Mafuyu is a smart, humble, and kind girl who people can rely on due to her sincerity and consideration of situations. Unknown to other people other than members of the unit and herself, though, Mafuyu lacks empathy and passion, thus having difficulty on getting an emotion. Speaking in a few words, often to the point of cruelty, she often says she doesn't know when asked about opinions. When she feels emotions, Mafuyu tends to chase those in order to understand them.
