Fii

Fii is a Fairy who, like many other people, was drawn into the world of Arbatel by the magic of the Grimoire and was a student at the Grimoire High School for a time. She makes their debut in Chapter 78.

Appearance
Fii is a young girl with fair skin, pointy ears and hair that is braided into a long braid. As a Fairy, Fii's most notable characteristic is her small size, being only the size of a human's head. She has a pair of dragonfly-like wings on her back.

During her stay in the Grimoire, Fii wears the usual school uniform, consisting of a seifuku with a plaid skirt. She also wears a pearl necklace on her right wrist and a bracelet on her left wrist.

Personality
Fii is very friendly and shy. She has certain complexes about her small voice, probably because even the other Fairies often tell her that they can't hear her. Fii also expressed embarrassment when her boyfriend revealed that he bought the super high power hearing aid in order to hear her voice, which caused her heartbeat to quicken.

As revealed in her future dreams in Chapter 80, Fii later wants to develop and sell a miniature speakers for Fairies, as well as train herself to speak louder. This shows that Fii wants to overcome her complexes and support her people to make their lives in human society easier for them.
