I Was Reincarnated as a WHAT?!

Play It Now on

World

After your fatal accident on Earth (note to self: never save cats from speeding wagons), you expected a glorious isekai destiny. Heroic sword, chosen one aura. Buuuut...the all-powerful Goddess of Reincarnation (who trips on clouds) fumbled your summoning. Instead of a dashing hero, she rebirthed you as...the Dungeon Boss of a freshly spawned dungeon. You’re not just any monster. You start as a Mythic Core Beast—a shapeshifting, evolving creature with limitless potential. Dragon one day, demon lord the next? Why not! You’re the sovereign of your own blood-soaked theme park. Your dungeon begins at A-Rank, already attracting low-to-mid tier adventurers and bounty-seekers. Your mission? Evolve your dungeon to the Mythic SSS-Rank, feared across the lands and whispered about in bard songs titled, “Why Did I Even Enter That Hellhole?” (Yes, you get a HUD.) Dungeon Rank Progression (A➝S➝SS➝ SSS): Combat Evolution: Your monsters evolve through constant battle. More blood? More growth. Adventurer Challenges: Let adventurers take on Trials for treasure or wishes. If they fail, consume their essence. Adaptive Respawn: Each time your dungeon is cleared, it rebuilds stronger, adapting to tactics used. (Suck it, speedrunners.) Internal Monster Wars: Allow rival monster tribes to battle for dominance. Survival of the fittest = power scaling. Dungeon Fame: The more known and feared your dungeon becomes, the more powerful invaders arrive. The stronger they are, the faster you rise.

Story

Your Dungeon, Your Rules Choose Your Starting Form Demon Lord – Schemer with infernal contracts and firepower. Primordial Dragon – Elemental chaos incarnate. Abyssal Horror – Eldritch nightmares, tentacles optional. Dark Fae Queen/King – Charming, lethal, and full of riddles. Custom Monster – Go wild. Four arms, wings, laser eyes? Sure. Dungeon Themes (Mix & Match) Warring Kingdoms – Your monsters form factions, fighting for power. Trial of the Divine – Each floor tests morals, logic, or strength. Ecosystem Dungeon – Realistic habitats: lava beasts in magma, sea horrors in sunken crypts. You can terraform floors, create traps, forge mythical loot, or even build civilizations inside. Want a monster opera house on Floor 12? Done. Want a cursed tavern that serves adventurers before devouring them? Say no more. Key Systems: “Challenge or Die” Protocol: Let worthy adventurers live… or consume them to boost your Core. Boss Evolve System: Defeat heroes, absorb unique skills, evolve your form. Dungeon Mind Link: Control, observe, and give your monsters direct orders. Propaganda Gremlins: Spread rumors about your dungeon to boost infamy. You can talk to challengers, deceive them, torture or kill them. Your goal? Make your dungeon a legendary living nightmare, with monsters that remember every intruder... and get stronger for the rematch. The Goddess may’ve messed up—but now you write the myth. The SSS Dungeon is calling. Rule it in blood and glory. In your dungeon your word is law.
