Joyous Despair

WARNING: This one gets lewd. I won't be giving out similar warnings again, but if you were only here for the biological war crimes and purulent humour, this chapter is the point where the numerous signs that the MC is a horny bastard stop being hypothetical. Regardless, enjoy!

The boat took a few minutes to arrive, during which All Might called Endeavor and filled him in on exactly what needed to be done and that he was the best person for the job. He made several other calls after hanging up on the flame hero, likely to government officials who would undoubtedly manage to both downplay the danger and fly completely off the handle simultaneously; by the expression on his face as he held the phone slightly away from his head, these were not pleasant discussions.

In the time between All Might finishing his last call and the boat arriving, he finally decided to call me out on the most obvious flaw with my cover. "So what exactly was that scythe? It… reeked of malice and decay and I'd be hard pressed to label that thing any sort of beloved heirloom."

I sighed, "It actually is, to an extent. As you've probably guessed, my Quirk allows me to suppress and consume diseases." Here I locked eyes with the hero, lying through my teeth with absolute confidence. "My grandfather had rather the opposite, allowing him to control and enhance diseases. He created that blade during his time as a villain, forging it out of all his most horrid plagues compressed down to a solid state. He never made it big as a villain, mostly acting from the sidelines and selling bioweapons to the highest bidder." I ran a hand through my grimy hair, idly noting I could carry Izuku one handed with ease. "He went about this for a long time, before eventually finding himself caught in the midst of an attack using his own creations. He was immune, but his wife and children were not; after that, he found he no longer had the stomach for villainy and retired, but his blade was lost during the attack. He dedicated much of his life after that time to finding the lethal reminder of his misbegotten past, but all he found was the trail of destruction left in its wake. He finally found a lead that some small-time villain around here had gotten their hands on it, but they wound up dead shortly after with the blade nowhere to be found. He intended to make this trip himself, but suffered a stroke and died shortly before he could make the flight and I came here to finish what he could not." All complete lies made up on the spot, but said with the confidence of one with absolute conviction. "I'm truly sorry you and your daughter got caught up in this; I never intended for anyone to get hurt on my quest to put an end to my family's dark legacy." This story wouldn't hold up to intense scrutiny or any form of background check, but I didn't intend to stick around long enough for that to matter.

Always hit these types with the heroic quest and redemption lines, they tend to eat that shit right up; by the sympathetic light in Toshinori's eyes, he was no exception. He sighed, his gaze shifting to the girl in my arms who was already beginning to show signs of the great plague changing her. "I'll believe you, for now. Just tell me… can you really save her?" Considering he had yet to correct me on her being his daughter I was beginning to wonder if she actually was in this universe.

I looked down at the girl, watching her take in quick and shallow breaths; her skin was already going pale, lesions were forming all over her body, and looking closely I could already see her eyes beginning to move closer; though perhaps that last part was just my expectations working against me. "Maybe. I can't completely halt a sickness this potent, but I should be able to dull the pain and hopefully keep her alive by the time it runs its course." I turned back to the living legend, my face grim. "I warn you; even if she survives this, she will be forever altered in body and mind. You may not recognize her when she comes back, but if all goes as well as it can she should still be the same person despite the… trauma of what is to come." Mostly anyway; even if I could prevent her from losing her soul and twisting her mind, why would I want to stop her from becoming obsessively loyal to me? I'll try to keep as much of her personality intact as I can, but she will still be a Plaguebearer by the end of this.

He looked like he was going to say something at that, but the arrival of his yacht cut off any reply. All Might flagged the driver down, directing him to park the vessel nearby. The driver did as instructed, parking the large boat just off the cost before sprinting away at top speed; of course, it was already too late for him. While I had absorbed all of the Great Pox I could find in the area, I had not bothered to prevent the other diseases from spreading; in a few days, that driver would come down with something nasty and spend the rest of his short and miserable life vomiting his guts out. The only reason All Might wouldn't be suffering the same was because I had suppressed the sicknesses that had taken hold in him; he would still be a carrier and I could release them whenever I pleased, but he won't succumb anytime soon.

He should have known better than to get so close to a proto-Garden of Nurgle, but it was oh so kind of him to give me such a lovely arrow in my quiver for the future. Oh well, live and learn... or perhaps not.

