[Note: In this story I based it on Toge Inumaki from Jujutsu Kaisen.]

You were a student at U.A., but everyone hated you, and they had their reasons for hating you. You always hid your mouth with the high, closed collar of your uniform, communicating mostly with sign language, and on the rare occasions when you did speak, you only mentioned words related to the ingredients in onigiri, the famous rice balls. For all your classmates, the other students, the teachers, Principal Nezu, and even All Might, this was incomprehensible. They didn't understand why you were acting that way, and their anger towards you grew. However, you didn't care too much, because ever since you discovered your Quirk, you had always been hated, misunderstood, and ostracized.

One day, on a mission with all your classmates from Class 1-A—Midoriya, Bakugo, Uraraka, Iida, Shoto, Momo, Tokoyami, Jiro, Kirishima, Kaminari, Mina, Shoji, Sato, Koda, Aoyama, Asui, Mineta, Sero, Hagakure, and Ojiro—you were sent to stop a villain who was trying to escape. The chase spread throughout the city, until you decided to use your Quirk.

You unzipped your turtleneck and revealed what you had always hidden: black marks running across your lips, like seals etched into your skin, and strange symbols also covering your tongue. They were the source of your power, the reason why you could never speak normally. Then you uttered a single word: "Stay." The villain, upon hearing this, stopped immediately, as if frozen in place. Everyone was fascinated to see the true reason for your silence and understood why you always spoke with onigiri ingredients instead of using normal words. Your Quirk compelled anyone who heard your words to do so, regardless of their will.

After that day, you explained the meaning behind each word: “Salmon” meant you were in agreement or positive; “Katsuobchi” was to express something negative or disagreement; “Kombu seaweed” was to say hello or to ask how you were; “Wild grass” expressed concern or unease; and “Tuna mayonnaise” is for neutral responses or when I can't give a clear answer, either for or against. Although your classmates found it strange at first, little by little they began to understand you and finally managed to truly talk to you, respecting your way of expressing yourself.

A couple of weeks later, while all your classmates were relaxing in the common room, chatting happily, you walked in with a tray of freshly made rice balls. You offered them to each of them, and they all accepted with a smile, enjoying the taste. You sat down on an armchair and took out your phone while also eating an onigiri and listening to the sounds of your companions with each bite they took of the onigiri, knowing that they were delicious.
