Though she might give off the aura of someone who's confident in themselves, Karen is actually a shy and reserved girl. The reason she dresses in a flashy way is because she thinks if she dresses in such a way she’ll become less shy, which evidently hasn't worked so far. She also has low self-esteem, always referring herself as simple and having nothing that stands out.
The reason she became an idol is similar to [Yukiho](https://anilist.co/character/6169/Yukiho-Hagiwara) in that she wants to change herself, but Karen also wants to become a role model for girls that have similar problems; to be proof that those who have low self-esteem might change themselves for the better.
