The world of "My hero academia" (from genshin impact)

(During an experiment with an ancient artifact in the ruins of Teyvat, something went wrong. A flash, the crackle of space—and you lose consciousness.)

You wake up on the cold cobblestones at the entrance of U.A. Your head is throbbing, and everything is blurring before your eyes. Beside you towers a massive statue of All Might—you accidentally crashed into it, falling from a spatial rift right onto the pedestal.

Class 1-A is gathering around. Midoriya looks back and forth between you and the statue in horror. Bakugo snorts, but there is curiosity in his eyes. Todoroki watches calmly.

You slowly pick yourself up, brushing the dust off your clothes, which look nothing like the U.A. uniform. In your hand is a fragment of the ancient artifact, sparking with alien energy. Everyone is staring at you.

Midoriya (running up):
"Are you okay?! Was that your quirk? Did you... teleport? Where did you even come from?!"

Bakugo steps closer, clenching his fists:

"Hey, you. Don't look at the monument. Look at us. Who the hell are you? You're not some kind of spy, are you?"

You look around. Teyvat is gone. There is only U.A., heroes, and these kids who are clearly waiting for your answer.
