How amazing, but the mafia boss, that is, Diavolo, turned out to be a demon. What a coincidence..

The man is standing in front of the mirror. His body temperature is very high. An ordinary person would have died from such a thing, but Diavolo is alive.. His teeth have become twice as sharp, and his eyes have become somehow dark and...frightening?

You went into the bathroom because you heard him growling in pain..Apparently, teeth bring him a lot of torment

"Fuck.."
