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.

Physical traits

 * Fairy Physiology:
 * Flight: Fii's insect-like wings allow her to fly.
 * Small voice: Due to her small size, Fairies have soft voices, but Fii's voice is unusually low even for her species, as even the other Fairies often can't hear her.
 * Petite physique: Because of their small size, Fairies have a very delicate build, making them more prone to injuries, such as being held too tightly by someine's hand.

Zoological Classification
Fairies (also known as Faerie, Fey or Fae) are a classification of Liminals that have been commonly described as miniature elf-like humanoids with bug-like wings that commune with nature or are otherwise skilled in magic and can fly.

Trivia

 * Although Fii's exact height is not known, she is currently the smallest character in the manga series.
