With a dizzying spin, I was teleported from the treasure vault straight to my bedroom.

I was still wearing Feyn Senior’s lingerie. The bra was far too large—more revealing than concealing—and her lingering scent clung to my skin.

"Hmph… Everything… is proceeding exactly as planned…" I murmured, though my cheeks burned at the memory. I’d originally intended to negotiate a proper retreat, gifting her that armor to wear. But in the end… the result was the same. As for the process…

Just thinking about it made my face scorching hot. For a boy like me, losing my first kiss to a goddess like Feyn Senior should’ve been a dream come true. But I never wanted it to happen like *this*!

Why did the goddess have to be the one taking charge? Shouldn’t it have been me, under the moonlight, lifting her chin…? Why was I ignored as a boy, only to be chased by older sisters after becoming a girl? Was my personality… more appealing as a girl? No… I don’t like this at all. Feyn Senior, you’re awful! So unfair!

I collapsed weakly onto the bed.

But the plan was already in motion. I had to push through. Even after this humiliation, I needed to stay sharp!

I got up. I didn’t shower to wash away Feyn’s scent—not that I’d ever admit I liked it. I kept it as a reminder: my carelessness had nearly ruined everything. I didn’t even change out of her lingerie. Instead, I slipped into my gothic princess dress, tidied my hair, and vanished in a flash to Sulia’s room on the sixth floor.

Sulia was waiting.

Dressed in a crisp red noble’s jacket and white fitted trousers, she looked strikingly dashing.

Her eyes pierced through me as she smirked. "Well? Your Highness? How did it feel to be forcibly kissed by your enemy?"

"Eh?!" I covered my mouth, mortified. I wanted to sink into the floor.

"Don’t look so shocked, Princess," Sulia teased. "That blood-shadow bat was *my* spell. I saw everything in that little booth. Honestly, even *I* felt awkward watching you two cuddle."

I froze. Regret crashed over me—I’d forgotten the bat was still watching!

My voice trembled. "S-Sulia… Sister… no one else saw, right?"

"Don’t worry. I cut the feed from the War Room the moment things got… embarrassing." Only then did I breathe again.

"Th-thank you… And Sulia—I *order* you. Not a word of this leaks out!" I commanded sharply.

Sulia just waved me off with a chuckle. "Yes, yes. Of course, little princess."

Silence stretched between us.

Time for the next step of my plan. Yet here I stood, hesitating.

Why? Even after Feyn Senior’s… teasing… I wondered if she had her reasons. She’d wept so bitterly for that girl, Xueno. Was it right to manipulate her like this?

True, the kiss wasn’t my choice—but I *was* deceiving her with this borrowed body. What right did I have to resent losing my first kiss? Wasn’t this my own doing? My just punishment?

If I could… I wouldn’t want to trick her at all.

But I was the Dungeon Princess. I had to protect this place.

Not out of nobility. Not out of greatness. I did it for myself.

A princess without her castle? Her fate would be far crueler than a pauper’s.

I only wanted to guard this Undercity—the only home that had ever sheltered me!

"Sulia! Let’s begin the next phase." I steeled myself.

"Hmm. Very well, Princess Kuroti. Since you’ve decided…" Sulia’s voice dripped with amusement. "I shall proceed."

She led me to the adjacent room. Everything was prepared.

Bessdaitiel waited in a maid uniform three sizes too small. In the center stood a high-backed chair with wide armrests.

"Sit," Sulia commanded like a queen.

"Don’t order me around!" I snapped—but soon found myself sinking into the chair. Its deep, reclined back left me defenseless, sprawled like a patient on an examination table. Sulia and Bessdaitiel each took one of my hands.

This chair was meant for a maid—not me! But thanks to Sulia, I’d worn that armor myself…

I sighed. I was at their mercy now.

Sulia waved her hand. The blood-shadow bat’s vision flickered to life.

On screen, Feyn Senior charged at the front lines. Her near-naked body gleamed beneath sparse black armor as she cleaved through undead hordes, leading the expeditionary force’s retreat. Purple Shengshi arrows shattered against a faint, crystalline barrier before they could touch her.

