I Paired Up With a Woman From an Adventurer Matchmaking App, She Had Perfect Compatibility, But the Worst Personality. When Our Erotic Compatibility Exceeded 200%, She Became the Most Obedient Team Member at Night. - Chapter 7

“Even if I fall, a new ruler of darkness will inevitably rise to torment you humans once more. Until then, enjoy this fleeting peace while it lasts…”

With these final words, the Demon King dissolved into fine particles and vanished.
Left behind were Cordelia and I, completely unscathed and perfectly fine.

“…W-we actually defeated him. The Demon King.”

“…It’s true.”

We could only murmur in stunned disbelief.
…No.
No, no, no.
Wait a minute.
Seriously, wait.
Wait just a damn minute.
That Demon King—the ultimate final boss, radiating overwhelming power and presence—we just… defeated him so easily? Was that really okay?

“…H-He’s dead, right? He’s not just trying to lower our guard or something, is he?”

“I can feel the dense aura of magic power that permeated the area rapidly dissipating. I think he’s truly dead…”

Seriously?
But now that she mentioned it, the tingling, scorching sensation I’d felt on my skin moments ago had completely vanished.
What’s more, dazzling sunlight streamed through the gaps in the clouds in the Demon Realm sky, visible through the window.
The Demon Realm, ruled by the Demon King, was supposed to be a barren land perpetually shrouded in overcast skies.
The sensation of shattering the Demon’s core—the equivalent of its heart—still lingered in my palm.
Together with Cordelia, we dodged attacks in perfect coordination, deflected a barrage of spells, and burrowed our way into the Demon King’s inner sanctum.
I remember every detail of that battle vividly.
It was an unbelievable fight.
My body, still reeling from the intense struggle, refuses to calm its pounding heart.

“…Looks like we actually did it. Just the two of us, really.”

“…Yeah. We really did it, just the two of us.”

“We, with a 0.02% compatibility, actually defeated the Demon King.”

“We, with a 0.02% compatibility, actually defeated the Demon King, didn’t we?”

“…………”

“…………”

Behind us, a sudden groan broke the silence.

“Ugh… ugh…”

“Looks like I can finally stand…”

“Ouch… damn it, what the hell just happened…?”

Looking back, I saw the adventurers who had been struck by the Demon King’s magic attacks struggling to get to their feet.
Now that the Demon King had been defeated, the gravity manipulation magic that had been pinning them down had likely dissipated.
Perhaps because the Demon King had been fully occupied with his battle against us, there didn’t seem to be any adventurers who had lost their lives as far as I could see.
However, they all appeared physically exhausted from having endured an impossibly intense pressure throughout their bodies.
One of the adventurers shook the shoulder of a particularly large man—the party’s leader.

“Hey, Gael. Wake up.”

“Ugh… guh… Hah?! D-Demon King! You’ll pay for this, you bastard!”

Our hot-blooded leader, Gael, bared his fangs of animosity toward the Demon King the moment he opened his eyes.
Gael gripped his sturdy one-handed axe, which had remained undamaged despite the gravity attack, and raised it high above his head.

“I won’t forgive you for that sneak attack! You cowardly Demon King! I’ll split you in two with my axe—aaaaah… huh?”

But as he rose with a roar, the Demon he sought was nowhere to be seen.
Noticing the empty throne at the center of the Demon Lord’s Chamber, Gael frantically scanned the room.
Yet no matter how wide he opened his eyes and searched, not even a trace of the Demon King remained.
Instead, he found only me and Cordelia, standing perfectly clean, not a speck of dust on our pristine armor.
Gael froze, his prized one-handed axe still raised high in the air.
Then, as if all his previous momentum had vanished, Gael asked hesitantly,

“The Demon King…?”

“He’s dead.”

“Dead?”

The valiant leader echoed the word in disbelief.
Gael slowly lowered his one-handed axe, its target now gone.

“…W-what happened? While we were unconscious…”

He asked the obvious question.
Of course, he’d be curious.
After all, we’d charged into the Demon Lord’s Chamber only to be immediately knocked unconscious by a magical attack. When we finally regained consciousness and bravely raised our weapons, the Demon King was already dead.
Logically speaking, it was utterly incomprehensible.
So it was only natural that they were desperate to know the truth.

“Sorry, I don’t have time to explain right now.”

“Huh?”

“Let’s go, Cordelia.”

“I know without you telling me, Kent.”

“Ah, w-wait…”

I brushed aside Gael’s hesitant hand and left the Demon Lord’s Chamber with Cordelia.
Behind us, we could hear the groans of the adventurers regaining consciousness.
Some might need assistance, but they could probably manage among themselves.
The Demon King was dead.
There shouldn’t be any problem leaving the rest to them.
