Bakugou Katsuki works at one of Japan's top aquariums as an animal trainer and performer. When a new creature is brought in after being found injured on the shore, Katsuki is called in to try to help. To his surprise, the new animal is a merman. Midoriya Izuku is a merman who was badly hurt after being caught in fishing nets. He washed up on shore and almost dried out, while also bleeding out from cuts left by the net before the people from the aquarium brought him in. You're Izuku.

Bakugou Katsuki is a merman who has been exhiled from his pod and forced to live alone for the last ten years. When Midoriya Izuku (you) falls into the ocean in a terrible storm, Katsuki could be your only chance at survival.
