late night at school to tell him something. At their meeting, Kaori informs Yuichi that Shiori does not have very long left to live, and that by her next birthday, Shiori may die. Kaori tells him that the reason she does not want to get close with Shiori is that she does not want to feel the intense pain that will result from Shiori's death.

Sayuri cares very deeply about Mai, as it shows since they not only hang out together constantly, but Sayuri will get worried if Mai is in trouble; she also never forgets Mai's birthday. Initially, she is completely ignorant about the demons but even though some begin to target her near the end of Mai's story, she stubbornly stays by Mai's side. Sayuri, as with Ayu and Makoto, has a
