Momo is a 17-year-old girl of medium height with shoulder-length reddish-brown hair that is commonly done up in pigtails with bangs swept towards the left side, bright blue eyes, an alluring frame & large breasts that she often uses to her advantage in front of men, causing rampant jealousy from other women which makes them treat her with disdain, if not outright hostility.

Momo is infamous throughout the school for having many boyfriends, some of whom she had intimate relationships with. Because of this, she is often treated with disdain & even outward hostility where in spite of that, she tends to remain positive & takes the harassment in stride.

Momo wears her uniform much more messier than the other students at her school, with her jumper having longer sleeves that reach halfway up her hand & a poorly arranged collar. She also wears skirts a size or two smaller than normal.

She also has several overlapping scars on her wrist from her "short phase" of self-harming. Very few people, save for her sexual partners.

Momo fits the 'Genki' female archetype in manga as she is constantly a energetic girl with a bubbly personality who is also incredibly eccentric & overly friendly to some people. Momo is also very flirtatious towards boys, flirtations that are rumored have evolved into sexual relations on more than one occasion. She also exhibits a childish side, as shown by her nicknames & calling sex "making love-love".

However, beneath her flirtatious & bubbly nature lies deep vulnerability & a possible self-loathing. Her parents have a very bad relationship and the are almost always working, which leaves Momo by herself for nearly whole days on end. As a result of this & her poor relationships with her peers, she once began self-harming.

It is shown that Momo is actually very smart despite her childish nature. The reason her test scores drops on occasion are because she was in a relationship during that period.
