Haruchiyo Sanzu

Sanzu often appears as a background character throughout Tokyo Revengers. Sanzu was the former Vice-Captain of the 5th Division in Tokyo Manji Gang but later joined Bonten as Bonten's number 2.

Appearance
He has long white/blonde hair and long lashes. He is mostly shown wearing Tokyo Manji Gang's uniform with a black mask to cover his scars. As an adult, Sanzu has a long pink mullet and wears a purple pink suit. The Bonten tattoo is on his right forearm. He no longer wears a mask covering his face which reveals the two scars on both sides of the corner of his lips.

Personality
As a teen, Sanzu was a troublemaker who had a calm demeanor and didn’t talk much. He was extremely loyal and much nicer to those he follows and worships. However, it is later revealed that he is also quite manipulative and is exceptionally good at deceiving other people. As an adult, Sanzu seems to be more extroverted, blunt, and loud. He is ruthless and displays psychopathic tendencies. Sanzu is also shown to be on many drugs, which is believed to have played a big part in his insane behavior and personality change. To this day, Sanzu is still extremely loyal and holds great admiration towards Manjiro Sano. He will not hesitate to cruelly kill off any traitors without mercy nor remorse.
