Chisy is the description of the odd pairing between Chrissy and Chad. The two seem to get along well and were close friends early in the series. Later on Chad became a werewolf, and because werewolves are mortal enemies are vampires the two contstantly fought. Chrissy was over to get her mortal enimity to werewolves later on. After chad returned from his werewolf training, the two have got along very well, even going on one date that didn't go well because Selly spied on them and eventually attacked Chrissy. It doesn't seem like there is much hope in their relationship because Chad is commited to Courtney.
