Kana Arima

An actress who was called a prodigy child. She has a rather stubborn personality yet an empathic side to her. She easily succumbs to pressure and while she does put up a front to others, she has very self-deprecating thoughts when it comes to her abilities. She's an honest and earnest person, who is very diligent and persistent even in the roughest of times. Also, she tends to place all responsibility on herself when it comes to others as she is the one who has the most experience in the show business world. She also hates bell peppers.

After the events of the Sweet Today Drama adaptation, she secretly develops a crush for Aquamarine.

She longs for someone to look at her for who she is now and praise her efforts, someone to say that its okay for her to be here. And after the new B-Komachi's first concert, that person becomes Aquamarine after he waves her respected colored glow stick. Only reinforcing Kana's resolve to make Aquamarine fall for her.
