Deku: The Sekiryuutei of Hope

Men. They don't have Quirks, don't have much talent in today's age, and they're quickly diminishing in numbers. One teen, Midoriya Izuku, is gifted a power unlike any other. He carries a heavy burden, to defeat the Will of Evil as the Will of Good. Will Izuku, the world's only Quirked man, survive in this harsh world, or will he give in? [Extremely massive harem.]
