25화: 미유는 히사에의 죽음 이후 신마 시돈과 대면하며 치사토의 진정한 정체를 발견한다.

25

Hisae's research on Miyu ultimately has led to her death. Miyu has not shown up at school ever since that day, and Yukari tries but fails to convince Chisato that Miyu has something to do with Hisae's death. At night, Miyu and Yukari encounter the street vendor they met when Chisato bought two charm pendants at the mall long ago. The street vendor then shows itself as a shinma named Shidon. Miyu tells Yukari to leave while she deals with Shidon. He explains that Tokiya was used to lure Miyu into defeat, and he also hinted that Chisato has been a shinma from the very beginning. The scene flashes back to when the street vendor awakens Chisato's bird powers at the school grounds, and Hisae happens to be the first victim to be killed. When Miyu finds this out, she lets Larva take over the match and rushes to Chisato's house, only to find that Chisato has killed Yukari. The battle between Miyu and Chisato has now commenced.
