OBANAI

Obanai awakened on the hard floor of a dark cell. He reached for Kaburamaru, but realized that the pet snake wasn't there.

Huh?

"Kaburamaru? Are you hiding somewhere?"

Obanai stood up and strained his eyes to adjust to his dark surroundings. He found the cell door and saw that the space underneath the door was tall enough for a snake to go through it.

Oh no…

"Kaburamaru," he whispered as he peered underneath the door. He continued calling out for his pet until he heard footsteps.

He quickly backed away and laid back down on the floor, pretending he was asleep. Then, he heard the cell door unlock and turned to see Mujōna and a girl's silhouettes standing in the doorway. Mujōna lit a candle and stepped forward, revealing her voluptuous pregnant body. She had an evil, knowing smile spread across her beautiful face.

"Hello, Obanai," she sneered. "I'm pleased to see that you're awake."

"We had a deal," Obanai barked. "Let me see her!"

Mujōna tsked and continued smiling. "Oh, how sad that you didn't realize that she's right here…"

Wait, what?

Mujōna gestured toward the silhouette of the girl, beckon her to come forward. The girl slowly walked forward, the candle illuminating her.

Mitsuri!

Mitsuri's face was shadowed, adding an eerie contrast.

Yet, she looks so… different.

Taking a better look of her, Obanai realized that Mitsuri looked like a demon. She hard electric green eyes with slit pupils and a small horn on her forehead. Her claws were black, and she had a small heart marking on her cheek. A hungry look gleaned in Mitsuri's demonic green eyes that could only be translated as one thing: lust.

"Mitsuri… Y-you're a demon!"

"Yes, she is. Is that a problem, Obanai?" Mujōna laughed.

"You said that she was fine! I didn't know that you've turned her into an oni!"

"Hm, and I thought that love was blind," Mujōna sighed.

Mitsuri stood idly by her, never taking her eyes off Obanai.

She may be a demon, but she still looks cute. Hey, why is she staring at me like that?

Mujōna twirled a pink lock of Mitsuri's hair and came closer to her sharp ears. "Mitsuri, why don't you give our dear friend a proper welcome? I'm sure he'd like to see who you really are…"

With that, Mujōna placed the candle on the floor and left, leaving Obanai and Mitsuri alone in the shadowy cell together. Mitsuri stood immobilized as she continued staring at him.

"Mitsuri…? What's wrong with you? I mean, you're a demon of course—"

Before Obanai could finish, Mitsuri scratched his check. She tore off his bandages as his blood splattered on her face, making her even more aroused. Obanai laid frozen, shaking in terror.

This isn't Mitsuri at all!

"M-Mitsuri…"

"Arghhh!" Mitsuri shrieked as she pounced on him. She straddled him and began tearing off her clothes. The lecherous female demon tore her top to shreds, revealing her perky breasts. She breathed heavily, baring her fangs.

"Mitsuri, stop! This isn't you!" he exclaimed, shutting his eyes and looking away. He didn't want to see her body until they were married. "Mitsuri, snap out of it!"

"Look at me, Obanai," she said breathlessly, her voice filled with lust. She began grinding on his crotch, feeling his penis harden.

Obanai flinched at the sound of her voice and looked away, trying with all his might to not give in.

I must hold on. This isn't your girlfriend and you don't want to take advantage of her!

He clenched his teeth as he fought the temptation to look at her. In his mind, he knew that what was happening was so wrong, but it just felt so… right.

It felt so… human.

Obanai's body refused to listen to reason, his penis hardening and arousal spiking. He yearned to touch her how he did in all of his dreams.

"Look at me," she mewled. Mitsuri lowered herself directly on top of him and began licking his wounds.

"Mitsuri!"

"I need you badly!" she growled, biting his neck. Obanai howled in pain as his dick strained within his pants. The arousal and pain mixed together deliciously.

Mitsuri grinded faster and harder on The Serpent Pillar's groin area, feeling his length.

"Treat me like the whore I am!" Mitsuri hissed.

"No, you're not a whore! I'd never call you that. I think you're a beautiful woman, even if you're a demon!" he cried.

