Haruchiyo Sanzu/Synopsis

History
Haruchiyo was born as the middle child of the Akashi family, but he later cut ties with his siblings. Starting at a young age, Takeomi, his older brother, would make him responsible for their younger sister's doings and scold him for neglecting Senju's upbringing. Haruchiyo later came to despise this treatment, as well as Senju for frequently victimizing him in her mistakes. When Senju blamed Haruchiyo for destroying Mikey's beloved airplane figure, Haruchiyo was physically attacked by Mikey, which earned him permanent scarring at the corners of his mouth.

Tenjiku Arc
Haruchiyo visits Takemichi Hanagaki's residence with Yasuhiro Muto and the rest of the Fifth Division to restrain him in suspicion of betrayal. He later assists Mucho alone during the confrontation between the First Division members at a private warehouse.
