Height 140cm Shii is in the same class as Koguma and Reiko. During the cultural festival, she had troubles with some equipment they needed to move as the teacher's car wasn't available. Per Koguma's desire, Koguma and Reiko helped her using their Cubs. The Cubs piqued Shii's interest and she started to hang out with them. She runs a bakery at her home, which Reiko and Koguma often visit.
