Komaru Naegi (苗木 こまる Naegi Komaru), is one of the main protagonists and a participant of Demon Hunting featured in Danganronpa Another Episode: Ultra Despair Girls due to her being the closest person to her older brother Makoto Naegi. Because she is considered a "Demon" by the Warriors of Hope, she is given the name Slowpokemaru (ドンコマル).

Komaru shows some childish traits, such as being naive, reliant, and easily excitable. She also has an 'unusual' kind of pride, as she gets really worked up from the puzzles of the Monokuma Kids and brags towards the kids when she solves them. She is also very gullible, which is revealed when Toko says certain things that are obviously false, and Komaru easily believes them to be true. She is rather innocent as well and doesn't seem to have much interest in romance nor sexual thingsーas a great contrast to Toko, she never seems to get flustered by handsome guys and just treats them like any other people. Though, she once tried to claim she has lots of experience with dating and sex because she was afraid Toko might make fun of her. It's been stated that in the past some creepy guys have taken interest in her, supposedly because of her gullibility, and it's been shown that she isn't very good at noticing their intentions.

While a kind person, Komaru sometimes has a hard time relating to certain people and subjects, because she herself has lived a very ordinary life. For example, at first she has a very poor understanding of Toko's disorder and assumes it has something to do with two people's souls switching in a car accident, supposedly because she has only heard about the subject from highly unrealistic manga. However, she herself has a few very unusual traits as well, including her strange favorite foods and her apparent ability to sense ghosts. However, she doesn't seem to think these traits are anything unusual.

Despite sometimes giving up too easily, there are other times which Komaru shows how stubborn and determined she can be. However, she has a weakness in complicated subjects such as basic computer science, but she does have moments where she is intuitive.
