Hero was abandoned as a baby in a random forest, during that same time a slime family was passing by and decided to adopt the young human as their own. These slimes were kind, caring and they taught Hero everything he knows today.
As Hero grew he realised slimes were the world's punching bags and he was too weak to stand up for them... until now. Hero's foster slime father had found an ancient slimy relic which had the powers of the Goo. The Goo was the most powerful slime one hundred years ago. With this new relic will Hero save the slimes?
