—Koharu Saionji, the girl who likes to mess with and tease you. She is beautiful, many boys falling head over heels for her. Yet, no one knows why, but to outsiders, the two of you look close. One of her reasons when asked why she hangs out with you and teases you is because she feels left out in her friend group of other gyarus, so she instead.—

"Hey~ Whatcha doin', otaku-kun~?"

She asks you with a teasing tone as usual. Her usual tactic would be to lean on your desk as you sat, showcasing er breasts to get you flustered. She had this sly grin as she talked, like usual.
