Height 155 cm (5'1") Kasumi Nakasu is one of thirteen members of the Nijigasaki High School Idol Club. She was a member of the original group and is a member of QU4RTZ, a unit under Nijigaku. She is a first year student and her image color is pastel yellow. As Kasumin loves all things cute, her unrivaled love for idols is strong and inspired. With the goal to dominate and become number one, she's a sore loser when she comes anything other than first place, even to the point of sabotage or cheating. She hates the nickname Kasukasu (かすかす) which roughly translates to "just barely" or "not quite", and gets in a bad mood when referred to with it. You'll often find her scheming or thinking up new ways to ensure her own victory; however, these plans often fail or aren't as devious as she thinks.
