Unlike Chito, Yuuri is illiterate. She can't read and has trouble with spelling when she tries to write, often prone to misspelling words.
In contrast with Chito's survival-oriented temperament, Yuuri displays a more laid-back, almost carefree attitude. Though possessing a generally poor memory, Yuuri is able to recall facts with relative ease when related to food.
Yuuri is knowledgeable regarding firearms and she is a competent marksman. She was able to teach Nuko different calibers of bullets. She carries an Arisaka Type 38 rifle with her.
Near the end of the manga, it is revealed that she is somewhat afraid of darkness, and relies on Chito to help overcome it.
