When he was a child, he was more active than his brother Ace. But then he developed an earworm that constantly plays sleepy music, then soon enough he started to become more sleepy, even at times when he doesn't even feel sleepy. However just by wearing headphones and playing all the songs stuck in his head, he's back to being a chaotic child, though this doesn't last long, for the music can just come back when it needs to.
