Appare! Tenka Gomen

The famous Ooedo Gakuen is the home of students who will become the future leaders of Nihon. It is a mix of traditional setting and modern technology where students walk around with swords. Yakumo recently transferred to the school and he is very satisfied with the school life. There is a school rule that students must earn money to support their own expenses, in order to learn how to be independent. He helps out at a nearby tea shop, but soon after he starts some delinquents pick on him. A girl on a white horse, Yoshine, appears and dispatches them after a lively swordfight. Touched by her pure sense of justice, he ends up helping her in her quest to change the world.
