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 transformation, although this suspicion was ultimately proven wrong.

Appearance
Shii-Mii is a young woman with light- colored hair that is braided into a very long braid at the back of her head and hangs low in the front of her face, which mostly hides her large eyes. As a Silverfish Liminal, Shii-Mii has two thin antennae on her head and a total of four arms ending in three-fingered hands with chitinous claws. Her teeth are very pointy.

During her time in the grimoire, Shii-Mii wore the usual school uniform, consisting of a seifuku with a plaid skirt. She also wore a striped headband and two long black knee socks.

Skills & Traits

 * Silverfish Physiology:

Zoological Classification

Trivia

 * Although Shii-Mii is a second year student, it is unknown if her consciousness was actually absorbed by the grimoire two years ago. Since the cases of unconscious people caused by the grimoire were only known a short time before Chapter 74, it is also possible that Arbatel, using false memories from the enchanted school uniforms, led Shii-Mii to believe that two years had passed.
