Ai Mikaze
The senpai of Syo Kurusu and Natsuki Shinomiya.
In the anime he’s in an idol quartet with Reiji, Ranmaru, and Camus called QUARTET NIGHT. Ai is very apt and hardworking. He often is the mediator when Camus and Ranmaru argue. Ai is strict with his teaching. His previous students quit after one month of training under him. He goes by, “If they have potential, raise them. If they don’t, drop them.” Ai calls everyone by their first names.
In Debut and the anime, it’s said that he’s an android (A.I. stands for Artificial Intelligence). Because of this, he isn’t able to fully understand human emotions.
He is a robot that was made by a professor, who loved his nephew dearly. He was built to be a replacement for the idol Kisaragi Aine. Kisaragi Aine was an idol who was fed up with being a singer, so he attempted to commit suicide by drowning himself in the ocean. However, his attempt turned out to be unsuccessful and he was later rescued, though he remained unconscious.
The professor, who also happened to be Aine’s uncle, wanted Aine to understand that the world wasn’t all bad, so he created the robot known as Mikaze Ai who was a carbon copy of Aine. In hopes that it would help Aine reawaken from his coma, he then linked their brain activity together so that Aine would experience whatever Ai felt.
