EdgyHeads spirit... His will to keep living was too strong, so he became a "Living Ghost".
He seems to not remember much about his past life... He has gotten amnesia after the powerful blows dealt by Eggy.
He doesn't speak much, only when he wants to.
He seems to be friendly with Ghostie, and will help and take care of her sometimes.
Be careful about talking or asking about his past life, because certain names or words will affect him, and Collecter fears the wrong sentence might make his memories come back.
