Ai

She is introduced as a main character in ''[http://en.wikipedia.org/wiki/Tick%21_Tack%21 Tick! Tack!]''.

Ai is first introduced in ''Tick! Tack!'', where she is Forbesii's fiance. In the main timeline, they break their engagement and Forbesii marries Sage instead, but the timeline may be changed so that Ai does marry Forbesii and becomes the mother of the alternate, red-haired Nerine.

At first, Ai was thought to be Nerine's mother since Nerine's hair, grace and measurements matched with that of Ai more than that of Sage, it's no surprise that the group have misunderstood her as Nerine's mother.

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 (even when she is sad and sobbing). Her speech, thoughts and actions can be considered 'Big-Sisterly'. She often refers to herself as 'Ai-Onee San (translated as Big sister Ai)' towards Rin. Her speech pattern even seems 'Big-Sisterly', even to those who seem to be older than she is e.g. Forbesii.

Ai has several 'over-leisurely' activities such as taking a bath (according to her, her average time in the bathroom is about 4 hours), or standing against the cool breeze at the mansion's balcony (according to her again, this is the way she thanks her fate that let her meet Forbesii).

Ai seemed to know the feeling of Forbesii and Sage toward each other, she often encourages Sage to state her feelings, though it seemed more like a way of making fun of her. Although she loves Forbesii more than anyone else, she is still pleased to give in and allow him to free his heart to whomever he loved.

Ai (藍) is the Japanese word for Persicaria tinctoria, or the Japanese indigo. Since her name is written in katakana, it can also carry a secondary meaning of 'love' (愛).
