- A very popular idol, but encountered quite a number of difficulties. She's a first year in high school. Ever since a childhood accident at the beach with her father, she has the "eye-captivating" power. Because of her power, she was often alienated from people and had no friends, but once meeting the Mekakushi Dan, she regained her original, bright character. She has a peculiar sense in taste and fashion; it's common for her opinions to disagree with people. Unlike her brother, Shintaro, Momo doesn't do well at school and is always scolded by Kenjirou due to it. She is shown to only score 2 marks for a biology paper despite having attended two whole weeks of supplementary lessons. Her personality is pretty much the same as her brother's, as stated by Jin.
- Captivation: Momo's ability, known as "Eye Attention", can draw peoples' attention, regardless of their preferences in tastes or interests.
- Her favorite game is "Segare-ijiri" (Arrow Boy).
- She uses her eye power to catch people's attention during her performances.
- She is dreaming to be a pilot, with pig doll as her co-pilot.
- The Mekakushi Dan members, except Marry, Ene, and Shintaro, call her "Kisaragi".
- Although it's not a part of the Kagerou Project, Momo makes a small cameo in the PV for Jin's song "Your Eyes (キミノメヲ)".
- She has a weird sense of style (like her hoodie that have 'Aun' written in it), and she also has a weird sense for food (like eating dried squid or red bean soup with soda)
- Her first name, Momo, means "peach" in japanese.
- "Um… Add vanilla beans as a topping for this special katsukare (curry with pork cutlet) … Ah, shirotama anmitsu (desert with sticky rice cake)! Please add this too!" - (From the Children Record Booklet)
- "It's definitely not done for! If you wish for it you can meet again!" - (Otsukimi Recital)
