Ena is a Shikabane that resembles a young man wearing a green robe, glasses and a giant bow on his head.
When Ena was human, he was a skilled artist. However, he committed suicide because he didn't have "true beauty." It's revealed that his body is actually made from different corpses. Besides his curse, he has a metal ball that can grind things into dust. Sadahiro barely escaped the ball, and where he was standing before was a huge crater of smoke and ash. Akasha once commented on Ena being a theatrical performer.
