Sakurako and Shotaro accompany Isozaki after he learns that one of his former students, Hitoe Madoka, has gone missing. After looking through Hitoe's room and getting some additional clues from Yuriko, the group investigate the residence of Hitoe's friend, Minami, where they find a painting similar to one found in Hitoe's room. Finding Minami, who came to detest Hitoe for allegedly stealing away the painter she admired, Hanabusa, Sakurako takes her back to her place to give her a proper meal, unaware of the peculiar markings on her back.
