Sayuri Toudaiji

Sayuri is a girl in Minori's class who went to the same middle school as Takato. She lent Minori her yearbook so Minori could see how Takato looked then. Sayuri is also the older sister of Miyako Toudaiji in Kamikaze Kaitou Jeanne. She doesn't appear in the main story, only in a 4-koma in volume 3 where Miyako introduces her family.
