This is a battle of gravity fighters. Kat uses gravity to amp up her physical abilities and move at super speeds while Haiji usually uses it more for projectiles. Although Haiji can use it physically as well and was even able to lift an entire chunk of a building. He just seems to be able to use it at a much higher level than what we’ve seen Kat do. While she may be able to put up a decent fight at first, the match is over once Haiji uses his Hungry Joker form. Haiji (Hungry Joker) wins.
