Oh, okay. I was kinda hoping you got the idea from Rave Master since there's a race called the oni in that series. And just in case you didn't know, the person who created Rave Master also created Fairy Tail. So I was thinking that you were referencing those oni from that series. But what influenced you for the idea still sounds cool.

The creator of Rave Master got the Oni from Japanese legends, so it all comes full circle.