I had to suppress a sinister chuckle at that with a force of will, letting the nerves in my face go dead to keep from smiling openly at the misfortune to soon befall the world's greatest hero. With all the nastiness he was carrying, it wouldn't be long before those he saved began falling ill sometime later. I could almost taste the sweet despair he'll feel when he realizes he was the one to doom the very people he meant to protect; his misery would be like a fine wine when the time came. He was a good man, and I truly liked him, but there was never any real chance we would be anything but enemies.

Putting aside my wicked plans for now, I waded through the garbage around the fetid pit Acceptance had created; I could feel the gelatinous rot squish between my toes in a way I knew would have driven me up the wall before I arrived here but now just mildly amused me. I tried my best to keep Izuku above the garbage as I made my way to the boat, holding her above my head as I walked.

The yacht was quite large, easily capable of hosting a party of dozens and with several bedrooms. As I approached the ladder, hooking Izuku's arms around my neck to keep her from falling (she still had enough strength to cling to me, if barely; a rather impressive feat considering her state), I turned my head to address All Might. "You'll need to burn this boat at sea when we get back… If we get back." I was halfway up the ladder when a thought struck me, "Oh, and I'd recommend you don't send anyone out to try and monitor us; I won't be able to protect them if they get too close."

I could hear him sigh even from a hundred feet away as I crested the top of the boat, "That isn't my choice young man, though I wish it were. I'll try to warn them, but I suspect at least the Coast Guard will be sent in some numbers."

I turned to face him with a grim expression, "I doubt any of them will make it home then; if they do, they'll only bring the sickness back here." I certainly wouldn't be putting in any effort to save them, even if I could.

Deciding to save exploring the boat for once I was already out, I simply found the master bedroom and deposited Izuku on the bed. She feebly clutched onto me as I attempted to walk away, mumbling feverishly. I stroked her head, gently unclasping her hands from my shirt, "Shhh, I need to get us away from the shore before the extremely contagious sickness pouring off you kills the whole world. I'll be back soon, and you won't even notice I was gone." After suppressing Nurgle's Rot for several minutes, setting the lesser plagues within her and All Might to display no symptoms even when I wasn't actively keeping them at bay was child's play; though, suppressing her pain from a distance was difficult enough to make for good practice.

She grumbled some more, but didn't offer further resistance. I sighed as I walked away from her to find the steering wheel for this damn boat; I had approximately zero faith in my ability to accurately steer a naval vessel, but I highly doubt I'll have any trouble getting us hopelessly lost at sea so long as I just picked a direction and kept going.

It was only as I was pulling away from the shore that I realized I had forgotten to ask for food and water, let alone enough to last for what may be over a week. It was also at that point that I realized I had accidentally consigned myself to spending my first week (or more) in this world caring for a sick protagonist while she slowly transformed into a daemon. I let my forehead rest against the steering wheel, lamenting my poor decisions of the last few hours before sighing and moving on; oh well, at least this will give me a relatively safe place to practice my new powers with minimal risk of accidentally releasing a super plague and exterminating all life. I was going to be killing a lot of people eventually, but accidentally killing everyone before I could make any use of this world or even get a proper grip on my powers would be highly irritating and a massive waste.

I waited for about an hour after I could no longer see the shore before simply walking away from the wheel and letting the boat drift where it may. I could hear Izuku screaming as I explored the ship, the might of Nurgle's greatest plague flaying her nerves even with her ability to feel pain almost completely suppressed. I made sure to be quick about my search, finding only enough supplies for a few days if rationed, a few useless knick knacks, and a radio.

I glared at the small kitchen and supply room for a moment, making a mental note to ensure whoever it was that stocked this place got to experience the full effects of the nastiest sickness I could personally devise for as long as I could extend their life. Still, knowing there was nothing I could do about our lacking resources, I simply shook my head and walked away; the ability to accept and move on was one of Nurgle's highest virtues afterall.

I set a chair beside Izuku's soon to be deathbed, holding her hand and muttering empty encouragement as the most dreadful sickness ever devised ran its course. I watched as she rotted alive, her skin sloughing off and regrowing over and over again, her bones shifting and breaking and weeping foul smelling offal, he innards swelling up and bursting out of her necrotized skin, her muscles turning black and leaking out of the innumerable lesions and weeping sores covering her body. Even with me there to guide her growth and preserve what I could of her mind, she spent most of her time sobbing and screaming as the spiritual disease ran its course. Three weeks she stayed like this, her incredible spiritual fortitude clashing with the unstoppable march of Nurgle's masterpiece and eventually being found wanting.

