Saori is a member of the group Merm4id. Saori started her DJ career in high school, and due to her hardworking nature, she's built up a certain level of technique. She decided to become a DJ after listening to a remix made by a person who worked at the club FROLIC. Her pessimistic thinking held her back from DJing actively, even as a university student. Rika forced her to join the unit, but has made up her mind to change her mentality and achieve her goals. She is the one who always stops Rika and Marika's antics from getting out of hand (e.g. Saori scolding them for doting Saki too much).
