My Yandere Girlfriend Hiding in the Dungeon Kills Me Over and Over Again - Chapter 165

Chapter 165   Dark Magic

“No way… I can’t believe Sage Nyau was hiding something this interesting. But that doesn’t mean you can beat me.”

With those words, Elsie snapped her fingers.

In an instant, Lyune’s left side shattered into fragments as if torn like paper. Red droplets sprayed across my cheek.

“This can’t be happening…”

I couldn’t help but mutter in disbelief.

The word “god” that she mentioned earlier now made all too much sense. There’s no way anyone could win against this.

—At that moment of utter despair, something incredible happened.

A black mist rose from Lyune’s body. In the next moment, her shattered left side began to regenerate before our eyes—muscle bulging, bones extending, skin covering.

“…What?”

Elsie’s stunned voice echoed. Her eyes widened, unable to hide her obvious shock.

Yes, Lyune, who should have been fatally wounded, had completely regenerated in an instant.

“Second Tier—Shadow Claw.”

Lyune’s low voice resounded once more. This time, black claws sprouted from both of her hands, lunging at Elsie like a beast.

“I told you, it’s useless!!”

With a scream, another part of Lyune’s body exploded. Yet, in an instant, her flesh regenerated, allowing her to continue her relentless assault.

“Third Tier, Shadow Ring.”

“Fourth Tier, Shadow Spear.”

One after another, Lyune unleashed her magic.

In response, Elsie roared, “Shut up!!” trying to nullify the magic through explosions.

No matter how many attacks she endured, Lyune regenerated immediately and continued casting spells.

It was a barrage of insane, relentless attacks.

Elsie countered each one with explosions, but the sheer volume was overwhelming—she couldn’t block them all.

“Why…? Why must I, a god, struggle this much against the likes of you?!”

Elsie’s furious scream echoed. A black blade from Lyune’s attack grazed her face, drawing blood. But in an instant, Elsie erased the wound—she, too, possessed the power to ignore any injury.

“That’s why… in this space, you can’t possibly defeat me!!”

The next moment, Lyune’s body was utterly shattered by Elsie’s attack. But as black mist swirled, her body regenerated, and she unleashed an even more ferocious barrage of magic. Overwhelmed, Elsie’s defenses faltered for a brief instant, allowing a spear of shadows to pierce her chest.

“Guh…!”

Elsie tried to heal the wound, but Lyune’s relentless attacks gave her no chance. As if refusing her even a moment’s respite, spell after spell rained down. Their blood scattered through the air, staining the floor a deep red.

At this point, it was no longer just a battle of magic—it had become a brutal, monstrous clash of raw power.

“Why… why why why?! This is my domain! You’re not supposed to defy my will! That’s not allowed!!”

Elsie’s shriek rang out, almost like a cry of despair. The confidence in her eyes had long since vanished. In its place was something else—pure madness, and beyond that… fear.

“Tenth Tier—Magicide.”

Lyune’s voice resonated as if rising from the depths of hell itself.

It carried a depth unlike anything heard before. In an instant, the very space around her twisted into something resembling an abyss. The magic surging forth from it was beyond anything human comprehension could grasp.

“The Tenth Tier?! That’s the highest tier of magic—you can’t possibly—!”

Elsie’s voice trembled. Gone was her arrogance, replaced entirely by terror. The space around Lyune distorted like a black void, releasing waves of darkness that pulsed outward. Each time Elsie tried to counter, the black waves multiplied, growing faster, stronger, more relentless.

“Just… what are you…?”

Elsie’s final words faded into the void. The so-called god had been powerless before such overwhelming magic. The black waves devoured her body, consuming her very existence as though she were nothing more than prey cornered by a predator.

Like a candle’s flame flickering out, Elsie melted away, her being erased entirely by Lyune’s spell.

Before I knew it, the heart Elsie had stolen from me had returned to my chest, and my legs—shattered beyond repair—were whole again. I couldn’t begin to understand the cause, but one thing was certain: Lyune had saved me.

Yet the relief I felt froze in an instant.

Lyune slowly turned to face me.

Or rather, the being that had once been Lyune.

She gazed down at me with chilling eyes. A jet-black horn now jutted from her forehead, and her pupils had transformed into the thin slits of a reptile. The maid outfit she had worn was in tatters from the fierce battle, barely clinging to her frame, revealing glimpses of her bare skin.

Her gaze no longer held the warmth of a human. The way she looked at me was that of a complete stranger.

“…Lyune, is that you?”

I called out to her, my voice tinged with unease.

Her form was now far from human, yet surely her heart remained the same. After all, she had fought to protect me—hadn’t she?

“Dark Magic, First Tier—Shadow Blade.”

She spoke in an eerily calm tone.

And with that, my hopes crumbled into dust.

For an instant, Lyune’s golden eyes flashed crimson—feral, inhuman.

The next moment, she lunged.

A jet-black blade swung down toward me.
