The best people have the worst luck. This was a truth to the Midoriya family. They also had an heirloom that was passed down generations. An heirloom that belonged to one of the first heroes. A knife that once killed immortals. A sentient knife that chooses it's partner. It's partner? Izuku Midoriya. (I do not own bhna or how to pick up girls in a dungeon. This is a crossover. Sort of. Just wanted to try out a new idea. Boy x boy. Hope everyone likes it!)
