Akaishi, or Red, was the second in command of Kiyomasa's Gang and a member of the third division of the Tokyo Manji Gang. Red particularly enjoyed humiliating and hurting their "slaves", and his fate after abandoning Kiyomasa is unknown.
Red has average height and a slim build, though he often appeared smaller by hunching over towards his "slaves". His eyes and sadistic green are ofte, if not always, locked in an expression of unnerving sadism
Though all members of Kiyomasa's Gang are sadistic individuals, none of them take as much pleasure in humiliating their victims as Red. His position as the second in command means that he is subject only to Kiyomasa himself, which means that Red is loyal to him, praising his strength like the rest of the group.
However, after Kiyomasa is defeated by Takemichi Hanagaki after stabbing Draken, Red quickly turned on Kiyomasa, indicating that he is not to be trusted. Red is also proven to be a coward, fleeing from the sirens and abandoning the unconscious Kiyomasa behind.
