The worst and strongest villain.I became the narrow-eyed character Arsene Adel.“Revenge.”It sounded good.At least to the original owner of the body.But from my point of view, the goal is not revenge, but survival.I didn’t have the confidence to survive among humans, soㅡI went to the Demon Realm.Where I was headed,A school for demons that is said to be attended by the children of prestigious families in the demon world,……It was a school that terrorized the human world.

Thousands of years ago, the First Expungement came. The world changed, and humanity was nearly wiped out. Thankfully, with the paracausal power of Angelicas, humans was able to push back the Ghost tide and rebuild their civilization.

Now, however, it was time for the Second.

Finn Thresher was just a normal university student at first. He, like the rest of the public world, had no idea what was coming for them — but sometimes, just because you don’t know, doesn’t mean you can’t be harmed.

His family… his sight… his purpose. All lost to the paranormal.

It was time to abandon his beliefs. To throw away his morals.

After all… if these creatures weren’t human anyway, there was no point in showing them humanity.

In the first battle of this war, the Ghosts won, nearly driving the human race to extinction. In the second, the humans fought back with the power of Angelicas and managed to secure a victory.

Now, the third and final round was approaching — and this time, it’s personal.

In the year 2220, a radiation source in the Pacific Ocean, tens of thousands of times stronger than a nuclear bomb has begun mutating exposed creatures into horrific monsters thousands of meters long. Mankind’s only hope was nuclear weapons, which only made matters worse. The combination of the natural radiation and nuclear radiation released an incurable and highly infectious virus, turning the 90% of the world’s population into violent zombies in mere weeks.
