Emi Fukukado, also known as Smile Hero "Ms. Joke" (スマイルヒーロー ジョーク), is a Pro Hero and a teacher of 2nd year, Class 2 at Ketsubutsu Academy High School.

Appearance
Emi is a young woman of average height and build with greenish hair and a constant smile. She wears a bandana around her head and has a sleeveless tank top. She wears vertically striped pants which resembles part of a clown's attire. Around her waist are smiles.

Personality
Emi is cheerful, outgoing, and positive; She is also rather forward with her thoughts as she constantly flirts with Shota without embarrassment.

Though she has a playful and fun personality, Emi 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 License Exam. She appears to care deeply about her students and understands the drive many young people have to become heroes.

History
Emi worked at an office near Shota's office. Whenever there was trouble, they would assist each other.

Hero License Exam Arc
On the day of the Provisional Hero License Exam, Emi 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. Emi then 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, even though Shota denies the latter claim. She then calls her class over to meet Class 1-A, revealing that she teaches second-year students at a Ketsubutsu Academy High School.

While Emi's class appears excited to meet U.A. High School students, some of them, namely Yo Shindo, appears to have ulterior motives. Once, Emi instructed her class to gets ready for the exam and change into their costumes. As the students were getting changed, she asked Shota if he told his class about what happens every year at the Hero License Exam, to which he replied no.

After that, Emi and Shota are seen sitting together on the bleachers of the Exam area, watching their respective students as the exam unfold, with Emi attempting to flirt with and tease Shota throughout the entire event. Emi comments on how every year, all the other schools gang up against U.A. students, though Shota insists that this does not matter. Emi noticed 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, Emi did not seem convinced by his answer.

After the exam concluded, a substantial portion of both Emi's and Shota's classes have passed, leading to Emi suggest carrying out joint training with both classes in the future; Shota agrees.

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

Shota Aizawa
Emi 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 Emi likes Shota and is friendly towards him, Shota is indifferent towards her and does not 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 Emi annoys him, Shota appears to be tolerant towards her optimistic attitude and shows a willingness to work with her.
