Mintsuchi (ミンツチ Minstuchi) is a yōkai.
Due to the fifth anime adaptation's sudden cancellation at 100 episodes, he is among the 23 Yōkai Warriors that were not revealed aside from the movie.
There are sightings in and day high of Kushiro River. He lives in the water just like the kappa.
Minstuchi's name is hypothesized to be originated in Mizuchi which means "Water Spirit/God/Serpent" where Kappa was originally called Kahaku, the "River Spirit/God", and Mizuki noted the connections in the etymology of these beings.
