Nakada Shizuki

The daughter of the chairman of the school, who is a senior student of the protagonist, and the younger sister of twins.
She is an old-fashioned, talented and talented honor student who loves her elder sister. It is rumored that the man approaching Shiina has been eliminated by Shizuki invisible.
She is the Vice President of the Student Council, ostensibly supporting the president's elder sister, but she is in control of Council.

Her names can be read as "Nakadashi zuki" (lit. "I like intravaginal ejaculation"), so they have the nickname "Nakada-sisters", but when she calls her, she gets angry.

"Don't call me NAKADASHI!"
