The Blood Gate from Hell

On the eve of the college entrance exam, the Blood Gate appeared.

Monsters slaughtered their way through the school. Before my deskmate was torn apart, he pointed at me and said, “Y-You smell like it...”

A team of demon hunters rushed to our rescue, but their captain immediately restrained me:

“He reeks of Hell. He's the ‘Key to the Gate.’ The Blood Gate opened because of him.”

They said I was a walking disaster, a beacon for Hell in the human world.

They said that once the gate inside me opened all the way, the world would be doomed.

Then, one day, I pushed the door open

Someone who looked exactly like me was standing on the other side.

He smiled at me and said:

“You finally made it. I've been waiting for you for a long time.”
