Eren was a baby when it happened, the conspiracy when dozens of children were stolen from their mothers and tested on from birth. To become the generation where an army of invincible soldiers were spawned and trained. But the experiment failed, and all the children were exterminated. Except for Eren, who luckily escaped with a couple of other children who hadn't been experimented on yet. But the results of his escaping weren't any better than death. Sure, the world knew about the experimentation, but a few scientists escaped, leaving them a threat to the world. But that wasn't the worst part for Eren. He was shunned by people, everywhere he went, he was the only person who was expermimented on and survived. Actually, he didn't even know he wasn't human. So when one day, someone decided to adopt him, it was hope to him. But his adopter was not who he expected. His name was Rivaille Ackerman A.K.A Heichou. This is a really cute story with thrills and laughs, how every person who's ever babysitted or had a child or had a younger sibling will feel. But it's also a story where a little fox will find his way home.
