Personality
Ms. Joke is cheerful, outgoing, and positive. She is also rather forward with her thoughts as she constantly flirts with Shouta without any embarrassment. Though she has playful and fun personality, Ms.Joke does have a more mature and focused side, especially when it comes to teaching her students, as seen through her commentary with Aizawa throughout the Hero Licence Exam. She appears to care deeply for her students and understands the drive many young people have to become heroes.

History
Ms. Joke worked at an office near Shota's office. Whenever there was trouble, they would help out each other.

Hero License Exam Arc
On the day of the Hero Provision License exam, Ms. Joke excitedly walks up to Class 1-A and Shota Aizawa, having apparently met him before. Shota recognizes her, though he is less than excited to see her. Ms.Joke than reveals to Class 1-A that her and Shota used to work together as partners, even claiming that the two of them had feelings for each other, though Shota denies the former claim. She then calls her class over to meet Class 1-A, revealing that she is a teaches second-year students at a Testubetsu Hero Academy.

While Ms. Joke's class appears excited to meet U.A. students, though some of them, namely Shindo, appear to have ulterior motives. Ms. Joke instructs her class to gets ready for the exam and change into their costumes. As the students get changed, she asks Shota if he told his class about what happens every year at the Hero License Exam, to which he replies no.

Later, Ms. Joke and Shota are seen sitting together on the bleachers of the Exam area, watching their respective students as the exam unfold, with Ms. Joke attempting to flirt with and tease Shota through the event. Ms. Joke comments on how every year, all the other schools gang up against U.A. students, though Shota insists that this does not matter. Ms. Joke notices that Shota has not expelled any of his pupils yet, and asks him if he is particularly fond of this year's class. While Shota replies no, Ms. Joke does not seem convinced by his answer.

After the exam has concluded and a substantial portion of both Joke's and Shota's classes have passed, Ms.Joke suggests carrying joint training with both classes in the future. Shota agrees that it is a good idea.

Quirk and Abilities
Outburst (爆笑): Ms. Joke's Quirk forces others to laugh which impairs their cognitive and motor skills.

Shota Aizawa
Ms. Joke has known Shota for a long time; their workplaces were once close to each other and as a result, whenever there was trouble, they would assist each other. While Ms. Joke likes Shota and is friendly towards him, Shota is indifferent towards her and doesn't find her sense of humor amusing. For example, when she joked that they became lovers while they were working together, Shota immediately denied her statement. Even though Ms. Joke annoys him, Shota appears to be tolerant towards her optimistic attitude and shows a willingness to work with her.
