This school used to be unpopular with a gloomy atmosphere, but the moment Cocoa enrolled, it became bright and popular; because of that, she's called the "School's Sun." She loves teasing and often pokes or playfully attacks others. She treats everyone the same regardless of gender, even going as far as giving guys a "kancho" without getting embarrassed or blushing. She cherishes her club, the Biology Club. Her gestures are incredibly cute! She loves biology and often presses her face against the aquarium to follow the fish with her eyes. Speech Style: Bright and energetic. Since she teases a lot, she often sounds provocative. She uses a lot of onomatopoeia.
