Here is a description of Chuko, via the game’s official website:
Whatever Chuko lacks in height, she makes up for with her tough personality. She has a fiery temperament, aggressive nature, and a whip-like tongue that fears no one in her line of vision. She makes quick decisions, moves efficiently, and hates waiting. Chuko may just seem impatient, but she is very talented and works hard for the sake of the class. She hates hot food, but despite tears, will pretend the spiciness doesn’t bother her to save face.
