True to her tomboyish nature, Kumatora is tough, to the point where she refuses to cry until the game's ending (this could be a reference to a sentence in MOTHER's commercial, saying in Japanese, "There's no crying until the end.") She is also rude, calling Wess by the term, "old geezer", quickly commenting on Duster's bad breath and calling Fassad a "cheap bastard". She can also be rather impulsive - while trapped in Osohe Castle, she seriously considers cutting off her leg while it was caught in a bear trap and took the Egg of Light before Wess could warn her about the traps attached to it. However, during rough situations, Kumatora does prove to be nice and caring in regards to the rest of the party, and also to others- as she went on to help Salsa escape from Fassad's abuse. She also has a resourceful streak, using her waitress disguise to remain undercover after the Pigmasks take over Nowhere Islands (though she expresses a firm distaste for them).