Occasionally, I would have to leave her side to get her food or water. When we ran out of food after only three days, I released a slow spreading and fast killing disease into the water and watched dead fish rise to the surface; it was crudely made in a kitchen cauldron, but so intensely lethal that it would kill the hosts before they could spread it very far. Nurgle would probably disapprove of such a piss poor first foray into plague alchemy, but I wasn't trying to make anything actually viable just yet. The fish were obviously diseased and probably slightly rotten by the time I cooked them up and served them, but given what was already running through her system it hardly mattered.

It was nearly a week before the boats I knew would be sent arrived; five little gunboats that encircled our ship at a distance of about fifty yards. They contacted me on the radio, making sure I was who they were looking for; I warned them to pull back further for their own safety, and they informed me they were confident in their precautions and politely told me to go fuck myself.

The screams started a day later, and by the time Izuku's eyes had melted into one the ships had gone silent. Seabirds circled overhead, but those that dared to land on any of the increasingly rotten boats around us never flew again. A week after the ships arrived, a cheerful, gurgling voice contacted me on the radio, "Oh blessed lord of wondrous decay, how may we be of assistance?" Evidently, they had much weaker wills than Izuku to turn so quickly.

I gave a grim chuckle, hoping whatever means by which I was being monitored didn't catch or care about that message as I turned off the radio. Knowing I couldn't risk actually ordering around my new pack of daemons over an unsecured line, I drew upon my connection to the nearly silent Warp and the connection I could feel with the feculent foot soldiers in an attempt to communicate psychically, "Strip the ships of weaponry, set the ships on fire, then simply rest within the Warp until I call upon you.'' It took a moment, but I could feel them respond to my commands shortly after I called out; from the grimy window in the thoroughly ruined captain's cabin, I watched the tall embodiments of sickness happily strip the mounted machine guns from the prow of each boat and methodically search the structure. Once they were sure they had collected anything that could reasonably be called a weapon, I watched them vomit up a thick and oily substance and toss flares into it, igniting the small ships in a grand blaze of sickly green flame that belched thick and putrid looking smoke. The daemons each gave me a thumbs up before using their Plagueswords to cut holes into the sea of souls and carrying their spoils away.

My psykery certainly needed work, but the knowledge I could apparently command the loyalty of daemons was certainly pleasant; unsurprising given the lack of any higher authority in this Warp, but still nice to know.

By this point, Izuku had moved on from screaming and crying and started to laugh. She was a hulking thing at this point, clearly destined to be a Poxbringer of notable strength from the crown of horns poking out through her bile and rot streaked hair, the visible aura of sickness and thick cloud of flies wafting off of her only further proof. Her single emerald eye finally had enough lucidity to actually observe her surroundings (mostly just following me at a languid pace), but it would still be another few days before she finished her transformation completely. I murmured encouraging words and stroked her hair as she took slow, shallow breaths; while I'm uncertain she was able to understand me at all, she seemed to take some comfort from the actions regardless.

In the final days of her transformation, as the disease began to settle down and her broken and twisted soul took its final form, I found much greater ease in controlling her appearance. The boils and blisters faded, her burst open guts sealed up, and the numerous open sores closed; by the time she had fully transformed into a Poxbringer, she could almost pass for a more normal mutant if not for the cloud of flies and coating of putrid slime.

I smiled at her as she slowly gained her bearings, her new and impressive nine foot height (and additional two-ish feet of horns) throwing her off balance. She slowly looked over herself, her single eye taking in her slimy green skin, gangly limbs, and noticeable swollen breasts and rear. Her vagina was mostly intact as well, save for her flesh turning green and her fluids being noticeably yellowed; though, based on the few seconds she spent touching herself I could tell she retained her capacity to feel pleasure at least. She seemed slightly dismayed by the fact that her stomach had noticeably swollen up alongside her already massive chest, but by the time she finished her self exploration and turned her gaze upon me she seemed content.

Plus 100 Affection from Izuku Midoriya for owning her soul, Affection locked.

Plus 100 Obedience from Izuku Midoriya for owning her soul, Obedience locked.

She smiled as she looked at me, the devotion in her eye almost frightening. She sank to one knee, coming eye to eye with me despite the submissive stance. Before I could say anything, she put her hands on my shoulders, pulled me forward, and buried her long tongue down my throat. I'm sure her saliva would taste foul to a mortal man, but I was physically incapable of being disgusted anymore and the feeling of her sinewy muscle writhing about inside my mouth and throat was nothing but pleasant.

