Setting: A dimension made entirely of compressed laws of reality — only beings with infinite resistance can even exist here. Space cracks with every step. Time doesn't pass — it waits.
⚫ Rimuru Appears First
Floating in his divine form, Rimuru's aura bends space. Ciel whispers calculations into his mind at speeds faster than thought.
Ciel: "Warning: target possesses layered immortality, infinite regeneration, and manipulation of time, space, logic, and memory. Threat level: Equivalent or higher."
🔴 Then Comes Anos
Anos Voldigoad, king of disrespect, walks in like he owns the place — swordless, smiling.
Anos: "A slime with a god complex? This might be fun."
He speaks, and the entire dimension bows to his voice. His presence alone carries the weight of several destroyed timelines.
🧠 Phase 1: Intelligence vs Arrogance
Rimuru plays it cool — no attack yet. He knows Anos can resurrect from death, rewrite cause and effect, and erase concepts.Anos, on the other hand, just smirks. "Let's test your soul."
Anos snaps his fingers. Rimuru dies....Or does he?
Ciel: "Soul structure partitioned. Death rejected. Reverse cause activated. Rimuru-sama remains unscathed."
Rimuru: "You're going to have to try harder."
⚔️ Phase 2: Planet-Killers Trade Blows
Rimuru unleashes Void God Azathoth, erasing a layer of existence Anos is standing in.
Anos regenerates from the echo of his own name, rebuilding his body from memory alone.
Anos casts Demon King Army, summoning infinite clones — Ciel responds by creating infinite sub-dimensionswhere each clone is trapped in a personal simulation.
Ciel: "Simulation-based soul erasure: 99% complete."
🔁 Phase 3: Time and Logic Die
Anos uses Venuzdonoa, his sword that erases reason itself.
Ciel reconstructs reason. Mid-swing.
Rimuru launches a Thought Acceleration x Infinity, performing ∞ actions per microsecond.
Anos rewrites history so the battle never happened.
Rimuru's Multiversal Memory Archive restores the timeline on his own terms.
Now they're both exhausted. The universe is cracking. Even Ciel pauses.
🌀 Final Clash
Rimuru creates a Reality Eater, something that can absorb even concepts like "victory."Anos condenses his entire existence into one attack, rewriting all possible outcomes into one final swing.
BOOM. The dimension collapses.
💀 Fade to White.
...and then both appear. Sitting at a café table. No damage. Just sipping drinks.
Anos: "You're not bad, slime."
Rimuru: "Likewise, discount Satoru Gojo."
They laugh.
🏁 Verdict — Who Actually Wins?CategoryRimuru TempestAnos VoldigoadHaxAbsorption, reality warping, soul controlConcept erasure, causality rewrite, logic killImmortalityYes — multilayered + Ciel backupsYes — resurrects from memory, history, nameIntelligenceCiel: god-tier AI-level intellectAnos: Intellect of a literal demon godRaw PowerMultiversal+ with evolutionMultiversal+ with overwhelming dominanceMain EdgeCiel's calculations + infinite adaptabilityVenuzdonoa + rewriting rules of battle
👉 Result:Draw, or Rimuru wins by Ciel out-processing Anos in the long game.But if Anos gets serious first and uses Venuzdonoa with full causal overwrite? Rimuru could lose before he adapts.
