In an era of chaos when the world was out of order and the Great Power ruled, the monk Xiangan brought an orphan from China to Japan. The orphan's name is Zitaro, and he has an amazing secret on his back. After being separated from Xiangan, the lonely and helpless Zitaro took his dog Himaru to Wankaku Temple in the country of Akaike, and met the mysterious swordsman "No Name" on the way. Zaitaro was hunted down and saved his life anonymously in a critical moment. Since then, the two have traveled together. Although the perverse ronin and the boy with a closed heart kept bumping into each other, they gradually became good friends.
The hunting organization led by Bai Luan still caught Zaitaro, and they began to prepare for some kind of ceremony. The blond swordsman "Luo Lang" is also a member of the hunting organization. Although he is obedient, he doesn't really care about the purpose of the organization. For him, it is the meaning of life to find an opponent that can rival him. The life and death duel between Luo Lang and Wuming kicked off.
