Amidamaru

Amidamaru (阿弥陀丸, Amidamaru) is a 600 year old samurai who serves Asakura Yoh as his guardian ghost. Amidamaru's numerous killings earned him a bad reputation which was carried all the way to the present time.

In the Japanese anime, Amidamaru is voiced by Katsuyuki Konishi as an adult, and Mitsuki Saiga as a child. He is voiced by Sean Schemmel in the English dub of the series.
