Dark seems to always have a run-in with women (Though he hates it). He seems to hate having the attention of women. He also has a club named after him. He also hates having women fall in love with him. Dark is also tormented by his father who wants Dark to be just like him. He then snapped and attacked Fuma in rage of hating perfection. But Roxas appeared and stopped Dark who ran off the Ashford Pond. He looked at himself in the river and saw Light thus activated his neass and started cutting himself. Kira came along and saw Dark hurting himself and try to stop him but it didn't work. He was then knocked out by Zoro and taken to Disney Castle. He awoke to see Kairi standing at the door of the room. He activated his neass and pointed his arm bone sword at her telling her to back away. But Kairi tries to comfort Dark and then Ichigo comes and Dark snaps at him blaming him for everything and throws the badge summon at him.