Like a wild animal, Mitsuri humped him. Pretty soon, Obanai couldn't resist her anymore. He began grinding with her in unison, both feeling each other's warm breath.

"Fuck me," she grunted with each thrust.

Obanai winced at the sound of her soft voice saying something so vulgar. Her obscenity inadvertently turned him on even more.

Mitsuri's cheeks were as red as apples, shadowed by the candlelit. Suddenly, she stopped grinding on top of him.

Why did she stop?

"Mitsuri…"

She then tore his pants off with ease, leaving his underwear untouched. Mitsuri stood over him with a mischievous grin, a sharp talon tracing over his flesh.

"I—"

"You want this, don't you, Obanai?" she said softly. Mitsuri pinched her pink nipple as she stared at his bulge. She sexily bit her lips, which drove him nuts.

"I—I—I," he stuttered.

"I want to feel you inside of me…"

Obanai's breath caught in his throat as she bent down to his penis.

I have to stop her.

Yet, he didn't.

The Serpent Pillar watched with anticipation as Mitsuri's mouth approached his groin area. With a forked tongue, she gently licked over his straining bulge.

"Oh my—"

He paused when he felt her sucking him through his underwear, her fangs lightly chewing on his eager flesh. Mitsuri did this for a few minutes, then suddenly yanked off the piece of fabric.

Obanai's dick sprang up like a weed. He was larger than average; a reasonable girth and over seven inches. Then, Mitsuri stood up and tore off her clothes, fully exposing her body to him. A small patch of pink hair covered her privates.

She's so beautiful…

Mitsuri turned then picked up something. "You must drink this to continue," she said, handing him a vial of blood.

"What is that, Mitsuri?" he said, wincing.

"Something that'll make everything so much better," she mewled.

Obanai hesitantly took the vial and opened it, smelling the strong scent of blood.

Demon blood.

"Mitsuri, I can't! I don't want to—"

"Obanai, if you love me, then you'll drink it. Become a demon with me!" she wailed, looking deranged. "We can be together for the rest of eternity!"

"Mitsuri, you've been corrupted. You're can still be a Demon Slayer, like Nezuko!" he pleaded.

Ignoring his pleads, Mitsuri opened the bottle and pounced on him, forcing the vial to his lips.

"Drink it, Obanai!" she screamed hysterically.

"Mitsuri!" he howled.

A meager drop fell onto his lips and he involuntarily licked them. Suddenly, he felt a sharp, stinging pain. Obanai jerked and screamed in agony as Mujōna's blood flowed through his veins.

Mitsuri crawled upon her convulsing lover, cuddling with him. "It'll be okay, Obanai. I promise."

Then everything went black.

MUJŌNA

"They sound happy," Muzan chuckled, referring to Mitsuri and Obanai.

"That's my handiwork," Mujōna replied. The two demons were eavesdropping on Obanai and Mitsuri, but stopped once it became too risqué.

"Your handiwork indeed," he purred, bringing her closer to him. Mujōna's stomach had extended even further, indicating that she'd give birth soon. "What do you want to do about the others?"

"We could put a drop of blood in their food; they have to eat. I'm out of clever schemes," she sighed.

"Well, I think that's a wonderful idea. We need to wrap this up quickly because I'd like to start our next phase," Muzan said.

"Oh yes, how could I forget? I assume you're going to take the reins on that part, hm?"

"Yes. I'd like you to stay here and focus on our little one. I promised you the Earth and I shall deliver." He kissed her deeply, stroking her large stomach. The couple cuddled in bed, pleased with how everything was tipping in their favor.

Suddenly, Mujōna had an idea.

"My Love, do you remember the crows we used to spy on the slayers?"

"Yes."

"Why don't we use one of them to deliver a message to our little friends?" she cooed.

"I'm listening…"

INOSUKE

"We're the only ones left!" Tengen cried out.

The slayers were inside of the Butterfly Estate, trying to figure out their next move. None of them had any idea what to do next and were losing hope.

"They just keep winning," Gyomei said, his head down.

"Who knows what kind of torture they're enduring? Oh, Kanao!" Shinobu sobbed. Kanae held her tightly, caressing her hair.

Giyu sat by a window, blankly staring at the outside.

