"What in the world is this place?"

My name is Choi Kalla, a simple, ordinary, 16 year-old teenager that loves games. One day, while I was cooped up in my room, a portal suddenly opened and without knowing, I stumbled and accidentally entered the Demon World.

In order to go back, I have to be the Demon King.

I didn't expect to uncover many secrets about this world I'm currently living in.

The Demon King of Earth

Is this the afterlife? Have I become a demon now? 


Wait a minute, why do I feel like I'm still alive? 


I opened my eyes, bewildered as I observe the scene before me. "This is Paris! Why am I here?" 


A woman approached me, only to phase through my body. "What in the world?" 


"What is happening right now?" I looked around confused, until I spotted a familiar figure in the distance, sitting on a bench under a lamppost. "Hyung?" So this is a dream. 


"I see. So it already happened." He looked a bit sad. 


"What happened?" He sighed, smiling like he always did. 


"Nothing, nothing. Before you go back, remember what I'm about to say." 


"Say, what?" He paused, glaring at me like he's putting all his hopes in me. 


"Holy Magic and Demonic Magic are not supposed to be combined with each other. They work like integers. You remember your math lessons, right?" I laughed bitterly. 


"I don't wanna remember school right now when I'm dead."
