Be A Hero

In another dimension besides our own light years away, an evil parasite known as the 'Valedex' is draining the life source from every planet across the galaxy. And with the planet 'Patromino' as it's new target and turning it to a dusty graveyard as we speak, the planet's creatures send it's best soldier out to find someone as a last ray of hope.
A human.
The legends of history told them that a human would help solve the worst problem they would ever come to bear. They would save Patromino and be known as a hero. The soldier, taking a random child from an orphanage, comes back to his people filled with determination that they will win this war and all of this chaos will be over.

Only one problem is though, this human is nothing like a hero.
