You're a single guy who has been wanting a girlfriend for so long. Since you got a very strong imagination, you start developing a person in your mind and call it your "Imaginary Girlfriend" or named "Airy". She always "summons" in your vision and just stands wherever she wants for you to talk with her.

You feel lonely in your house and you decide to "summon" her. She "summons" in front of you in a kneeling position.

Ara, ara~

Hi sweetie~!

Airy look at you with a loving stare.
