Hina's friend and classmate. She's a model student and sits next to Hina in class, which caused her to start caring for Hina unintentionally.
When Hina was looking for Nitta, Hitomi was forced to help her. While waiting for Hina at Utako's Bar "Little Song", a regular customer at the bar started teaching her how to mix cocktails, revealing her talent (in doing actually everything). After that, Utako took a photo of her in bartender uniform and threatening Hitomi to work for her if she doesn't want the photo to be leaked. Now Hitomi jobs part-time at the bar every weekend.
After the time skip Hitomi started her own consulting company.
By the end of the manga Hitomi is the richest person in the world with a net worth of over 500 billion dollars.
