Fight Girl from Former Magical Girl, and the first adult girl in Mahjong Fight Girl. The kanji notation is ``Sanyuan・Great Love''.

She is the mother of Mitsumoto Cocoa, and also serves as the emperor's teacher and the mahjong club advisor.

She used to be a fight girl, but retired after marrying a man who was her instructor (coach) at the time.

After that, various things happened and I decided to return to mahjong fighting.

Furthermore, Dia's husband died when Cocoa was young (the reason for his death is unknown), and as a result, Daia herself is a widow.
