Shii-Mii

Shii-Mii is a Silverfish girl who, like many other people, was drawn into the world of Arbatel by the magic of the Grimoire and is currently a second year student at the Grimoire High School. While Kimihito and his homestay girls were trying to discover Arbatel's true identity, Shii-Mii, due to her connection to books, was one of the three Liminal girls (alongside Maika and Aya) they suspected of being Arbatel in disguise, although this suspicion was ultimately proven wrong.
