And if you collect 1000 "Evil Coins" that you can get by doing bad things, you can return to the demon world. As a result, Ebiru and the others plan various evil deeds using the beasts that come out of Gachademon machines, but... The first collection comically depicts the turmoil caused by Shotaro, who has become close to the human world, and Ebiru and others.

Papa Ebiru, who was the devil in charge in 1999, was sent to the human world because he could not destroy the human race. Ebiru-kun and his friends do a lot of bad things and can't go back to hell unless they accumulate 1000 Evil Coins. ? A cute baby devil, a strange demon beast, and even a sexy girl! !
