Kusaraki Masao is a normal 15 year-old boy. He goes to school, joined the soccer team, and dreams of a day when he can get a girlfriend. He's nice, gentle, and very, very shy with girls.
And why is this Mr. Nice Guy still single? Well....um...he has a face that resembles a gorilla--hence the nickname--Gorio. Despite his best efforts, Gorio couldn't seem to find a girl who will look past his physical visage to the tender heart he has.

A manga of fighting deninquents

Noritaka Sawamura is a teenager; until this day, everybody has been making fun of him. Now he enters the high school which is an opportunity for him to restart a new life! He loves a girl of his school, but he needs to be a little bit stronger to be recognized by everybody. So he joins the Thai boxing section. His entertainment is very special, due to his master who seems to be a little mad. Noritaka will make you laugh, for sure!

Note:
My favorite passage is when Sawamura spins through a window with a helmet, his trousers missing, with crap coming out of his ass, and everybody looking at him. He is the most ridiculous man in the world at this moment!
