The Heroine is My Stepsister, and I'm her Final Boss - Chapter 1: Despair and Death.

Can't a man maintain his dignity while preparing for the end of the world? Is that too much to ask?

The Tower was all I knew... all any of us knew, and just like that, it was gone. Monsters the likes of which I'd never seen ravaged the land of my ancestors. They burst through the outer walls and stormed the city. No one could have been ready for that. But now... Now I have a second chance.

After the collapse of the known world, I woke up to find myself on the First Floor of the Tower. I was young and healthy, 18 again, and sitting in the same classroom that marked the worst days of my life. Confused and excited, I accepted this gift, deciding to use my vast knowledge of the future to climb the Tower in preparation for the end of the world.

Maybe I'll help some folks along the way? Who knows. Survival comes first.

The clock is ticking, and I'm left with only a century to build a Deck powerful enough to survive the end. Things to do... What's first? I need Essence, and I need power. I'll have to climb the Tower to acquire both of these. Some of the zealots will try to stop me, need to look out for those. What if-

“Hey, kid! Hand over the pouch or-”

Stab

Sorry, where was I? Ah... there's a spot of blood on my suit. What a lousy morning.

In this world of blood and fantasy, century-old Rowan Wilder has to not only survive, but thrive as he powers his way to the top of the Tower. The Demonic Plague that has twisted the creatures on the upper Floors is the least of his worries. Cane in hand and Summons by his side, he'll have to tear his way through the monsters, as well as the humans who want to stop his ascent. Of course, he can maintain a sense of decorum while he faces these trials, right?

The King Of Assassins was a monster that reigned over the world of hitmen for long years. He was the absolute peak that no other being could reach. His name reached the ears of every powerhouse in the world and sent shivers through every human.

Yet, his legend came to an end suddenly when he died in unknown circumstances.

However, instead of disappearing forever, he was given another chance in another world by the goddess of reincarnation. It was the world of an old book that he read back in the time. A world where everything was possible, where humans could reach new heights that were impossible in his old life.

But, this place didn't seem to be normal as it carried a huge surprise that will make his journey seem all the more interesting.

The Goddess of reincarnation wasn't as holy as anyone would think. She was nothing but a twisted being who found a toy to play with. The goddess manipulated the world that he was going to and changed all the heroines into these twisted beings that fit her character. They were all now harboring this unhealthy obsession toward him and trying with all their powers to take him away for themselves.

Trample over the proud, suppress myriad paths!To vie for the ultimate way, only I, the Sword Sovereign, shall stand supreme!My sword may seem ordinary at first glance, but rest assured, it will be your end!

There is a hated person on the popular anime,「Girl & Shuya」.

The Denning, House of the Duke’s third son, or also known as the Piggy Duke, Slow Denning.

As a person hated throughout the school, he had a lot of reason to be hated, things like he looks down on people, he brags about his pedigree, fat, real orc, and the Piggy has a tragic future waiting for him, he would be banned from his country at the end. And he even has the misfortune on the side that the retainer that he secretly gives his heart to, was stolen away from him.

Wondering why I’m talking about this?

It’s because I reincarnated to that Piggy Duke!

I will definitely make the Piggy Duke who had the number one position on the anime’s popular poll, also the number one in the real world!
