Tenjho Tenge is about Souichiro and Bob want to rule their new school, but just as they begin cracking heads, their plan is shot to hell. First there's the Natsume sisters and their Juuken Club. If the older sister, Maya, isn't kicking their ass, then the younger sister, Aya, is trying to force feed Souichiro and make him her husband.
Then there's the Student Executive Council that sends executioners to educate anyone who questions the council's authority! Souichiro and Bob end up joining the Juuken Club so that they will both become strong enough to face the Executive Council.
