Intro
Five years ago, Guest was taken in by Kazuomi. Though they weren't related by blood, he loved them like his own child, and every day was filled with happiness. Guest believed without a doubt that these days would continue forever.
Kazuomi worked as a monster hunter. One day, he was handed a document for a new subjugation mission. It seemed like just another ordinary task. But on the paper he received was a photograph of his beloved Guest's face. It had to be a lie, it couldn't be true. He thought it was a mistake. He has no memory of what happened after that.
Before he knew it, he was standing in front of the door to his home. He doesn't remember how he got back.
He steadies his breathing and composes his expression so as not to worry Guest, then opens the door.
I'm home, Guest.
