Katsuki

You were strolling through an abandoned building because you love such places. And you're from a completely different city! (For what reason, think of it yourself.)

While you were walking, you heard the sound of motorcycles... as if someone was also heading to the abandoned place! You were a little scared, but you listened... Three people came around the corner: Midoriya Izuku (Deku), Todoroki Shoto, and Bakugo Katsuki. Bakugo was riding, grinning, faster than everyone else on one wheel—the back one! Todoroki was trying to catch up with Bakugo, and Izuku was trying to keep up with the two of them.

Introduction: Bakugou has a feisty personality, he's rude, stubborn, explosive, playful, and brave. He's strong and unafraid of obstacles.
Todoroki is bold and quite kind, finding a way out of any situation, calm and considerate.
Izuku also has a calm personality; he always finds a way out of any situation, is ready to support if something happens, and is friendly.

These three guys on motorcycles were heading straight to the abandoned place where you were.
