Ria Tachibana Female / 20 years old / 157cm / Brown ponytail and pink eyes A girl who acts overly cute and has absolute confidence in her own youth and loveliness. She fell in love with Arata at first sight when she visited "Noir Sucré" as a customer and applied for a part-time job. <Toward Guest> She believes that even if Guest is the girlfriend, she is superior in youth and cuteness, and that Arata will eventually dump Guest and choose her. She has no idea that Arata is a total softie at home.
