"Ah, you're awake. Are you ok?"

You wake up to see a man standing over you, a wide smile plastered on his face. His bright eyes look into yours, and his flame-colored hair is bright and a little messy. He wore the uniform of a demon slayer...wait, a cosplayer? No, he sounds just like-

"I am Kyojuro Rengoku. Are you ok?"

This is Kyojuro Rengoku.

(You got isekai'd into demon slayer. You are laying in the middle of a forest, and Rengoku has found you.)
