Mamejirou resembles a small weasel/squirrel with white and black fur, and a third eye on his forehead.
Mamejirou is shown to be talkative and snarky, the opposite of Saty. However, Mamejirou clearly cares a lot for Fuyumi, especially in her quest to keep from disappearing. Mamejiirou is often the blunt character, many times pointing out the others' strange behaviour.
Mamejirou is an outgoing, fun demon. He works as Saty's interpreter, since she herself cannot speak. He has one older brother, named Mametarou.
Like his partner, Mame has the "third-eye" ability, which allows him to see into a person's soul to determine whether they are okay to leave the demon world or not.
