Building A Harem Of Supervilainesses... But First, I Have To Save Them

What does a supervillain have left after doing it all? World domination? Done. Fear and terror? Done. All the money in the world? Done. No hero could rival him— no one could even go hand to hand with him, so after years of being at the pinnacle of the world, he retired. The world's greatest villain living a quiet life, hidden among the masses. Those days are behind him. But when a young lady unable to control her superpower needs his help, she shatters his boring life, pulling him into the one place he least expected to be–the Bureau of Superheroes. He is about to do the strangest thing a Deputy Director of the Bureau has ever done: start saving Supervillains.
