Momiji Mochizuki (
Momiji has neck-length red hair that has some parts tied on the left side by a black ribbon with bangs hanging on the right side, blue eyes and a rather busty body that is almost opposite to Aoba Suzukaze in just about every way from physique to personality.
In contrast to Aoba Suzukaze, Momiji is usually a quiet, solemn and stoic girl, to the point that jokes tend to go over her head. Unlike Hifumi Takimoto, Momiji isn't afraid of talking to people as she just views it as mostly unnecessary. However, she loves to eat and tends to eat large meals. She takes her rivalry with Aoba seriously, but she can be a bit of a slob when at home.
Momiji and Tsubame Narumi grew up in Hokkaido where she is aware of Tsubame's family dispute regarding her entering the gaming industry. It is unknown if she played a part in convincing them to allow Tsubame to join Eagle Jump.
- The name Momiji means "autumn color leaves" or "leaves turning red" (紅葉), which is similar to Aoba, which means "Blue/Green Leaves".
- Momiji's surname Mochizuki means "wish, desire" (望) (mochi) and "moon" (月) (tsuki/zuki).
- It can also mean "full moon".
- Although Momiji officially appears in Volume 6 of the manga, there is a glimpse of her on Volume 4 Chapter 51.
- Momiji joined at the same time as Tsubame Narumi.
