アイ

Ai was Forbesii's first fiance. In the main timeline, they break their engagement and Forbesii marries Sage instead.

Ai is a real fair lady and may be a part of the Royal Family of the Demon World. She is well-educated, graceful and gentle and has always been seen smiling sweetly. Her speech, thoughts and actions can be considered 'Big-Sisterly'. She often refers to herself as "Ai-Onee San" towards Rin. 
If the player decides to restore the original timeline, then Ai will be a potential ******e who can be romanced with Rin in addition to having Nerine in the epilogue. In the epilogue of her route, she becomes Rin's second simultaneous lover after waiting for 20 years and reuniting with Rin in the human world./
