Kurotsuchi Week 2026 - Day 1 : Birthday / Mayuri's childhood.

Happy birthday to the Kurotsuchis <3

Mayuri is definitely at least in the triple digits of his age, and Nemu must be under 100. I love this family.

The whole division is actually celebrating. Mayuri just wants the cake and for everyone to go back to work.

Kurotsuchi Week 2026 Day 2) 31.3. - Young man before Maggot's Nest / Maggot's Nest

any excuse to draw more of shin'o academy mayuri 😌

--

"What is this?"

Urahara makes an inquisitive sound at the sudden question.

"You know just as well as anyone that zanjutsu is my worst subject", Mayuri continues. "So why drag me out here to spar? Just to humiliate me?"

Mayuri's distrustfulness shouldn't surprise Urahara anymore, and yet he can't help but chuckle at what seems like a frankly ridiculous question from where he's standing - or lying, as it were.

"I don't think it's you who has to worry about being humiliated", he says, sitting up.

"Do you think I'm stupid? You're losing on purpose, and I want to know why."

Urahara smiles and shrugs. No, Mayuri Kurotsuchi might be many things, but stupid is certainly not even close to being one of them. "Maybe I just wanted to see you all sweaty and disheveled."

The scoff Mayuri lets out is possibly the most frustrated and annoyed Urahara has ever heard him, which is saying something. He turns around and starts walking away, helping Urahara up clearly not something that even crossed his mind. Urahara jumps up, grabs his bokken from the ground and jogs up to walk alongside him.

"You are a perplexing and irritating man, Kisuke Urahara", Mayuri mutters without a hint of fondness, not gracing Urahara with as much as a glance.

"Come now, Mayuri-san, you know you don't have to use my full name everytime."

"That's 'Kurotsuchi' to you."

KUROTSUCHI WEEK DAY 3

Failed experiment/ what's this goo?

[Yes I do realise my drawings this week seem to have nothing to do with the prompts, bear with me]

HOW DARE YOU

Summary: something goes wrong in Mayuri's lab... to escape death, he stabs himself with Ashogi Jizo and turns into slime. But life as goo ain't easy, my friend.

Mayuri Kurotsuchi x Zaraki Kenpachi

Wc: 600

Tw: supposed to be funny but who knows anymore, I'm too tired to tell. Mayuri is slime. Zaraki finds it hilarious.

Link to Ao3

The first time it happened, Zaraki almost had a heart attack.

He woke up at the crack of dawn covered in a suspicious green substance that made his skin tingle, and the scream he screamed could be heard all the way to the Soul King's Palace and back.

He rushed to his bath and scrubbed vigorously until his skin was red raw, and it wasn't until the last of the viscous goo was already spiraling around the drain that he heard a distorted voice, crying for help... he wasn't too sure he hadn't imagined it, perhaps he was hallucinating, but it reminded him very much of a certain scientist he knew very well.

The following morning, said scientist spent two hours screaming "how dare you!" at him for mistreating him and making him traverse the disgusting pipes of the 11th.

"The things I saw down there..." Mayuri shouted, grimacing with utter disgust "the stuff of nightmares, Zaraki. Nightmares!!"

For a man like Mayuri to say that... it had to be pretty rough down there.

Zaraki had let him rant until he ran out of steam, and somehow kept a straight face the whole time, despite how hilarious he found the whole ordeal.

It seemed that one of Mayuri's experiments had gone awry and caused an explosion the man hadn't anticipated. His injuries were grievous and therefore, he had decided to stab himself with Ashogi Jizo instead of attempting kido healing.

But, without Nemu's help, and since Akon was away on a mission, he didn't have anyone to assist him during the process.

Hence, he'd decided to find Zaraki. But travelling as green goo through the Sereitei wasn't easy task. He'd been stepped on, stared at with disgust, cursed at, and a drunk lowly officer even tried to piss on him! Of course Mayuri made sure to remember all of their faces to retaliate later.

In the end he was exhausted and frozen to the bone... well, let's say to the core. He was frozen to his gooey core, yes, and, looking for warmth, he had spread himself in a thin layer over the man who once swore to love him no matter what. Apparently, his love did have limits, gooey limits. Zaraki hadn't given him a second to react before he'd started to peel him off his skin, sucking him into his germ infested sponge and basically water boarding him until he almost drowned.

He'd tried to scream but all he'd managed was an unintelligible gurgle. And well, after that he'd been dragged through the muckiest muck. The sewer system of the gotei was old, and at one point all pipes mixed into one. Whether they came from shower, sink or toilet...

