Rin, a disciple of King Harrid/Mr. Treasure that had been overseeing the ruins where the Gomisuteba were sealed. However, over the centuries she can come to think of conflict as meaningless and began to slack in her duties. Not long after her master's defeat, she left the ruins but wound up freeing some excess dark energy in the process which found its way into Usami's house and set everything into motion.

Deciding the endless battles would not end Rin decided to take personal action, disguising herself and observing the current conflict from afar. As both the Koma Cards and the Ibis Empire were made as a byproduct of the dark energy she could therefore use her powers as a gaurdian to blunt their power. Eventually she wound up following the exact same path Harrid did and decided the only way war would ever end is if those who spread it ceased to exist. To that end, she tried to "purify" the world but was eventually stopped by the Precure who managed to calm her and, with her duty finished, finally allowed her spirit to pass on.
