Dungeon Raid Mission Request
Miyeon had been feeling strange symptoms lately—her body was hypersensitive in a way that was utterly abnormal—but even after consulting her personal physician, she couldn't pinpoint the cause. She chalked it up to psychological issues.
"Heh heh heh. By now, her sensitivity must be several times higher."
The culprit behind Miyeon's heightened sensitivity, Kang Cheonhu, smirked wickedly as he imagined her predicament. He knew her body had become so excruciatingly sensitive that even everyday activities would feel torturous.
"Miyeon, you're mine."
Kang Cheonhu had resolved to claim her, his lips curling into a sleazy grin. Lying there with his legs spread, two stunning beauties were eagerly slurping away at his cock between his thighs.
...
Though Miyeon sensed the abnormality in her body, she suppressed it through sheer willpower, continuing her daily routine and hero duties as usual. In truth, her sensitivity had spiked so dramatically that an ordinary person couldn't have managed basic life. But Miyeon possessed the exceptional physical and mental fortitude befitting an S-rank hero.
Of course, the other members of Team Valkyrie hadn't noticed anything unusual about her either. She hadn't told them about her body's changes, and while they sensed she seemed a bit sexier lately, that was the extent of it. Miyeon herself felt too embarrassed to admit her sexual sensitivity had gone haywire, so aside from her doctor, she hadn't breathed a word to anyone.
(Ugh... Sis is making my dick hard again...)
But Jinseok was constantly tormented by the erotic aura radiating from his sister Miyeon. Just approaching her made it nearly impossible to suppress his painfully throbbing erection. He didn't think her vibe had changed; instead, he figured he was the weird one for getting so turned on by his own sister, drowning in self-loathing and guilt.
And so, with Miyeon's secret physical issue being the only wrinkle, Team Valkyrie had been cruising smoothly—until a new challenge loomed on the horizon.
...
"A dungeon raid mission request?"
"Yes. The Monster Countermeasures Headquarters has commissioned us to conquer the dungeon."
Miyeon learned from her secretary, Oh Hyeji, that the Monster Countermeasures Headquarters had sent a dungeon conquest request.
Dungeon raids—commonly called "raids"—involved preemptively predicting a Spacetime Shock, then punching a small Gate into the monsters' dimension before the shock hit and monsters spilled onto Earth. That parallel dimension was dubbed the "dungeon," and the core mission was to destroy the dungeon core forming the sub-dimension inside it, then escape before the whole thing collapsed.
Raids were a high-reward strategy: wipe out the monsters in their waiting pocket dimension before they ever reached Earth, minimizing damage to the planet. Naturally, this meant nearly zero collateral on the surface—just pure monster extermination.
But raids were equally high-risk. Gate environments and monster densities could be estimated from the Gate's size and traits, and unmanned scout drones were often deployed for recon. Still, intel sometimes went awry—overpowered monsters beyond expectation, or dungeon interiors hostile to humans in ways that crippled combat. And escape options were limited: on Earth, you had backup from other heroes or the military, or at worst, retreat. Inside a dungeon? Only the Gate offered exit, making dire straits a nightmare.
Dungeon raids were far tougher than standard post-Gate monster hunts, reserved exclusively for top-tier heroes.
"The target Gate is expected to trigger a Spacetime Shock soon and open on Earth. Given its scale, we're anticipating a massive boss-level monster. Its location near a major city means opening it could cause catastrophic damage."
"Got it. We'll throw our full strength at this raid."
With three S-rank heroes, Team Valkyrie had the chops for dungeon raids. Miyeon accepted the mission after the brief rundown.
...
"A dungeon raid?"
"A raid? Isn't that super dangerous?"
Jinseok and Serin were stunned to hear Miyeon announce they'd take the raid mission. Serin, despite her talent, lacked experience and had never done a raid, so she was scared stiff.
"It's risky, sure, but with our current skills, I think we can handle it. We'll prep thoroughly, of course. But we're a team—if not everyone's on board, we don't go."
"Yeah. With three S-ranks, there's hardly a dungeon we couldn't clear."
Miyeon was set on the raid but, as leader, sought full team buy-in. Ye-eun agreed with her. Team Valkyrie boasted three S-ranks with perfectly balanced abilities—ideal raid composition.
"If you sisters say so, I'm in."
"Yeah... Me too, then. Sounds okay."
In the end, Jinseok voted yes for the raid, and Serin followed suit. With Miyeon and Ye-eun vouching for it, the less experienced juniors had no reason to object.
"Alright. Full raid prep starts today."
Miyeon declared prep underway. Team Valkyrie's dungeon raid was locked in.
...
Rumble rumble rumble!
A massive trailer emblazoned with Team Valkyrie's logo rumbled toward the raid Gate site. Truck-sized, it featured tank treads instead of wheels for rough dungeon terrain post-entry, packed with gear and supplies inside.
"Gate setup's done."
Jinseok handled driving and operations. His special forces stint made him a pro with military hardware. Nearing the site, he spotted the huge raid Gate under assembly.
The raid Gate—a machine to artificially link to the monster dimension—resembled a giant special-alloy ring, wired to countless cables and electronics. Scientists tinkered with adjustments nearby. Opening dimensional portals demanded immense power and intricate principles, but established tech meant sufficient budget, manpower, and gear made it routine.
"Monster Response Special Forces are here too. Takes me back to my army days..."
For contingencies like monster breakthroughs, troops ringed the Gate—special forces with tanks and attack choppers. As an ex-member, Jinseok felt nostalgic seeing them.
The Gate was tunnel-sized, big enough for their trailer. The team dismounted upon arrival, awaiting op commencement—not diving in blind.
"Team Valkyrie leader, Yoo Miyeon? Major Jang Tae-seung, op commander."
"Yes. Hello."
"Gate activation prep is on schedule. No worries."
"Good to hear."
A burly soldier in uniform approached Miyeon for a handshake—Jang Tae-seung, special forces CO. They chatted as they shook.
(Whoa? That's Captain Jang? Made major, huh.)
Jinseok spotted the major and instinctively saluted. Jang had been his superior during service.