In order to avoid vomiting all over himself and relieve his trauma, Mayuri decided he'd screamed enough.

That had been a long time ago.

Now, when Zaraki woke up in the middle of the night coated in a viscous sheet of his favourite scientist, he didn't panic. He smirked and sunk his fingers into it, swirling the green slime in circular motions until it started to purr, and waited till the morning. In most cases, by then he had a mostly solid, blue-haired man sleeping on his chest. And if he was lucky, an awake one, snickering to himself as he began a slow trail of burning kisses from Zaraki's neck to below his waist.

Kurotsuchi Week Day 4: working for Urahara/TBTP

This was originally gonna be a series that showed this same 12th division office (an office I completely made up but am sure exists in some form) throughout the years, starting here and ending where Kubo left off with beetle Mayuri/Hell arc. But then I realized that's a fuckton of work🙄 and the project got canned lol. Anywayyyyy look at these absolute goobers, i love them sm

Thank you @toxictaicho and everyone else who put together this event, feels good to do something other than my own macabre ideas for once:3

some more rambling about the art under the cut

Fun Facts: I was gonna do a simple, regs looking window to show how the 12th as we know it is just starting out, a pre 'stained glass thistle window' like in my other arts* but the prospect of doing a less colorful office was borrinnnngggg as hell😭 so stained glass it is. Also Mayuri and Hiyori are supposed to be antagonizing each other, but I kinda like how it could also be read as both of them glaring at Urahara, who's doing his best 'just a normal guy' impression Also kudos if you notice the reference to a certain book/movie, which is in itself a reference to Kisuke's character in my fic Imperfect (he evil lol). There's a few more vague references to that character scattered around, like so vague they might just be unvoiced hcs tbhhhh... either way, most of it is just random clutter

*other arts are here (x) and shown below since I never actually posted it outside of a group??? i searched for fucking AGES before i rememebered that. In case you've never seen it, this was my submission for the Madness and Malice zine back in '23. At the time, I wasn't a big fan of how it turned out, probably why I never posted it (Nowadays I don't think it's bad or anything, was just a learning experience)

Kurotsuchi Week Day 4 - TBTP working for Urahara

Look, we know how well Mayuri gets along with Urahara, I bet he would sometimes attempt to menace him with creatures only for it to fail for various reasons. Hell, in this alone I can imagine Hiyori walking in and just yelling at Mayuri, and then Urahara for not paying attention. Only for Urahara to reveal that he was aware, pissing both Mayuri and Hiyori off for two very different reasons.

Pink Fish

Mayuri x reader

tw: Noncon/dark

Warning: abduction, medical experimentation, noncon, dark, creepy, death mentioned

Day 3:

What’s this goo?

Squirming in bed, you wonder the same.

It's sticking to your legs like a glob of industrial radiohazardous ooze. It seems to be odorless, however, it is heavy and tacky. Whatever it is, it is certainly giving you the ick.

Rubbing your thighs together seem to make it worse and more oozes out between your folds/hole. You lay there naked with nothing but a memory of a man who abducted you in your dreams.

But the goo clinging between your thighs suggests it wasn't a dream.

You finally toss to your other side, back sore and achy, like you just banged into a wall. As you move from side to side, more goo trickles down your inner thighs.

Eyes flutter open, getting used to the new adjustment, and you let out an audible gasp when you are greeted by the creator of the mess.

It is dark, so you don't see much. Just his painted face and a wide spread grin, his face illuminated by the glow of his laptop. He makes himself comfortable next to your bed, leaning forward on your chair and closely monitoring your icky body. You realize this isn't your bedroom when you spot the giant fish tank behind him filled with big pink fish.

You try to open your mouth again but appear paralyzed with fear.

“It's not fear,” he replies to your unspoken worries.

You refuse to believe that it is more than just fear.

The coldness spreads from beneath your core- down your legs and up towards your neck. The heaviness continues to grow, panic setting in and taking a ride with your nerves.

“Relax. All will stop making sense soon enough,” he makes no effort to lower your heart rate, which he closely monitors.

You lay in bed, unavoidably facing him, even your eyelids lose control. You stare right at him, fighting to close off your lids, however, an invisible force protests and pry them open. You have no choice but to stare at his soul.

This man has appeared in your dreams several times before.

A dream?

Yes! It is a dream! A nightmare!

You came from work and took a shower and went straight to bed.

But you never made it to your bed.

“A dream? What an insult to my creation”, he huffs.

You feel the tug of a wire and that is when you realize, your forehead and half-shaven head is connected to electrodes and wires.

