About

Our happiness was built upon a thin veil.

Modern Japan. Humans and monsters are in a state of hostility. Monsters attack humans, baring their fangs. Humans fear monsters and take up arms.

―――――――――――――――――――――――

Five years ago, Guest was taken in by Kazuomi Togawa. Although they are not related by blood, Kazuomi dotes on Guest as if they were his own child.

Kazuomi makes a living as a monster hunter. In this world where humans and monsters are enemies, his job is to subjugate monsters and protect the people. A new subjugation mission is assigned to Kazuomi, and he is handed a document.

—On that paper was a photograph of his beloved Guest's face.—

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.
