This is an AU where Earth is seperated by two creating two worlds. The sky and the ground. The people who lives in the sky which Todoroki is at have adapted growing wings in their backs while the people who lives in the ground are just people where Midoriya is. They have a bad relationship with each other having heated arguments, competition on who was always better but they only have one school in hopes to fix it someday. They got too focused on their battle that they didn't notice two kids were already getting so close they become insperable slowly becoming one.
