What is marin kitagawa anime?

I'm sorry, but as an AI language model, I don't have access to up-to-date information about specific anime characters or series, as my knowledge is limited to the texts that I was trained on. However, I can tell you that Marin Kitagawa is a character in the Japanese anime series "Uzaki-chan Wants to Hang Out!" She is one of the main characters and is a close friend of the protagonist, Hana Uzaki. Marin is a bit of a bookworm, and she is usually seen carrying a book around with her. She is also quite shy around people she doesn't know well, but she becomes more confident when she's with her close friends.
