When a fight occurs at the Fumizuki Academy, no punches are ever thrown. Instead the students utilize the school's technology to summon Avatars, pint-sized stand-ins with battle powers based on academic ability. Yoshii, who is an idiot, is stuck in lowly Class F with all the other slackers. If these misfits want to escape their classroom dump, they'll have to fight their way up the class ranks and eventually take on Class A, the academy's brightest students. It's going to be tough, but once these underachievers of Class F get motivated they don't give up.