By the time she pulled back I was beginning to notice I didn't seem to suffer over much from lack of oxygen, but I allowed that observation to be drowned out by pleasure. She panted, severing the string of yellow saliva that connected us as a wide and toothy grin spread across her face, "I am going to fuck the shit out of you, milord." Apparently the Plaguefather's embrace had upped her confidence significantly, though I had little time to contemplate this before I was physically thrown onto the same bed she had spent the better part of a month turning into a daemon.

I knew this was a bad idea, I knew All Might was probably watching and that this would be exactly the sort of thing he was not going to be happy about… but as I watched her crawl over me, her massive breast so large her mint green nipples trailed over my skin even with her arms fully extended, I couldn't bring myself to care. I smiled at her as she pulled down my pants, revealing a cock that could only have been a blessing from Slaanesh and eagerly wrapped her feverishly warm tongue around it.

The feeling was like nothing I'd felt before, both from the sheer length and warmth of her tongue as it wrapped all the way around my dick several times and from the strange consistency of her saliva; it was notably thicker and stickier than a mortal's drool, making her writhing organ tug pleasantly at my sensitive skin. I sent a quick prayer to Nurgle and Slaanesh as she pulled me fully into her furnace hot mouth, thanking them in the most extravagant terms I could manage for not taking away my ability to feel pleasure along with the pain.

Her throat writhed around my turgid tool as she put her total lack of a gag reflex to use, drawing moans from me as I stroked her hair. "That's it girl, just like that…" She hummed happily at my praise, and the vibrations it sent through her throat pushed me over the edge. She eagerly milked me as I came, pulsating her throat and humming some sort of hymn as I pumped shot after shot of cum down her throat. Eventually I came down from my peak, and she slowly pulled off of my cock, giving it a final lick as she pulled away.

Normally, I would find myself growing soft for a few minutes after orgasming like that, but being a scion of the father of flesh had some unexpected side benefits; namely, I could control my biology much, much better than most. In other words, If I didn't want to go soft I simply wouldn't, and I never get tired. Seeing I was still ready to go, Izuku gave a happy giggle and crawled over my chest to line up her dripping wet cunt.

Her huge breasts smothered my face as she wiggled over me and I took the opportunity to suck on one of her protruding nipples, drawing a pleased gasp from the now much larger girl. I was surprised to find that she actually started producing sweet tasting milk after I started suckling, but I didn't have long to appreciate the strange but pleasant taste for long before she pulled away. I met her single eye as she held herself aloft just above the tip of my cock, her fang filled maw pulled into a lusty grin the likes of which had likely been never seen on a creature like her, before she let herself drop.

I almost came again the moment her blazing hot pussy enveloped me, her virginal tightness around my sensitive member enough that I'm sure it would have been agonizing were I still able to feel pain. Instead, by the grace of the All Father, I felt nothing but pleasure as she slammed down on me. She howled at the penetration, the sound like a dying moose as she roared her pleasure to the heavens; she didn't linger for long though, the blessings of Papa Nurgle taking away all pain, enabling her to ignore any discomfort she may have felt at losing her virginity and begin humping me right away.

Her slick passage somehow managed to feel even better than her throat as it writhed around me, the walls of her pussy seeming to ripple around my cock as she roughly slammed herself against my crotch. I was once more thankful neither of us could feel pain, else her roughly impaling herself upon me over and over again would have certainly been less than pleasant; as it was however, my only thought outside of how good she felt was that I wished my arms were long enough to reach her bouncing breasts from where I lay.

It wasn't long before she came, another scream of joy ripping through her throat as she shuddered atop me. I was almost worried she was going to stop there when she leaned forward to rest her body atop me as she convulsed around me, but she barely paused a moment before resuming her prior pace. With her now leaning over me rather than away, I was able to wrap my fingers around her enormous breasts and happily took the opportunity to maul them for all they were worth.

The next time Izuku came, she powered through it and just kept on riding me even as she convulsed around me; the sensation of her twitching wet walls sliding up and down my dick was more than enough to push me over the edge. With a roar of pleasure to match her own, I drove myself up into her and released my seed within her daemonic womb.

I slowly came down from my orgasmic high, panting and idly squeezing her tits as I lay back. She all but collapsed atop me, pressing her warm flesh over my entire body as she came down from her own high. I smiled into her soft and yielding flesh, contemplating going again…

-100 Affection with Toshinori Yagi for fucking and brainwashing his surrogate daughter.

