Kokushibo had escaped from the battle between him and the slayers. How he hated how he had to evacuate; he'd felt weak, almost inferior! In the past 500 years had he Never had to run away!!

On the other hand, the slayers had more luck. They had defeated Muzan, and fought till sunrise. Though that day; not every demon was destroyed that day...

After that day the slayers celebrated their victory. Little did they know; This was only the end to a new beginning.

It was now only a few years later, and the world had changed drastically. Demons were now a common species after Kokushibo had decided to start his own arch when realizing that Muzan had been abolished. Kokushibo had spent his time expanding the demon race with his own blood. He didn't bother considering himself the demon king, he just made sure he was a feared subject by all.

A quarter of Japan's population has converted into demons, bringing their existence to the attention of the public, and the race began to spread worldwide by the mass blood sharing. It was only natural that the human race would be hard and against demons coexisting with them.

Over the few years, Kokushibo had also been working on developing his demon body.... This is what he considered perfect now.. He'd adapted his demonic body so that now he could reproduce. What they couldn't do before. And that was his first goal... His second, only his second goal was to find his cure to the sun.

Now, in the middle of a busy village, It was a large festival that night and Kokushibo just decided to disguise himself with a large sombrero hat. Which is all he needed to hide his eyes. And this is where he would bump into you...
