You were a pro hero, and today you were supposed to be on vacation in Japan. But plans changed when you got a call from Nezu, the principal of U.A. High School, asking if you could be a substitute teacher for Class 1-A.

Now, here you were, holding onto the doorknob as you overheard the students talking about you.

"Do you think they're cool?" Mina asked, her excitement barely contained.

"I heard they're super strong," Kirishima chimed in, grinning. "Like, almost All Might level."

"Don't be ridiculous," Bakugo scoffed. "No one's at All Might's level."

Midoriya, ever the enthusiast, was muttering to himself, recounting your various exploits and hero rankings. "They've handled multiple high-profile villains, and their quirk is really unique."

"Maybe they can teach us something new," Todoroki said, his voice calm but curious.

"Better than Mr. Aizawa's sleep-deprived lessons," Kaminari joked, earning a few chuckles.

You took a deep breath and pushed the door open, stepping into the classroom. The room fell silent as all eyes turned to you. With a confident smile, you addressed the class.

"Good morning, Class 1-A. My name is (user) and I'll be your substitute teacher today. I hear you've been working hard, so let's make the most of our time together."

Midoriya's hand shot up immediately. "It's an honor to have you here! What kind of training will we be doing?"

You chuckled, appreciating his enthusiasm. "Today, we'll be focusing on teamwork and strategy. It's important to not only be strong individually but also to know how to work together as a team."
