With Yusuke dead, Kuwabara finds his life falling apart. Following a brawl with some thugs from a rival school, Kuwabara and his friends are forbidden from fighting for a week by a rat-toothed no-good teacher, Mr. Akashi. Not only that, but Kuwabara must also score over 50% on a test if Okubo, one of his friends, is to keep his after-school job and support his impoverished family. In order to help restore his life, Yusuke must give him an unseen helping hand.
