Ass Catchem wears a white and pink tracksuit consisting of a tank top and shorts.


Judgment: 2018-2019[]

Ass Catchem gropes Tsukino Saotome's buttocks and tells her she would look nice with small hair, prompting Yosuke Saotome to seek Takayuki Yagami's help. Yosuke acts as bait, and Ass Catchem gropes him, mistaking him for Tsukino and assuming she took his advice. Yagami chases him down and beats him in a fight, but Ass Catchem powers himself back up by remembering his most recent groping, only for it to backfire by demoralizing him when Yagami points out he enjoyed groping a man. He is arrested thereafter.

Lost Judgment: 2021-2022[]

Ass Catchem escape from prison with his fellow Twisted Trio members as well as Giant Impact using his newfound disguise abilities. He recruits people for creating a pervert kingdom and gropes a woman while wearing a Kamulop costume. When the Filthy Four announce their plans, Yagami raids the abandoned love hotel they are staying at and defeats them all before once again turning them to the police.


  • His localized name is a reference to Ash Ketchum from the Pokémon franchise.
  • The kanji in the middle of his shirt, 本山 (Motoyama), is a name, though whether it is the name of a brand or his real name is unclear.
