Aerial

Aerial or Airy is the first Spirit summoned by Taichi Nishimura and becoming one of the main characters of the Isekai Cheat Magician series. The Queen of Wind spirits who becomes bonded to Taichi. Originally she introduces herself as a simple Wind spirit named Aerial, but as Taichi's power rises, she finally evolves back into her original form, Sylpheed (Sylphy) her true identity.

Aerial has platinum green hair with teal colored eyes and pointed ears similar to an elf. She is shown to be wrapped in a green hagoromo like sash with four feathered wings sprouting from and wing like accessories in her hair and three diamond markings on both of her legs. She generally takes on the form of a young female fairy.

Personality
Aerial is shown to be a very loving and caring spirit with a strong sense of duty and loyalty, despite the fact that she wished Tachi could have summoned her sooner so that she could help him, she could not disobey the conditions needed in order to summon her and feels both sad and regretful that she could not aid him when he needed it most in the beginning. Since her summoning she has done everything she can to be both helpful and useful to Tachi and is shown to be very loyal and protective of him, telling Tachi that she would never abandon him.

History
Like all other spirits, they are beings to be considered to be above humans and dragons themselves. They cannot be seen through the naked eye, nor their voices are heard by regular humans unless they are of high magical aptitude.

Her relationship with Taichi was already reached before his summoning due to his pre-discovered magic capacity. Before Taichi's awakening as a summoner, she maintains telepathic communication with Taichi until being cornered by Cassim's Red Wolf where she briefly lends Taichi her power. It wasn't until Anastasia's death that Taichi acknowledges his unique power and formally pact a contract with Airy.

During the mid-climax battle outside the capital, she evolves, one of the Four Great Spirits, Queen of Wind.
