Just as Yakuto thought he'd found a way to reveal God's weakness, Vice Principal Bren catches the class Unawares with a cruel trap. Right as hope seems lost, the legendary White Dragon appears, giving Yakuto the power he needs to fight back, and maybe even turn the tables! But even if they win this battle, what deadly new challenge awaits back at the school?
