough to keep their promise?
