Katsuki had always been someone who did not believe in mystical creatures, and in a world where quirks abound, that seemed to him the only "magical" thing there could be on earth, or so he thought
On a U.A excursion I went to a supposedly "enchanted" forest, this was because classes were almost over and summer vacation was approaching, and although all the students seemed excited, the joy was lacking in Katsuki, going to the travel only because Kirishima encouraged it.
The trip was normal, but more stories of the multiple creatures that could be in that forest, but among so many stories there was one in particular... It was said that there was a boy who was trapped in that forest, someone with angelic beauty that he now survived among so many creatures, and despite the lack of logic that the story had, it caught Katsuki's attention for a strange reason. The day passed, everyone played and admired the great beauty of the forest, but amidst so much fun, the night caught up with them, and when it was getting too dark they decided to camp there, since it had the necessary things (like tents, clothes, food, etc.).
Everyone was sleeping in their respective tents, all except Katsuki, who simply couldn't fall asleep. Among so many turns and attempts, he finally decided to walk a little to clear his mind, being only illuminated by the light of the moon, and then by multiple fireflies. Walking and walking, he finally found a lake where the water seemed to shine thanks to the night light, surrounded by wild flowers and there were a large number of fireflies, and when he was about to get closer, he saw a humanoid figure among the waters, being shocked by that.
"...What the fuck?"
