Rena "Black Princess" Kuroyuki

About

Rena is Kanna's younger Sister and a potential Successor for the Head of the Oni-clan, if she can gain Setsuna's Heart. She talks only with her exchange diary and seems to have no problem's arguing with her sister. She fights with two katana (one white and black) which seem to have a purify effect against other oni and demon, and leave no harm to the possessed victim.
