In a dense forest nearby, traces of a demon appeared in an unremarkable village. Because a towering pine tree stood at the village entrance, it was aptly named Matsushita Village, and all the villagers took Matsushita as their family name.
"Hashira-sama, you've finally arrived," an elderly man with white hair said, leaning on a cane as he emerged from the village entrance to greet the elite members of the Demon Slayer Corps. Two young villagers accompanied him.
Mitsuri Kanroji scanned the surroundings cautiously, her brows slightly furrowed. Shinobu Kocho gave a faint smile and nodded toward the old village chief.
"Village chief, could you tell us the details?" Shinobu asked, her voice soft, warm, and soothing, instantly calming the trembling old man.
"Hashira-sama, it started about a month ago when we first noticed signs of a demon. I believe it's been in Matsushita Village for nearly that long. A month ago, young girls and women began disappearing from our village. After we found traces of the demon a few days ago, three more vanished in quick succession. We had no choice but to call for your help. That demon is too cunning, we can't even track it," the white-haired village chief explained, shaking his head helplessly. A trace of pain crossed his face. Just yesterday, his 18-year-old granddaughter had been taken by the demon.
Mitsuri stepped forward. "There's definitely a stench of a demon here, no mistake about it," she said, crossing her arms over her chest, which pressed her ample cleavage deeper within her uniform.
Shinobu nodded and turned to comfort the village chief. "Don't worry, we're here to handle this. Do you have any other clues?" she asked gently.
"Not much, I'm afraid. But a few days ago, one of our hunters went up the mountain to hunt and said he heard a woman's cries for help near a cave on the waist of the second mountain ahead. He went inside but found no one. That's the only lead we have, and I'm embarrassed it's not more helpful," the old village chief replied, his face flushing with shame over the vagueness of his information.
"Alright, we understand. For the next few days, please ask the villagers to avoid going outside. If we find anything, I'll let you know right away," Shinobu said reassuringly before exchanging a glance with Mitsuri.
"Let's search the area first. We'll meet back here in an hour. If we don't find anything else, we'll check out that cave," Shinobu suggested, starting to walk off. Her slender waist swayed slightly under her full, fertile hips, exuding a subtle charm with each step.
Mitsuri nodded in agreement and headed in the opposite direction, her large breasts jiggling faintly with her movements.
By the time Shinobu and Mitsuri reached the cave the village chief had mentioned, it was nearly nightfall. A bright moon hung in the sky, casting a faint glow into the dense forest.
"This should be it. The demon's stench is getting stronger," Mitsuri said, wrinkling her nose to confirm her suspicion.
Before them stood a cave nearly ten feet tall, its interior pitch-black and impenetrable even with the torches they held, which only illuminated the entrance.
"Something feels off, it's almost too easy," Shinobu remarked, frowning as she scanned their surroundings with heightened alertness.
"I'll go in first. If I'm not back in half an hour, don't come after me. Go get backup, got it?" Shinobu instructed, tightening her grip on her four-leaf Nichirin Blade. Her breathing grew heavy as she steeled herself, her Insect Breathing primed and ready to react to any threat.
"Okay, be careful. If there's trouble, shout for me, I'll rush in right away," Mitsuri replied solemnly, her full breasts bouncing noticeably with her nod.
Shinobu entered the cave slowly, her senses on high alert. After a thorough search, she found no useful clues. Glancing at the time, she realized it was nearly up and started heading back.
Her guard lowered slightly as she stepped out of the cave. By now, the bright moon had slipped behind thick clouds, and a thin mist drifted through the forest.
"Mitsuri?" Shinobu called, emerging from the cave. Her slight relaxation turned to unease. Mitsuri Kanroji was gone!
Suddenly, Shinobu felt a wave of weakness wash over her body. Her legs gave out, and she collapsed helplessly to the ground.
"Well, well, isn't this Shinobu Kocho-sama? How do you like the sedative I crafted just for you, mistress of the Butterfly Mansion? Pretty potent, huh?" a childlike voice said, reaching Shinobu's ears. She forced her eyes open and saw a figure ahead, a child barely three feet tall.
But this child's skin was an ashen blue, and his face bore the unmistakable markings of a demon. Oh no! Mitsuri?! Shinobu thought, her body trembling as the realization hit her. In the instant before she passed out, her only concern was Mitsuri's safety.
