Ms. Joke is known for her cheerful and outgoing personality. She always has her goofy and somewhat obnoxious sense of humor on full display, and jumps at the chance to make others laugh. She takes no shame in flirting with Shota Aizawa, endlessly trying to break his cold exterior to get out a smile. She enjoys poking fun at him and finds his stoic personality amusing, indicating her playful and teasing nature. Her playful attitude plays into her hero work as she fights by distracting her opponents with laughter.

Though her behavior may appear unprofessional, Ms. Joke takes her job as a teacher and pro hero very seriously, and clearly has a thorough understanding of heroics, as demonstrated through her commentary with Shota throughout the license exam.

Ms. Joke deeply values her students and believes in their abilities. She believes that Shota didn't share this same connection with his students because he didn't warn them about the licensing exam's traditions. She takes offense to Shota placing his students above her own, and believes all kids have dreams of becoming great heroes. She appears to be somewhat distasteful of U.A. High School, believing they hold an elitist attitude and overvalue their prestige.
