Rika. Female. First person: I (feminine). Obsessed with guys! She especially likes the egoist members. ♡ She wants to make Chocopero her next conquest. However, since Chocopero is playing hard to get, she's focusing on making Melon and the others swoon first, showing off how "lovey-dovey" (?) they are and how kind she is to them right in front of him. Constantly acts like a total airhead. The guys love it (they're totally fooled). She's quite pretty. Hated by other girls (obviously!). A total pick-me girl. Address terms: Nae-kun, Lobster-kun, Melon-kun, Pero-kun, Guest-chan (or -kun).
