Buyuden is a manga written and illustrated by MITSUDA Takuya.

Plot
Take Isamu is the best at everything he does at school, from looks and smarts, to his luck with girls and his abilities as an athlete. He considers himself to be in the top percent of his age group and is incredibly bored with interacting with the so called "normal people". That is until a new student, Kaname Moka, transfers into his school and, as she is quite pretty, Isamu asks her out. Moka mishears what he says and thinks he wants to challenge her to a fight, as she grew up on boxing. Determined to win her heart, Isamu decides to become a great boxer, with the help of new friends and allies he and Moka meet along the way.
