Naomi Fujimaki (藤巻 直美, Fujimaki Naomi) is a student in 9th Grade Class 3 in 1998.

Naomi is a tannish girl with light brown hair and greenish-grey eyes.

She is only ever seen wearing the school standard female uniform.

Naomi seems to be a sociable and kind person who is a bit tomboyish and is good friends with Haruka Etou and Megumi Tatara.

Naomi made her debut in "Rough Sketch". She wasn't a major fixture of Class 3-3, often staying in the background, though she was present most days.

Naomi was in class when Mr. Kubodera brought a mysterious black bag to class in "Sphere Joint", though she probably wished she hadn't when he removed a knife and violently committed suicide in front of the class. Naomi, along with most of her peers, was terrified by this event, fleeing in terror with the rest. Naomi may have taken the events that day especially hard, as she wasn't seen very often thereafter, and didn't attend the class trip, which probably saved her life.
