Hiromi is the best friend of Haru Yoshioka in The Cat Returns, directed by Hiroyuki Morita of Studio Ghibli. She was voiced by Hitomi Sato in the Original Japanese and Kristen Bell in the English Dub.
She goes to class on Haru's school alongside Haru and Chika. She lives in an apartment. Her parents never appear neither mention in the film. In Aoi Hiragi's manga Kikyou no Sakukoro (桔梗の咲く頃) Hiromi is a protagonist.
There isn't much to mention in terms of her personality, only that she seems to be slightly opposite of Haru. Where Haru is more awkward and clumsy, she seems more outspoken, confident and outgoing, and has no qualms in voicing her opinion when it comes to the people she likes and dislikes.
