Nana Baba is a giant but kind old woman who Gash met in Mochinoki Town. She quickly befriends him after the two have lunch together; and to pay her back for this kindness, Gash vows to help her to find her son (Tadashi)'s wife, Hiromi.

  ~!If Hiromi were not a good girl, the kind that wore cheap jewelry and short skirts, and was out to ruin her son's life, then she would feel a mother's wrath.
When she finally meets Hiromi face to face (with the help of Gash's bloodhound-like nose) she gives her her own wedding ring as a present and tells Hiromi to "Take care of her son". The two hug for a moment before Gash leaves.!~

Takamine Kiyomaro, a depressed don't-care-about-the-world guy, was suddenly given a little demon named Gash Bell to take care of. Little does he know that Gash is embroiled into an intense fight to see who is the ruler of the demon world. All of the demons have to pick a master on Earth and duke it out with other demons until one survives. Needless to say, Kiyomaro becomes Gash's master, and through their many battles, Kiyomaro learns the importance of friendship and courage.
