After returning toDemon Slayer HQ, Rajastrolledinto his undergroundmad scientist lair, where two very unluckyex-demonswere waiting for him.

Inside theEnchanted Containment Cells,Dakiwasthrashing around like a possessed monkey, slamming her fists against the walls whileGyutarojust sat therecalmly, watching his sister waste her energy.

"What kind of prison is this?!" Daki screeched. "I’ve shredded through walls, decapitated men, and—WHY CAN’T I BREAK THIS STUPID BOX?!"

Gyutaro sighed."Because you’re dumb, Daki."

Before Daki couldexplodeat her brother, Rajastrode in, wearing awhite lab coat, thickround glasses, and anevil grinso exaggerated that it belonged in acartoon villain audition.

"Welcome, my dear subjects! Today, I present you with a simple choice: One of you will live a peaceful life, free from Muzan’s control... and the other? Well, the other will be my... ’experimental subject’ for an undetermined amount of time, possibly forever."

Gyutaro and Dakifroze.

"What?"Daki snarled."You think we’re just gonna let you decide our fate?"

Gyutaro, however, didnothesitate."Do whatever you want with me. Just don’t touch Daki."

Daki’s mouthfell open.

"WHAT?! BROTHER, HAVE YOU LOST YOUR UGLY-ASS MIND?!"

Gyutaroglaredat her."Daki. Shut up."

"NO, YOU SHUT UP! I WON’T LET THIS—!"

"Daki,"Gyutaro interrupted, his voice calm."I mean it."

The roomfell silent.

Gyutaro then turned to Raja."Swear it. Swear on your trident that you won’t touch her."

Rajachuckled,"Damn, you’re serious about this, huh? Fine. I swear on my mighty trident that I will leave Daki alone."

"Hah! You hear that, Daki? You’re safe,"Gyutaro said.

"LIKE HELL I AM!"Dakismashed her fists against the cell wall, but it waspointless.

Raja, grinning like asadistic teacher before a pop quiz, slid asyringeinto Gyutaro’s cell.

"Go ahead, champ. This one’s for you."

Gyutaro took it without hesitation.

"BROTHER, NOOOO—!"

STAB!

The injectionslammed into his neck, and within seconds,Gyutaro’s body spasmedas the vaccineburned through his system.

The demon inside him screamed.

"AARGHHHHH!!!"Gyutaro convulsed, veinspulsing with golden light.

Daki wascrying,kicking the cell,throwing a tantrum like a kid denied candy at a store.

And then...

Silence.

Gyutarocollapsed,completely human.

Daki, panting, turned to Raja,her face red with rage and tears."WHAT. DID. YOU. DO?!"

Raja casuallyinjected Dakibefore she could say another word.

"G’NIGHT!"Raja chirped asDaki crumpled like a deflated balloon.

A week later, thesiblings woke up—andimmediately started bickering.

Gyutaro, nowan absurdly attractive teenage heartthrob, checked himself out in a mirror.

"...What the hell? Is this me?"

Daki, meanwhile,glared at him with tears in her eyes.

"HOW COULD YOU LEAVE ME LIKE THAT?! YOU BETRAYED ME, YOU UGLY—I MEAN HANDSOME TRAITOR!"

"Calm down, Daki—"

"DON’T ’CALM DOWN’ ME! LOOK AT YOU! Now some floozy is gonna steal you away, and I’LL BE LEFT ALL ALONE!"

Tamayo entered the roomwith the grace of a tired mom.

"Enough, children."She grabbed both theirears and dragged them forward.

"OW OW OW OW!"both of themscreamed.

"You two are human now,"she said,glaring like a disappointed teacher."Which means you will act likenormalhumans or so help me, I will personally make you wish you were still demons."

Gyutaro and Dakigulped.

Meanwhile,Raja was busy elsewhere...

Using hisshadow clones, Rajascouted Mt. Kumotori—the place whereYoriichi Tsugikunihadburied his wife, Uta.

And there it was.

TheBlue Spider Lily.

Theholy grailof Muzan’sstupidly long-lived existence.

Rajasmirked, storing the plantsinside his Dimensional Inventory, where they wouldgrow safelyaway fromdemonic tampering.

"And now... time to set the trap."

Back atDemon Slayer HQ, Rajagathered all the Hashira.

Rengoku, ever the loud and passionate warrior,slammed his fist on the table.

"IT’S FINALLY TIME TO BURN THAT ABOMINATION TO THE GROUND!"

The otherscheered.

Raja explainedhis master plan:

Lure Muzanusing the Blue Spider Lily.Make him believe it’s unguarded.Have an army of Demon Slayers (and Raja’s 100 Shadow Ninjas) waiting.End him once and for all.

The Hashirawere fired up.

And Muzan?

Well... he hadno ideawhat was coming.

Somewhere inYoshiwara’s Entertainment District, abeautiful womanwith pale skin sat in a luxurious room.

She hadraven-black hair,plum-red eyes, and asoft smile.

And by beautiful woman, I mean...

It wasMuzan Kibutsuji.

Dressed like a lady.He is here looking for clues of the missing Daki and Gyutaro.

Sipping tea.

Raja, disguised as adrunk, obnoxious noble,staggered in, loudly laughing.

"Ahhh! What a fine night! Where’s the pretty lady? Let me see the—"Raja’accidentally’ droppedaphoto diary.

One of Muzan’sservantspicked it up.

Muzan,rolling his eyes, absentmindedlyflipped through the pages.

Roses, daisies, tulips, meh—

And then.

Hefroze.

Aphoto of the Blue Spider Lily.

With alocation.

Muzan’shands trembled.

It’s real.

The drunk, is a flower enthusiast, collects information on flowers and trees, documenting where they grow in his diary to eventually create a book. While searching for flowers in the mountains, he discovered Blue Lilies, took a photo of them, and wrote about them.

However, some men in black uniforms with katanas arrived, declaring the mountain a restricted area and private property. He was forced to leave the mountain, and in his anger, he Came to the entertainment district to let off some steam.

Muzan summoned every single demon under his command toInfinity Castle.

"We attack at Dusk."

Little did he know...

TheDemon Slayer Corps was already waiting.

The beginning of the end had arrived.
