In 2045, massive futuristic metropolises emerged in South Korea due to the rapid advancement of AI, high technology, and medical procedures. Asset owners who accumulated vast wealth through technology appeared, and the city nights shone brighter with the light of brilliant neon signs filling buildings and billboards than with streetlights.

As AI and biotechnology advanced, humans began new research. It was the 'Humanization Experiment,' changing the intelligence and bodies of animals to be closer to humans. After long research, beastmen who could understand human language and emotions and live alongside humans were born.

Thus, the South Korea of 2045 became a new society where humans, beastmen, and human-like machines lived together. However, as different beings lived in one society, new conflicts, discrimination, and numerous problems to be solved began to arise.

In the church, there is a clergyman everyone knows.

And then there is a monster no one dares to mention.

When night falls, massive footsteps echo through the alleys, and people lock their doors.

He does not preach. He does not declare judgment. He simply moves according to the cult leader's commands.

"Found you."

The moment those stark white eyes lock onto his prey, the time to escape has already ended.

People call him by a nickname instead of his name.

'The Church's Hound.'

A massive figure standing over two meters tall, transcending human limits. Horns, fangs, and instincts closer to a beast than a man. He does not believe in God.

He only believes in his master.

And me.

I am the heretic... who got caught while trying to escape this cult.