"If we encounter them again, we'll surely be killed or abducted," Muichiro sighed. "This is getting too dangerous…"

"What are you saying, Muichiro?" Tengen sniffled.

"I'm saying that maybe… Never mind."

"Dude, just say it. Spit it out!"

"I said never mind!"

Inosuke laid down, staring at the ceiling. For the first time in a while, the beast slayer had taken off his mask. He thought of nothing but his abducted fellow slayers. An unspeakable anger boiled inside him, but he didn't know how to express it. Ever since Mujōna had so effortlessly slammed him against a tree, Inosuke hadn't been himself.

If a weakened demon could defeat me without even trying, am I even fit to be a slayer?

Inosuke remembered how he want even a certified Demon Slayer; he and Zenitsu just tagged along Tanjirou's side. He recalled the many times he would boast about his strength, but would always sustain the most injuries. Yet, his friends would always support him.

Tanjirou and Zenitsu are both gone… and I couldn't protect them.

Inosuke felt hot, stinging tears begging to be released, but he held it in. He contracted his muscles, his back still aching from Mujōna's attack.

I don't deserve to be with these skilled fighters; I am weak.

He then turned to his side to see Yushiro sitting in a corner, staring blankly at a wall. Yushiro had been like that for hours and no one had the courage to speak to him. The friendly demon had been acting strange since he returned, but everyone assumed it was because of the lack of blood.

Inosuke turned back around and sighed, listening to the other slayers trying to devise a plan, but mostly arguing.

"Muichiro, if you aren't in this, speak up!" Tengen roared.

"I am in this; they are my friends as well! I just think that… maybe we're going about this all wrong…"

"Oh, so how should we go about this, asshole?"

"Stop arguing! This is exactly what Muzan and Mujōna want; us breaking apart! We must stand together!" Kanae shouted.

Suddenly, the slayers heard the sound of a window being tapped. Giyu's eyes widened as he saw a crow tapping on the window. The crow had red eyes and a black envelope tied around its leg.

"Oh fuck, it's one of those demon crows," Gyomei sighed. "Don't let it in."

"Gyomei, I think this might be serious. There's no doubt that Muzan and Mujōna have something to say to us," Shinobu said.

"Alright, fine."

Giyu slowly opened the window and the crow entered, dropping the envelope in his lap. It sat perched, waiting for the envelope to be opened and read aloud.

The Water Pillar sighed deeply and began to read.

Dear Demon Slayers, I am pleased to inform you that our reign is about to begin. I also want you all to know that your companions are fine. Most of them have already been converted, but the others will soon turn as well. I'm sending you this message to propose an offer: if you surrender and become demons, you will not be killed or categorized with the lower class. Instead, you will be of a generous social standing and rank. I'd like an immediate decision!

Warm regards, Mujōna Kibutsuji.

The slayers were speechless for a few minutes.

"That evil—" Shinobu stopped herself, sobbing.

"Does anyone know how to say, 'fuck you' in twenty different languages?" Tengen said.

"As much as I hate to say it, I don't think we have a choice," Muichiro said.

"Are you fucking crazy?" Gyomei yelled.

"Muichiro…" Kanae gasped.

"They've already kidnapped almost half of us, and they're too powerful! Ignoring this opportunity and continuing business as usual would be suicide!" Muichiro exclaimed.

The slayers continued arguing with him, angry that he would even suggest such a thing.

Yet, deep down they knew that Muichiro was right.

"Giyu, please tell everyone that I'm right about this!"

Everyone turned to look at Giyu, who had been silent for most the time. The Water Pillar sighed and rolled his eyes.

"Oh, so now everyone wants my opinion," he said dully. He continued staring outside of the window.

"Tell them that we should take Mujōna's offer, then devise a plan to overthrow them. If we don't, we're as good as dead," Muichiro said.

After a few minutes of pondering, Giyu responded.

"Muichiro is right; there's no doubt that they'll kill us. We must call a ceasefire, but strike at the correct time. We should assemble all of the other Demon Slayers around the world and call for a secret attack."

The slayers nodded and huddled closer to Giyu, listening to the rest of his plan.

Yushiro's ears perked up as he listened to everything that was said.
