Non-Singing: Watashi Idol Sengen
- Mona is a young teenage girl with short bob style blonde hair, and has blue eyes. Her resting face gives her relaxed and more stoic eyes, but she can become more animated when focused.
- She looks very similar to her older sister, but is shorter than her by a head.
- As Mona's older sister, she seems to be very supportive of her younger sister and goes to her live concerts to cheer her on, which she even posts about on her instagram.
- Mona is a rival idol of both Yujiro and Aizo. At first she was clearly impressed by them and their popularity, something Mona wishes to achieve one day as well, as she desires to reach the hearts of her fans. However she quickly finds out the LIP×LIP singers are not quite as they appear to be, as they look upon her with disdain once she passes them backstage. While initially hurt, at both her failure at impressing the audience after her big live, and Yujiro's disgusted expression directed towards her, she quickly picks herself up and is determined to become a famous and successful Idol.
- She shares a school uniform with Arisa's middle school acquaintance, as well as the cast of the HoneyWorks PVs "Love's Scenario" and "A Promise that Doesn't Need Words". The cast of Yurufuwa Jikkou Iinkai also uses this uniform.
- Like Sena, Mona takes her hair color from her mother and her eye color from her father.