You can't open your mouth but you know your vocals are not paralyzed just yet. You manage to create a rumble of a grunt which surprises the man.

“Oh! Still got some strength in you? You certainly are a fighter of a specimen for someone who is half dead. You humans love to play with death. Installing a slippery mat inside an already slippery bathtub happened to work in my favor. Now stop with the struggles. It took many stitches to patch up the gash in your head. Really nailed that tap right inside your brain.”

You let out another groan. Bits and pieces of memories came to you. You really did fall in the bathtub and hit your head against the faucet.

So you were dead?

Or, like he put it, half dead?

“Both”, he replies.

You don't feel the sticky goo pooling between your legs anymore. Your body has become completely numb. Suddenly, you miss that sticky sensation and dread the next phase of your soul's journey.

“A soul? Don't be absurd. I saved your wretched body from becoming a complete soul”, he explains. “You will become a temporary container for one of them.”

You don't understand him.

“I don't need to explain anything to anyone. Be grateful I picked up your rotting body from the gates of death. Now rest up, we have a big surgery ahead.”

Surgery? It all becomes clear when you notice a large, ceiling height cylindrical glass container behind him, with a bunch of floating brains.

Oh, you wish they were pink fish. Pink fish are much prettier.

“Now which brain should I fish out for you?”

Happy Birthday

Mayuri x Reader (minors dni)

Tags: usage of pet for reader and master for Mayuri, and a reader that doesn't go over the top for birthdays. This is (hopefully) cute and I hope y'all enjoy it! Also - I personally headcanon Mayuri as partially deaf or hard of hearing, and headcanon that his childhood was not great. So that's in here too.

Mayuri never made a big deal out of his birthdays. And he had told you as much, after you had been together for some time. What was another year to a shinigami like him anyway? It wasn't like his birthdays had meant much as a child. Born hard of hearing, sickly, a curse. Abandoned as a babe. As a man, he didn't need his birthday celebrated. Very few people knew when his birthday was to begin with.

You were one of the few. He trusted you with that information and when you had said you were going to stay home and 'work around the house' that morning, he knew. Mayuri wasn't stupid. And you knew he knew. You were up to something and he was sure he'd find out when he returned from the lab.

Mayuri walked into his home, rubbing his temples. He followed his routine without seeking you out - showering off the day, the paint, and dressing in a comfortable yukata when he was finished. Switched the large cones he wore over his ear ports for smaller ones, which he only did when off duty.

He padded to the kitchen, where he figured you would be. He was correct.

You were putting dinner on the table, looking perfectly content and pleased with yourself. On the table was one thing - a simple card.

Mayuri was almost immediately suspicious. He narrowed his eyes. "What is this?"

You glanced his way, smiling warmly. "Dinner, master Mayuri. What does it look like?"

He snorted softly, eyes darting around the kitchen. "Just dinner, yes?"

"There's one special thing you'll get after dinner. But that's all." You answered, watching him.

"And the card?" Mayuri muttered back.

A sigh passed your lips. "I know how you feel about your birthday. I know you don't want a big deal made out of it."

"Correct." Mayuri's eyes were locked on your face.

"It's the only thing I got you. Just from me." Humor tinged your voice. "Did you think I'd try to throw you a surprise party? With streamers and candles and guests?"

He wrinkled his nose. The thought nearly made him shudder. "I would certainly hope you'd know better than that. I'd make garden decorations out of the 'guests'."

You laughed softly. "Come and eat, master Mayuri. Please?"

Mayuri padded to the table and sat, with you sitting across from him. He looked over the food - several of his favorites, included pike fish, and blessedly you'd remembered he hated onions.

The two of you ate in relative silence, the kind of comfortable silence Mayuri appreciated about your presence. You were kinder to him than any soul he'd ever let close. Quick to smile, quick to dote on him when he needed it, quiet and intelligent in your way, so good at reading him that the first time you'd done it he nearly processed it as a threat before realizing you were being nice. And now you were in his house, cooking him a birthday dinner. He had been suspicious for no reason.

When the two of you were finished, you cleared the table and went to the fridge.

"This is the real present." You said proudly while your back was turned.

Mayuri tipped his head. "Well? What is it?"

You turned, and on the pretty serving dish in your hands sat a strawberry cake roll. The icing dotting the top was a bit uneven, but you were proud of it anyway.

Mayuri blinked. His favorite dessert. And you'd made it yourself. A grin made the corners of his mouth quirk up.

You brought the cake to the table and placed it in the center. Leaning down, you pressed a kiss to the side of Mayuri's head.

"Happy birthday, master Mayuri."

And it was. The happiest he'd ever had.
