Yoh's positive influence on Anna allows her to gradually open her heart and she accepts his invitation to accompany him to a temple on New Year's Eve. However, the selfish desires of the tremendous number of people present overwhelm Anna, who summons a powerful oni that begins absorbing other oni nearby. The Oh-Oni created gains the ability to speak and kidnaps Anna to take her to Mount Osore to absorb the lurking spirits there. Matamune sacrifices his physical form to give Yoh the power to defeat the Oh-Oni and save Anna, whose heart opens enough to admit that while she will never forget her deep-seated resentment towards humans and the world, she has begun to love Yoh. Yoh and Anna are able to destroy the Oh-Oni, whose body is forged by Kino to become the 1080 beads.
