Personality[]
Momoi wears his back hair into a ponytail and wears a gray kimono with a black happi over it. When Mugen confronts him, Momoi asks him if he wants to be his disciple, but Mugen wants to test his strength since there is a street killer trying to kill the best swordsmen throughout the area. Mugen easily beats his four disciples and Momoi pleads for his life, saying that he made up his nickname to make it seem like he was a tough guy.
He has a calm demeanor but is quite cowardly.
