Outside Chishiya's house, beyond the city limits…

A group was gathered anxiously in the courtyard.

Suddenly, a sound echoed across the sky.

[Individual Chishiya Shuntaro is beginning evolution into a Demon Lord]

[Once completed, all monsters under his lineage will receive blessings]

Everyone froze in shock.

"Wait… Was that the Voice of the World?"

"Chishiya-sama is evolving into a Demon Lord?!"

---

Voice of the World

In the worldview of [Tensura], the "Voice of the World" only speaks when major events happen—like a world shift, a new skill acquisition, or skill evolution.

It works like a global announcement system.

This is part of the canon setting, representing the will of the world.

---

At the same time—

The same message echoed within the Labyrinth.

[Individual Chishiya Shuntaro is beginning evolution into a Demon Lord]

The crowd inside the Labyrinth, still buzzing over the strange phenomenon above, was momentarily stunned.

Two seconds later—

The entire place exploded with noise.

"That was the Voice of the World?! Another Demon Lord's awakening?!"

"Wait… isn't Chishiya the name of the boss who runs this whole place?!"

"He's the Demon Lord?! It's over, we've all been duped! Was this all a trap?!"

"You're overthinking it. Why would someone that powerful waste their time setting up a trap for us nobodies?"

A merchant chimed in.

"Plus, he just saved our butts. I doubt he's the villain type."

"And honestly, if this city's under a Demon Lord's protection, isn't that a good thing?"

---

Inside the room.

Chishiya's consciousness floated in total darkness.

He couldn't move his body. His vision was completely blacked out.

Based on the situation, it looked like the evolution process had started.

"Let's see…"

Chishiya tried to open his interface panel.

No idea if the system was still functional during this state.

With just a thought—

A familiar display appeared in front of him.

Still works.

[Name: Chishiya Shuntaro]

[Core Staff: Megumin, Yunyun, Queen Ant, Aqua, Kazuma, Vanir, Wiz, Darkness, Rimuru, Frieren, Fern, Stark]

[Skills: Explosion Magic Lover, World's Shelter, Lone Wolf, Leadership, Knight's Body, Great Sage, Predator, Degenerate, Experienced Magician, Quickshooter, Explosive Blood, Careless One]

Once opened, a wall of skill data popped up in front of him.

With this many skills, maybe something new could be synthesized through the Degenerate trait.

"The Great Sage, start a mutation."

[Notice:]

[Integrating: Explosion Magic Lover, Lone Wolf, Experienced Magician, Quickshooter]

[Fusion complete]

[Acquired Unique Skill: Dominator]

[Effect: Retains all effects of the integrated skills. Also gains the ability to copy other people's magic.]

[Integrating: Knight's Body, Explosive Blood]

[Fusion complete]

[Acquired Unique Skill: Fighter]

[Effect: Retains all prior traits. Additionally, the user becomes more powerful the longer they fight, with the upper limit increased fivefold.]

Chishiya blinked.

"Not bad."

[Notice:]

[Demon Lord Evolution initiated]

[Reconstructing body. Evolving into a new species]

[Species Evolution: Human → Conceptual Lifeform]

[All physical functions massively enhanced. Can freely switch between physical and spiritual forms]

[New inherent skills acquired:]

1. Infinite Regeneration

2. Universal Perception

3. Demon Lord's Dominance

"Conceptual lifeform…?"

Chishiya blinked.

"Wait, I'm… not human anymore?"

That was… mildly concerning.

Conceptual lifeforms… those were basically gods in some isekai, right?

Settings vary between worlds, but in most alternate-world anime…

Gods were conceptual entities given divine power through the belief of mortals.

"Is that what I've become…?"

---

Then the Voice of the World chimed again in his mind.

[Notice:]

[Skill: Great Sage requests evolution from Voice of the World]

[Request approved]

[Evolving…]

[Failure]

[Retrying… Failed again…]

Chishiya: "The Great Sage's aiming for the Lord of Wisdom?"

In the original setting, the Lord of Wisdom was a top-tier ability evolved from the Great Sage, requiring the sacrifice of the Degenerate skill and a Demon Lord's blessing.

It granted insane mental computation, almost freezing time itself from the user's perspective.

It also inherited the effects of the Degenerate—allowing ability fusion, type conversion, and skill crafting.

Chishiya: "Sacrifice Degenerate and reapply for evolution."

If he could evolve into the Lord of Wisdom, it would be a massive power spike.

[…]

[Retrying… Success]

[Unique Skill: Great Sage has evolved into the Ultimate Skill: Lord of Wisdom]

Success.

Just as Chishiya was celebrating—

A new voice—softer, more feminine than the Great Sage—echoed in his mind.

[Requesting sacrifice of "Careless One" to evolve "Dominator"]

Chishiya paused.

Was the Lord of Wisdom offering guidance?

This wasn't part of the original storyline.

After all, Dominator was a skill synthesized from system rewards. Could that even be evolved?

"…Fine. Approve."

[…]

[Success]

[Unique Skill: Dominator has evolved into the Ultimate Skill: Lord of Ruling]

Lord of Ruling – Effects:

1. Ability Preservation – Converts acquired abilities into stored knowledge, allowing instant reuse.

2. Ability Replication – Analyze and copy other people's skills. (Ultimate Skills can only be copied at 50% effectiveness.)

3. Ability Gift – Grant copied skills to others or revoke them.

"???"

"Okay, that's actually busted…"

Chishiya's jaw dropped.

"Seriously? You're not even trying to be subtle anymore."

Even if analysis required time, the Lord of Wisdom could run thought processes at a million times the normal speed. Any ability could be cracked in seconds.

Granted, Ultimate Skills would take more effort…

But still—he could copy Ultimate Abilities.

Even at half power, that was absurd.

[Requesting sacrifice of "Leadership" to evolve "Fighter"]

Chishiya's eyelid twitched. "You again?"

He sighed.

"Fine. Last one."

In the original series, Rimuru only awakened with two Ultimate Skills.

Even among top-tier characters, having more than two Ultimate Skills was extremely rare.

"…Approve."

As soon as he said the word—

The Voice of the World responded.

[Success]

[Unique Skill: Fighter has evolved into the Ultimate Skill: Lord of War]

Lord of War – Effects:

1. Endless Growth – The longer the battle, the more all attributes increase. No cap.

2. Fighting Spirit – All monsters under your command gain the Fighter skill.

---

Third Ultimate Skill acquired.
