"A Yo-kai that has been trusted to be escorted as part of a entourage of Nuraihyon. His loyalty to try and protect Nuraihyon is so absolute, even if it means throwing away his life. Nekokiyo was his childhood friend that was found in a luck shrine, he was lucky to have good memories with him."
In his Boss Yo-kai form he has a much more muscular body, and his robe pulled off of his upper section. He has a thick tuft of fur below his neck as well as a longer tail, huge claws, and his long, drooling tongue is constantly hanging out.
In Yo-kai Watch Busters, Inumaro -as Inumaroderon- specializes in melee and claw attacks. If Nurarihyon is defeated before Inumaro or Nekokiyo during the battle, one of them will sacrifice themselves to revive him.
