K.C. is a master-class thief who uses the master class item invisibility bandana. In game she is in the fallen angels along with Julie and in real life the two of them are the Lovely angels, the well known pop idols Jin-Mee and Gina. They originally hold a grudge against Team Triple Threat, since they captured them and forced them to sell off kisses and hugs to random people for the economic benefit of the trio. They helped out in the demon invasion arc, and later she is seen following Ban after her partner is killed.
