This girl has been drawn by several artists, unfortunately she doesnt have a name which makes her difficult to track. She's originally portrayed with sunglasses over her hair or some type of headgear, she's always drawn with her flower hair ornament. She looks fun :D

EDIT: Very similiar to ntw-20_(girls'_frontline) bikini
