Sui

Kiri’s former girlfriend though she went out with him for less-than-romantic reasons. A very strong fighter who battles with something like a hula hoop. Since she enjoys fights, Sui decided to join the other two to face more challenging opponents. Besides that, very mischievous and always teasing Elraine… especially with her growing affection with Kiri. Also, Sui loves cherries… a lot.