Inside the vast, empty cave, Shinobu and Mitsuri hung suspended in the air, bound tightly by thick ropes. Nearby, the demon from earlier waited patiently for them to wake.
Mitsuri stirred first, her eyes fluttering open in confusion before blinking twice. "Hm?" she mumbled, the strange sensation on her body snapping her fully awake.
"Shinobu?!" she gasped, spotting Shinobu dangling from ropes right in front of her. Looking down, Mitsuri saw herself similarly restrained.
They'd been ambushed! Mitsuri tried to summon her Love Breathing, but as her blood began to circulate, a strange sensation flooded her body.
"Awake, huh? Heh," a childlike voice cut through the air beside her. Mitsuri's face flushed an odd shade of red, her breathing quickening.She turned her head and saw him. "An honor to meet the legendary Shinobu Kocho-sama and Mitsuri Kanroji-sama.
Allow me to introduce myself, I'm Tongui, the Child Demon," the demon said, stepping closer to Mitsuri. Barely three feet tall, he flashed a lecherous grin, his scarlet tongue flicking out to circle his lips as his lustful gaze locked onto her body.
"Let me go!" Mitsuri demanded, struggling as her face burned red.
"Let you go, Mitsuri-sama? Are you kidding? I'm a demon, and you're a Hashira of the Demon Slayer Corps. You really think I'd just release you?" Tongui replied, bursting into mocking laughter at her demand.
His taunts made Mitsuri's face flush even deeper. She tried summoning her Love Breathing again, but that strange sensation surged through her once more, making her body quiver uncontrollably.
"No point in trying, Mitsuri-sama. I've hit you with my Blood Demon Art. The more you use your Breathing Technique, the more sensitive your body gets. Feel it yet?" Tongui chuckled, eyeing Mitsuri as she dangled face-down, about a foot and a half off the ground.
A small, ashen hand reached out, slipping through the opening of her uniform at the chest and expertly pinching her nipple.
"Oh? Already hard, huh? You're such a slut, Mitsuri-sama," Tongui said, kneading her nipple. The sudden jolt of unfamiliar pleasure made Mitsuri tremble violently. She tried to writhe free, but suspended in the air, she couldn't budge.
"What do you want?!" Mitsuri shouted, unable to use her Breathing Technique. Her body felt weak and powerless to resist, despair creeping in.
"You think the Demon Slayer Corps will ignore two missing Hashira?! Let me tell you, if we don't report back by tomorrow, they'll send more to wipe you out. Let us go now, and we'll pretend this never happened," she argued, making one last desperate attempt to intimidate Tongui with the Corps' might.
"You think it's a coincidence I'm here? I was waiting for you two. And don't worry, I'll let you go," Tongui said with a wicked grin, leaving Mitsuri stunned. Let us go? she thought.
"Don't trust him, Mitsuri! We're breaking out now!" Shinobu interrupted, waking up at that moment. Hearing Tongui's words, she refused to believe him. Her voice, though soft, carried fierce determination.
She steadied her breath, activating her Insect Breathing. "Shinobu!! Don't use your Breathing Technique!!" Mitsuri shouted in warning, but it was too late.
A flush of pink spread across Shinobu's face as that strange pleasure surged through her too. Ignoring it, she pressed on with her Insect Breathing.
Tongui sneered and stepped toward Shinobu. He gazed down at her, watching as the flush on her face deepened to a full blush, her trembling escalating into shudders.
After a dozen seconds, Shinobu's body jolted violently, and a soft, sultry moan slipped from her lips.
"Feel good? Really good, right?" Tongui said, his face twisting with disdain. "My Blood Demon Art heightens a woman's sensitivity. While you were out cold, I cranked yours up fifty times. Even the slightest movement sends pleasure through you. Breathing Techniques? The faster your blood flows, the more intense it gets. See that rope digging into your pussy? I prepared it just for you," he explained, pointing at the rope wedged against Shinobu's crotch. It rubbed her clit with every shift, and already, a damp spot had formed, quickly soaking through and leaving her groin visibly wet.
Tongui grabbed one end of the rope and tugged it lightly. The cord scraped rapidly against Shinobu's clit, unleashing a flood of pleasure that overwhelmed her petite frame. Her body shook as the sensation coursed through her, forcing out loud, desperate moans.
