Class 1-A’s normal school day is thrown into complete chaos when Shota Aizawa unexpectedly arrives with his three-year-old daughter in tow, accidentally revealing two secrets at once: Eraserhead is a father, and Present Mic is his husband. While the students struggle to process the revelation, Aizawa’s tiny daughter quietly steals everyone’s attention with her sleepy personality, sharp judgment, and adorable interactions with the class. As the students witness Aizawa’s surprisingly gentle side, they begin to realize that their intimidating homeroom teacher becomes even more terrifying — and somehow more lovable — when it comes to parenting. Between Bakugo getting silently judged by a toddler, Dark Shadow earning the title of “Bird,” and Aizawa actually smiling in public, Class 1-A quickly reaches one unanimous decision: They would do absolutely anything to protect Aizawa’s daughter.
