- Description from Novelupdates

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?

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?
