月島 沙織

She is the student council president of Seiou Academy and the only daughter of the chairman of the Tsukishima Group, a world-famous large corporation. 

She is attractive, intelligent, proper, good-natured, and good with people. She is considered the ideal "oujo-sama" and is popular among students of both schools, regardless of gender.

However, in reality, she is a bit sloppy and troublesome. She'll sometimes lie down and eat sweets when no one's looking.

"Ren-kun, you always go along with my selfishness, don't you?"