Until the sound of distant sirens and one very unwelcome message in my brain knocked me right out of my good mood. 'Fuck fuck fuckfuckfuckfuck, I knew that bastard would be spying on me!' I ranted inside my head, calling the hero every expletive I could imagine as I pushed my newfound lover off of me. She didn't seem bothered with my abrupt treatment, only sending me a concerned look as I hastily jumped out of bed and began pulling my pants up. I met her gaze, "All Might's got this place rigged up with some sort of surveillance, while I'm sure the rot seeping in will have dealt with most of it, enough of it must have been intact for him to tell what we just did and I'm guessing those sirens mean he is not happy." I spoke quickly, pulling my shirt over my head as I began to run towards the door. "Whether that's because I slept with you or because he thinks I'm responsible for this whole plague thing and the deaths of those Coast Guards, I don't know or care, but I have no interest in spending the rest of my days in a biohazard cell regardless." Not that such a thing would be able to hold me for long, but it's the principle of the matter really.

I threw open the cabin door, gesturing for her to follow as I ran out onto the mouldering deck. She followed close behind me, only running into a few issues keeping up when she kept banging her horns on door frames. I sprinted to the edge of the ship, seeing a number of heavily armed boats on the horizon. I grimaced at the sight, though the angry buzzing of innumerable flies that could not possibly have arrived here by any natural means drew my gaze back to my companion. The kind hearted girl had a vicious scowl on her face, her sheer anger having drawn this swarm of vile insects to her through the very Warp and seemingly enabled her to unconsciously summon a massive Balesword to her hand.

I grabbed her long hair, pulling her down to eye level with me. I knew I couldn't say what I needed to aloud lest All Might or the authorities in general hear me, so I focused on my newfound Psykery and projected my thoughts into her mind as best I could, "I'm going to flee. You can either come with me and become a villain, or stay here and tell them that I used my control over disease to force you to love me until you managed to break free while I was distracted. If you stay, they will likely put you into an ineffective quarantine for sometime, probably long after you manage to get a handle on your powers and stop infecting everyone around you by accident; however, this will be the only chance you have to maybe remain All Might's successor and a hero. If you come with me, you'll never have another shot at anything but villainy."

As much as I wanted her at my side, I wanted her to get One For All even more. The odds were slim to be honest, but if things ever got too bad for her she could simply flee into the warp; besides, it's not like they could actually successfully torture her even if they were willing to try it. Worst comes to worst, I'll gas whatever prison they send her to and bust her out with a daemon army; there is no fortress on this Earth that could keep a legion of Plaguebearers out for long.

She looked conflicted, staring into my eyes indecisively for a long moment before slowly nodding. "I can tell you want me to get his Quirk. For you My Lord, I will try."

I pulled her to me, slamming a kiss on her lips before pushing her away. "If a Detective Naomasa attempts to interrogate you, silently release a fast acting and extremely lethal disease into the room to kill him. He, and I think his sister, have the ability to discern truth and lies, though I don't know if it will work on a daemon; either way, killing him quickly and making it look like an accident is your best bet. Now dodge, we need to make this look real!" I made a show of summoning Acceptance to my hand and sending a telegraphed and easily dodged strike at Izuku, shouting "You fucking traitorous whore!" at the top of my lungs.

She leapt back just slightly too slow, allowing the blade to carve a shallow line across her bloated stomach. She cried out, dropping her Balesword and pretending the shallow wound actually caused her any pain as she fell onto the deck. I stood over her, scythe raised high over my head as if I were going to finish her off before a bullet impacted my shoulder and sent a spray of my festering blood into my face.

I gave a loud and angry roar, turning to blow a thick green cloud of pestilence over the water at the impudent fucker that had the gall to take a shot at me. The cloud of disease rolled across the sea and engulfed the lead boat, rusting the metal on contact and causing painful boils to spread across the crew; it wasn't long before they began choking and desperately clawing at their necks and chests as thick pustules filled their lungs and throat. In seconds the men were laying on the deck, pus from ruptured boils leaking out of their mouths and noses as they died in agony.

I didn't bother watching the men die, instead turning and sprinting across the deck of the ship, letting my power run rampant as I did. The ship rotted rapidly beneath me, boards blackening and fungus rising from every crack as insects seemingly crawled up from nowhere. By the time I reached the other railing, it was already rusted so badly it offered almost no resistance when I slammed straight through it.

I couldn't help but grin as I plummeted into the cold water below; it felt damn good to let loose after restraining myself for so long. I knew I'd probably regret this later, but in the moment I was thrilled!
