Dohran

A general named Tokugawa was entrusted with 13 angel swords to establish peace in Japan. After he founded a new dynasty, he was killed by his 12 commanders, each of whom possessed one of the 12 sacred swords. The thirteenth, known as Fire Phoenix, was given to Dohran, Tokugawa's son, who was described as naive. Time has passed, and now Dohran, posing as a traveler, is on a quest for revenge and aims to restore what he calls "the world of laughter."
