Midori acts as a "professional victim" in a business that is run by her partner Adamas where anyone that can defeat her will win a reward. She was once a PK whose skill was so great even Sakaki and a band of over 20 followers were no match against her,but gave up PKing after many meetings with Adamas. However, she is more famously known as the first person to survive an attack from Tri-Edge(Azure Flame Kite) whom she wishes to meet again,but unlike Haseo she has no ill will towards him.
