Aishia

Summary
Aishia is Rio's contract spirit, she has been contracted with Rio since the start or the novel and at the time Haruto's memories awaken, he hears Aishia's voice when he was in a crisis. She is a high-rank spirit which is incredibly rare. Aishia was the one who taught Rio spirit arts before Seirei no Tami.

Aishia spent the 3 preludes arc mostly by sleeping and occasionally her voice sounds to help Rio. Aishia wakes up in Rio's bed when she manifested. This was a few days before she gave Rio instructions on where Miharu and the rest were.

Appearance
Aishia is stated many times in the story as the most beautiful female in the series. She has a very divine look as said by Rio seeming almost artificial in a way, her beauty leaving a cold and fleeting impression. Aishia has extremely long peach-coloured hair reaching down her waist and gem-like eyes of the same colour.

Personality
Aisia is a caring and curious girl. She is devoted to Rio and will always accept him. She always wants to try living the same as humans do, eating good food, taking a bath, and wearing a cute dress. Though she's pretty blunt with her words, she has a weak expression. Almost expressionless most of the time, and she speaks in a monotone intonation.

According to Dryas, it's unnatural for Aishia to shown lack of expression as a spirit's personality should mature and when they reach high-class humanoid spirit. They should already have full personality, yet although already a humanoid spirit, Aishia is like a Medium class spirit mental wise, unless, being an expressionless character is indeed her personality. Also, when she manifested she had no memories aside from knowing all about Rio.
