When Duke dies in a perfectly ordinary accident, he expects… well, nothing. Maybe darkness. Maybe peace.
What he doesn’t expect is to wake up in the middle of a cosmic bottleneck collapse.

The Nirvana Realm, the place where souls are cleaned, sorted, and recycled into new lives is under attack by beasts from another universe. Space tears open, memories scatter like broken glass, and thousands of souls slip through the cracks before the ancient system can erase them.

Duke is one of them.

Instead of reincarnating as a baby or starting life fresh, he’s sucked into a Dungeon Tower during a creation cycle and reborn as the weakest thing imaginable:

Floor Boss, Floor 1, Rank F.
Species: Beastman Hybrid (Larval Stage).
Talent: Fusion.

He’s not special. He’s just unlucky enough to be caught in the mess.

But the Dungeon Tower is a cruel place.

Higher floors extort lower floors through essence taxes. Climbers form factions, guilds, and empires inside the tower. Some floors are ruled by monsters, others by humans. Some floors are battlefields. Others? Black markets, forbidden realms, or criminal safe zones.

And Duke… Duke accidentally kills a climber who turns out to be someone he shouldn't mess with. Now a SSS-rank guild with a temper problem and a tendency to wage genocide when angry is ready to rain him hell. 

If that wasn’t bad enough, Duke discovers his Fusion talent can turn corpses, human or monster into evolution materials.
Which means every climber who comes to kill him… is also a stepping stone.

This is the story of a monster trying to survive in a world where even monsters have politics, rent, taxes, and way too many problems.

Sometimes tragic.
Sometimes hilarious.
Always brutal.

And if Duke plays his cards right, he may just evolve into something the Tower wasn’t prepared for.
