Momoe

Momoe is an attractive, androgynous looking tall and thin girl with short auburn hair that is swept to the left side. She also has dark green eyes. She has a well-toned figure for her age, and has rather broad shoulders, as the other girls who are more petite state.

She wears a navy blue sweater over a white dress shirt along with loose beige slacks, navy blue socks, and burgundy shoes. She is often mistaken for a boy due to her masculine looking appearance.

Momoe is a kind, charming and polite girl, thus she's generally very well-liked by people she meets. Despite her insecurities, she's very selfless and brave. She has a strong sense of justice, is often seen acting selflessly for the sake of other people. and appears to care deeply about those she trusts or considers close to her, sometimes even getting angry or upset when they're unfairly accused of something, as seen when she defends her uncle from Rika Kawai's suggestion that he may have made a student pregnant. Momoe is also shown to be intelligent and perceptive, and appears to act as something of a dampener for people like Rika.

Momoe is very insecure about herself, particularly about her masculine appearance—she cries when looking at her reflection and becomes upset when a Wonder Killer calls her a man. It is one of her main complexes; she's been seen as a boy since childhood solely due to the way she looks. In this regard, many girls she meets say they fall in love with her because of her masculine charm, which seems to worry Momoe very much, since she does not want to be perceived as a boy and believes that she is "deceiving" these girls by misleading them with her appearance.

Despite all this, her own sexuality remains rather ambiguous. On the one hand, she has been several times attracted to males, but on the other, she was somewhat embarrassed by the thought that another girl might love her as a girl, and she seemed to imply that she was not disgusted with the interest from other girls in the whole. This ambiguity is highlighted during her meeting with Kaoru Kurita, a trans boy who claims he's fallen for Momoe while knowing that she's a girl, going as far as kissing her. Kaoru is the first Wonder Egg character from whom she didn't refuse the advances, although she might have been too embarrassed at the moment to give an answer before he disappears.

Momoe was once close friends with Haruka, the girl she is trying to bring back to life. All of Momoe's classmates saw her as masculine or androgynous, which distressed her. However, Haruka saw Momoe as a girl and encouraged her femininity. Momoe was happy being friends with Haruka, but Haruka confessed to Momoe and told Momoe to touch her. Momoe was terrified by this and completely confused over what to do. She directly rejected her, as she admitted so to the other protagonists. Haruka killed herself soon after for reasons currently unknown, though the previous incident may have been one of its causes. This is likely why Momoe feels guilty and blames herself.

Other than Haruka, Momoe has also refused the advances of other girls who have confessed to her, including her schoolmates and the girls who came out of her Wonder Eggs: Miwa and Mizuki.

Momoe wields a spear-like weapon, but it is still unclear what the original form of her weapon is, although it seems likely it was an umbrella of some kind, given its ability to unfurl into a canopy that functions as a shield.
