An original character created by Ryo on December 19, 2008.
According to the artist, she was born from a trash can. Ryo got the trashcan pregnant just before he departed from this life. (And he was reincarnated as Raise.) Her loving adoptive father became mentally ill by his wife's death. Since then, Matsuri has been sexually molested. When she got raped by his grandson and lost her virginity, the father, who had a desire to deflower his adopted daughter, went totally insane and killed the grandson in rage. He placed an order for an artificial vagina in the shape of her vagina. And her currently bedridden father commanded her to use this device to treat his cock.
She revealed her secret super-slutty side only to Raise, who is her junior, best friend, and her real father.
