A new OC xD
He's a boy possessed by a Oni spirit who wants to defeat the Big Oni ( King oni ) So that he doesn't need to die anymore or suffer in the underworld, but he's already dead and The Big Oni has psychical body so Ifrit ( the oni ) escapes to our world looking for a body.... That's all for now :P
Ps*
When Ifrit ( the oni ) and the boy he posses transforms to the Oni form they kind of become a new person ,they don't stop existing , but the a no more two souls and yes one , sometimes the oni form refer to himself as "we" .
