Megumi Kato is the classmate of Tomoya Aki, who is hardly noticed by others. In the anime, she went in the same class as Tomoya since their first year, but he never noticed her. While in the light novel, during the first year, Megumi went to class E while Tomoya went to class A. After Tomoya had met her during the fate summons, she inspired him to make a dating sim game, featuring her as his Main Heroine. However, he is disappointed by her real personality. She is one of the main characters of the Saenai Heroine no Sodatekata series and is essentially the inspiration for the series title. Megumi is a cute girl with straight shoulder-length chestnut-brown hair that is usually worn down but it is long enough to be tied up into a ponytail, dark brown eyes and she is described to have "perfect proportions". Megumi is usually seen with her school uniform, or else, casual clothes, which Tomoya describes as just "normal". According to Tomoya Aki, Megumi is the most beautiful girl he has ever met. She occasionally wears a variation of the summer dress she wore when Tomoya first met her, which was designed by Eriri Spencer Sawamura to provide a better picture of how her character should look. The white beret that she wore was given to a relative, much to Tomoya's disappointment, but she is later seen wearing the same one, possibly meaning that she recovered it. Megumi grows her hair out starting the day she and Tomoya "met" after the incident at Detective Hill. After six months, she has her hair tied in a ponytail, but Tomoya notices that it has grown significantly longer. A year later, she has her hair grown out to roughly the length of Utaha Kasumigaoka's and keeps it in a similar style. However, she later cuts it back to its original length, telling Tomoya that it had awoken a "vengeful spirit" inside of her, referencing her recent conflict with him, but Tomoya believes she cut her hair again to help motivate him. Unlike Eriri Spencer Sawamura and Utaha Kasumigaoka, Megumi is portrayed as an ordinary girl with no distinctive character and she is extremely normal where she is so plain that Tomoya Aki failed to realize that he was actually classmates with her. She is described as stealthy due to her lack of presence, and the others often forget that she is even in the same room. However, Megumi is a kind and soft-spoken girl that wants the best for others and she constantly goes out of her way for Tomoya and the others to help in any way that she can. She knows little about otaku culture but never keeps Tomoya at arm's length and gives into his approaches from the start. She has strong ideas regarding friendship and feels easily slighted when they are violated. Her attitude towards Tomoya is often described as furatto and he is often the unfortunate target of snide, deadpan retorts from her. Despite this, her close relationship with Tomoya and the others brings out more of her than he first believes she is capable of showing. Her emotionless expressions often cause Eriri trouble illustrating her, so Eriri takes every opportunity to catch different sides of her personality for the game's art. Later in the series her emotions becomes more visible, especially when it comes to matters involving members of Blessing Software and Tomoya. When she was appointed leader of Blessing Software after Eriri and Utaha left, it was noted by Iori that she has a passive-aggressive personality.
