Sasuke serves as a loyal henchman within Yashichi’s (Yatch’s) circle, clad in distinctive purple attire and wielding a glockenspiel as his magical instrument—a nod to his role as a koto player in the series. His narrative threads include a quiet romantic pursuit of Yamane, a nimble ninja fairy allied with Momo Umezono. Introduced in episode 8, he actively participates in Yashichi’s schemes, navigating alliances and rivalries to advance the group’s objectives. His presence reinforces the faction’s tactical maneuvers while subtly complicating interpersonal dynamics among peers.
