Kana Arima

"I'm no prodigy. In fact, I believe I got to where I am today, because I ws able to realise that on my own early on. But that doesn't mean I won't try to live up to those expectations! even an unrivaled prodigy would die if you stabbed them! There are many ways to put up a fight. Ah, please edit that out though. I went overboard with my metaphor."

Kana Arima was a child prodigy and actress, a friend of Aquamarine and Ruby Hoshino, and the lead idol of the revived B-Komachi. Before this, she used to be a popular figure in the entertainment industry, one who always stole the show with her talent. Due to this, however, she started getting fewer jobs, and her fate ultimately being sealed as she grew up.

Despite her predicament, she never gave up on honing her talents. Even if the jobs she was able to land were B-grade at best, she would do what she could to gain back what was once lost. This gave her leeway to encounter Aqua and Ruby, which gave her opportunities to achieve success, and perhaps love?

Appearance
Kana is described as a cute girl having an innocent face. She has pinkish-red hair and eyes and shoulder-length hair with blunt bangs. Due to her occupation, she often wears a variety of outfits.

Personality
Kana is described as foul-mouthed and sharp-tongued which often leads her into trouble. Nonetheless, she is very empathetic, cheerful, confident, and weak to pressure. Her most evident trait is her diligence. She continued honing her acting even when she couldn't find work, as is her ability to raise or lower her quality of acting so she doesn't stand out. She also puts the quality of the product above everything else, even her reputation as an actor.

Story
Kana Arima was an actor since she was three years old, also known for being a prodigy. She was so confident in her craft that she belittled and underestimated Aqua's skills when they were children. This popularity spike faded away little by little as she grew up, being described as a one-hit-wonder. Even she is embarrassed by her own career with the type of jobs she took part in (most notably Pepper Workout.) Despite this, she continued working towards her goals; leading her to reunite with Aqua and Ruby, who participate in the same school.

Kana's knowledge and connections with the entertainment industry piqued the interest of Aqua, using her as one stepping-stone to get closer to his goals. After she and Aqua performed a grand finale for an adaptation of the manga "Sweet Today", she was called upon by the two siblings to ask if she could join the in-the-works revival of B-Komachi. Although initially against this, her weakness to pressure caved into their demands.

After the ending of LoveNow (a reality dating show), Aqua convinced Mem-Cho, one of the co-stars, to join the new B-Komachi. Now she, Ruby, and Kana act as the group's first three members. They made their first debut at JIF.

Relationships
Aquamarine Hoshino: she started acting with Aqua since she was 4 years old, when he acted with her in the first time, she was absolutely amazed, she met him again in high school and became friends with him, she also secretly developed romantic feelings for him.

Ruby Hoshino: she is Aqua's twin sister and also her partner, Ruby misheard her nickname "A Genius Child who would Flick a Crying Switch" into "A Genius Child who would Lick a Flying Snitch" which made Kana mad, Ruby and Kana later became partner idols. She dislikes Ruby's intense personality but also admired her for her bubbling personality and her ability to live as she wanted.

Kichijouji Yoriko: she is the author of "Sweet Today", the manga that was adapted into a TV-series with Kana as the female lead. As a fan of the manga, Kana admires her and was sad about the disappointing adaptation she was part of. Yoriko holds Kana in high regard for being one the two (second being Aqua) that saved the adaptation in her eyes and are on friendly terms.

Trivia

 * In Chapter 6 1st page we see an older Kana from the future, she said "A-kun" will get mad when she goes overboard with her metaphor, in the "Reality Dating Show" arc, people refer to Aqua as A-kun, and since she have a crush on Aqua this could be a hint that they get along in the future.
 * In Chapter 35 she admits she dislikes peppers.
