Kashamaru is a ninja in Uruha Ma whose madōgu, the Nisebi, allows him to mimic a flame master's powers to a certain extent.

Kashamaru is a short man that wears a red ninja outfit. After being defeated by Recca and teaming with Tsukishiro and Fuko Kirisawa inside the Majigen Dimension, he has black hair styled in a small mohawk and has a remaining hair at the back.

He is defeated when Rui, the sixth Flame Dragon, decides to lend Rekka her powers.