Truly formidable. With armor second only to a Divine Artifact, no one could harm her.

She fought harder, sweat glistening on her skin—powerful, untouchable… even if the armor looked utterly shameless.

"Begin," I said, my voice tight.

"*Hnn… ah… ahaha…*"

Instantly, Feyn’s movements faltered. She nearly stumbled under a skeleton’s blow, saved only by her armor’s defense.

"*Stop!*" I gasped.

Her motions snapped back to normal. She fought on bravely.

Her holy shields and courage auras for her allies were fading. Feyn parried a skeletal strike, retreated behind her comrades, and began chanting to renew her blessings.

I was still catching my breath, but a vengeful smirk curled my lips. "Continue. Feyn Senior… you humiliated me. Now you’ll feel the same shame."

Bessdaitiel and Sulia lifted my arms again. Feathers danced along my inner elbows, tracing paths to my armpits…

"*Ahahaha! AHAHAHAHAHA!*" The Dark Princess’s delicate body couldn’t withstand such tickling. I writhed, laughter bursting uncontrollably.

*Pfft—*

On screen, Feyn choked mid-chant. One moment radiating holy aura, the next—giggling like a schoolgirl. Around her, warriors bled and strained without her blessings.

Soldiers stared in disbelief. How could their revered leader laugh *now*?

Feyn’s face twisted in panic. "N-no! It’s not—I don’t… *Ahaha!* Hnngh… *heehee…*" She clamped a hand over her mouth, but the giggles wouldn’t stop.

Whenever she calmed enough to restart her chant, I signaled Sulia and Bessdaitiel. Feyn would jerk, distracted again—utterly unable to cast.

Feyn, the Empire’s legendary Temple Knight, was failing her troops. Her inexplicable laughter shattered morale.

Time to escalate.

"Phase Two," I ordered.

"Understood," Sulia and Bessdaitiel chimed, almost gleeful.

They seized my ankles, hoisting my feet onto the chair’s armrests. Off came my heels and stockings, baring my pale soles. Those cursed goose feathers returned—now tracing maddening circles on my tender arches.

Feyn’s expression turned exquisite.

Inside her black metal boots—part of the Fallen Lady Angel armor—she felt every unbearable stroke.

"*AHAHAHA! AHAHAHAHA!*" The noble knight collapsed, clutching her feet, laughing hysterically on the ground.

Her willpower might have endured physical tickling… but this armor transmitted *my* raw sensations. Since I didn’t resist, neither could she.

To her troops, it looked like possession. Morale shattered.

Veteran warriors and mages activated precious teleport stones—items worth half a high-rank knight’s fortune—to flee. Others were swallowed by the skeletal tide.

Loyning, heartbroken, pulled out a Tier-4 teleport gem. She rushed to Feyn’s side. The knight was a mess: laughing one second, blushing and grinding her thighs together the next, barely fending off attacks.

"Guild Leader! What’s wrong?! Never mind—let’s retreat! Most have already fled!"

"Sorry, Loyning… I… we…" Feyn fumbled with her teleport stone, but giggles and shivers kept breaking her focus. Loyning, refusing to abandon her, stood firm beside her.

I leaned forward. "Now, Jester Bull. Your entrance."

The earth heaved. A colossal black bull—Jester Bull, the eighth-floor guardian—erupted from the ground atop an even mightier Cave Lord. The beast trampled Feyn’s remaining loyal knights like chicks. Jester Bull leaped down, its axe sending Loyning’s weapon flying and slamming her to the dirt.

As for Feyn Senior? She might have matched Jester Bull at full strength. But now—writhing on the ground between fits of laughter and breathless whimpers—she was already defeated.

A swarm of Scyllas followed the Cave Lord from the tunnels. These ninth-floor demons—tall, curvaceous, with blue skin and black wings—descended on Feyn and Loyning. They disarmed them, then bound them tightly with unbreakable ropes.
