A ninja said to have lived in the ruined Bariura Empire. There was an incident where this man in a strange outfit suddenly appeared in the empire. A rumor spread that this strange person, known as a shinobi, had come from another world. However, afterwards, almost no one saw him again. Later, scholars surmised that this was because of his pride and dislike for standing out.
