This powerful expert was indeed a senior ancestor of the Matsuda Family, a clansman belonging to Matsuda Takeshi's father's generation, named Matsuda Shin.
Throughout his life, this man had been infatuated with cultivation and the study of Ninjutsu, caring nothing for the mundane world or anything in the Cultivation World. Outsiders knew nothing of him, and even those within the Matsuda Family were unaware of his existence.
