MHA: Puppet Heroes

Once every night, the Moon Bear King steals away a soul of a child, he has done this many times over, but recently, he had did something different. He mostly went for unknowing boys, but recently he went for girls, did he discriminate against gender? Apparently not and he made certain that he wasn't sexist. Of course almost all girls would be forced to clean Castle Grizzlestein as the boys were made into cooks and the girls were made into maids, but it wasn't because the Moon Bear King saw most of them as ugly, as he had to put up with Ezma Potts, but it was really because he actually needed cleaners, and the grubs can only do so much.

But one day he kidnapped not one, not two, but three children, two boys and a girl. The boy and girl just so happen to be brother and sister, but not just any brother and sister.

They were Izuku and Izumi Midoriya. Their mother were wary of them sleeping, as a total of 592 children around the world could never wake up, leaving hospitals around the world bursting at the seams with children that had seemingly went into a coma. But now Izuku and Izumi would learn why that was so. And they were both five and four years old respectively. With his sister doomed to be the future wife of the Moon Bear King when she got older, as well as being doomed to never be able to see their mother ever again, Izuku must team with another young boy named Kutaro to save the children and rescue his sister and get home.

Can Izuku and Kutaro along with Izumi defeat the Moon Bear King, or are they doomed to be puppets for the rest of their lives?
