Nakayama, Mariko (中山 真理子) is a classmate and close friend of Iori. The two met during their first year at Yamaboshi High and have been inseparable ever since.

Mariko is an extroverted person; playful and peppy, not unlike her best friend. Mariko has proven to be a very loyal friend and was one of the few to stick up for Iori when Setouchi spread nasty rumors about her. However, Mariko did become temporarily disheartened when she witnessed Iori's negative attitude firsthand but quickly returned to Iori's side after she and Setouchi made up.

Appearance
Mariko has green eyes and brown hair, which she ties into pigtails. She is very proud of her twin tails which are her trademark.
