(I personally don't like Ururaka that much, so if I leave anything out then please tell me and I'll fix it right away:))

Ochaco Ururaka is the main female lead of the show, she is friends with midoriya and has a rather obvious crush on him. She comes from  a poor family, so she uses her quirk (antigravity) to become a hero and get more money for her parents.

Her voice is rather high pitched and sweet.
