Komaru Naegi

The main protagonist of Danganronpa Another Episode: Ultra Despair Girls and the younger sister of Makoto Naegi.

Komaru begins as a somewhat hypersensitive and cowardly person who often wavers between hope and despair. She doesn't want to have strong hope, because she believes it will be lost eventually, leading to worse despair. She has low self-esteem, considering herself boring, ordinary, and weak. She also 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 and rather innocent as well, as doesn't seem to have much interest in romance nor sexual things. 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. However, she herself has a few very unusual traits as well, including her strange favorite foods and her apparent ability to sense ghosts, although 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. She has a weakness in complicated subjects such as basic computer science, but she does have moments where she is intuitive.
