"Tank" Tetsu is a yakuza member affiliated with the Abegawa Tenchu Kai.


Tetsu is a middle-aged man with dark hair and a beard. He wears sunglasses and has a scar on his right cheek. as a member of the yakuza he wears a fancy light-colored jacket and is also seen wearing a scarf. His pants, like his jacket, are light-colored.


Tetsu is a hot-tempered individual who seems to enjoy drinking.



While enjoying sake in a bar, Tetsu complains about the fact that their organization has been categorized as an offical villainous organization and gets infuriated when he notices that Rojiya Yonenaga does not seem to be bothered at all about this. Rojiya then states that it does not matter to him because a man's way of life does not change from one day to another even if someone like All Might is watching. After agreeing with him Tetsu encourages him to drink more.

After they finished drinking Rojiya decides to take a manhole with him and Tetsu orders his subordinate to stand guard until the police arrive because no one is supposed to fall into the hole that was previously covered by the manhole.

One day the Tenchu Kai's headquaters are attacked by a single assailant, the vigilante Stendhal. The four present executives quickly activate their respective Quirks to battle the intruder. Tetsu, Haruhisa and Souji simultaneously attack Stendhal who is then forced to jump in order to dodge the barrage of attacks. Rojiya then proceeds to throw his manhole with a considerable amount of force at the vigilante. Stendhal, howewer, licks the blood samples of the four executives and thus paralyzes them with his quirk. He then quickly finishes them off with one single slash, killing them.[1]
