Aishia

アイシア

Aishia is Rio's contract spirit as well as a high rank spirit, of which their existence are incredibly rare. She has been contracted with Rio since the start of the novel, during the time Haruto's memories awakened within Rio. Aishia was the one who taught Rio the Spirit Arts before he sets foot on Seirei no Tami after he fled from the Strahl region due to being framed for the Cliff incident. Prior to her awakening in her humanoid spirit form, Aishia spent the 3 preludes arc mostly by sleeping and residing within Rio. Rio would occasionally hear Aishia's voice briefly in a form of inner-monologue, where she tries to help and guide him out of his predicament. Aishia would eventually manifested herself and wakes up next to Rio on his bed after Rio successfully rescued Miharu, Aki and Masato from the slave traders.
