Notes: Okay, here's how this is going to work. once Unrest and switch reach chapter 15, I'm going to update them and Heartsbond five chapters at a time. 5 HB, 5 Unrest, 5 Switch, in that order.

Zephly was angry, very, very angry. Marvin the martian "you make me so angry" angry. Kill something for the sake of killing it angry. "THEY WHAAAAAAATTTTT?"

"They're gone." Kamrin replied. "They defected to the shinigami and fled."

"So the shinigami are interested in stealing my research hmmm? Well, I'm about ready to give them more of my research than they can handle. Tell Aizen I've finished the second strain of the reproduction virus. And very soon I'll have the emergency response time of their defenses of Karakura. Get Foarmin and Cheiz down here. We're going on a raid."

The alarm went off in the twelfth division. "Espada! Its an Espada!" Rin ran for Akon, who sounded the alarm.

Instantly Yumichika, Ikkaku, and Rangiku dropped what they were doing in the human world and ran for the location specified.

Hitsugaya had been half asleep in Shinji's arms when his soul pager went off. "Espada! In the human world? SHINJI GET UP! We have to go!"

Shinji yawned and stretched. "Alright alright I'm coming. We can't fight them on our own. Want me to grab some of my friends? Kensei's pretty strong."

"Rangiku, Ikkaku and Yumichika are stationed in the human world in the event of an arrancar attack. They'll be already enroute to the location. It seems they've attacked in the park."

Shinji and Hitsugaya dressed hurriedly and flew to the spot. Along the way, Rangiku flanked him. Then Ikkaku and Yumichika surged up from below. "Hitsugaya-taichou, who's your tag along?"

"Shinji Hirako, one of the vizard and formerly captain of division five." Hitsugaya said tersely.

"Aizen was my lieutenant." Shinji told the shinigami. "He entrapped me and the other vizards and attacked us in order to get our posts. Most of the current captains and lieutenants have Aizen's upheaval to thank for their jackets." Shinji added.

"Shinji is going to be teaching me basic information about the vizards. They've discovered a lot about their people since they were exiled."

"We've discovered how to stablize our transformations." Shinji explained. "Rather than creating rampaging monsters."

An explosion sounded over the horizon, "That flame... SHIELD YOUR EYES!" Hitsugaya warned.

The explosion's flame was violet hot, blindingly bright. Zephly looked up amongst the flames. Next to him were three arrancar in their ressurecion forms.

Zephly was riding on the back of a three headed dog hollow. The dog hollow looked up, howling a challenge from all three heads. Zephly grinned stupidly, flipping the bird at hitsugaya.

Hitsugaya only paused to look at the three released arrancar, the female's released form resembled a Roman centurion with a pair of elegant, spiny bone wings that extended from her back. Instead of a roman short sword she had in her hand a pilum made from glowing pale blue cero.

The first of the males has a helmet shaped like the head of a jackel. His hands and feet were dog like, almost like a werewolve's. He carried the armaments of a greek Peltast. (1) His hair was platinum blonde, like Hitsugaya's, eyes golden in keeping with the dog theme.

The second of the males was dark skinned, but he had pale blue eyes, rather striking. He was wearing the armor of a Roman Murmillo Gladiator with the face plate up. (2)

Zephly looked up at Hitsugaya, their eyes met. The three arrancar looked up and raised their zanpakuto, cero forming at the tips of their weapons. Not just any cero, gold, with a faint hint of violet to them. "Look out!" A firing squad of ceros shot at the incoming shinigami. They couldn't even get to the ground. Rangiku was hit square in the stomach by one of them, dropping like a stone.

Then Hitsugaya looked down at Zephly, eager to try and attack him. Only Zephly was gone.

Then a shadow appeared behind him. "Classic misdirection, Taichou-kun." Hitsugaya felt something nasty and sharp stick in the back of his neck. A needle? What did he want to stick him with a needle for?

Then Zephly was saying to the shinigami. "Hope you liked my special attack, Cero extincion. Extinction Cero. It recreates a miniature version of the blast that killed the dinosaurs. And you're about to experience not just extinction, but one of the four horsemen of the apocalypse as well." And he quoted a text that the shinigami rarely heard, being creatures of Japanese culture rather than christian. "I looked and there before me was a pale horse! Its rider was named Death, and Hell was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague."

Yumichika swung his shikai, having released it sometime in the chaos, at Zephly, only to find a knee shoved into his gut. Then Zephly shoved another needle into Yumichika's neck.

All of a sudden the barrage of ceros stopped. A garganta opened on the ground, and the three arrancar were gone. Zephly was standing in the garganta, waving over his shoulder as Hitsugaya dropped to the ground like a stone. "Taichou-kun, give Yamamoto my regards. And tell him to go fuck himself. He'll know what for."

The garganta closed behind Zephly, and Hitsugaya groaned. The injection site was burning like hell. "SHINJI!" Hitsugaya's vision was swimming, and he could barely pull out and dial his soul pager.

"Mayday, mayday....... Soul society... this is... Captain Hitsugaya... Zephly Ophiucus Ascepilas... has been sighted in Karakura... park... I've been injected with something.... its burning real bad... I can't see straight..." His distress call was broken. "We need a fire........ control....... unit....... the park is..... burning......" Hitsugaya collapsed, pain ripping through his lower body.

When the rescue party from the soul society arrived, and twelfth divisioners and kido corps members began to fight the fire, Unohana found Hitsugaya and Yumichika heavily feverish, bent over into a fetal position. Rangiku was severely burned. Shinji was favoring his right arm, having gotten a glancing blow. And Ikkaku's clothes had half been burned off him, though the third seat had been saved from severe burns by his souryoku.

Hitsugaya and Yumichika were taken back to the fourth, where Unohana examined them. When she removed their clothes, Hitsugaya and Yumichika's abdomens were black and blue and swollen. Their fevers were high.

Unohana administered an emergency fever reducer, took blood samples (which she sent to Kurotsuchi) and began to palpate the black and blue area with a glowing hand. Everything inside felt screwed up. It was almost like a controlled hemmoragic fever. She didn't like the looks of it in the least, hemmoragic fever was one of the most feared diseases in existence. Unohana had had to flee from an area of Africa she'd been studying herbalism in when the first few ebolla cases appeared, decades before. She'd narrowly missed being affected by the calamity and ever since then it was one of the diseases that kept her up at night. Zephly was thousands of years old, he had access to eons of knowledge of germs and disease and how they were spread.

Kurotsuchi called about ten minutes after she made this discovery. "Its the same virus as Ichigo. But its different this time. There's some minute differences in the genetic structure. It will take me a couple of weeks to decipher it. I need a scan of their bodies."

Both captains were concerned enough that they dispensed with the normal sneered pleasantries and veiled threats they normally exchanged when forced to work together.

"So do I."

"Unohana, their viral load is through the roof."

Unohana was scrambling with the body scanner, hands shaking. The image of Hitsugaya's lower body was displayed on a screen in front of her and in the twelfth where Kurotsuchi was trying to decode the virus.

Unohana gasped. It was like a bomb had gone off, any non vital organ in his abdominal cavity was being destroyed. Torn apart by the virus down to the reishi that made his organs. But Unohana saw also, almost immediately that new tissue was being destroyed it was being reformed into a modified female reproductive system.

"Damn." Unohana's face paled as she checked Yumichika and found the same changes being made. "This isn't good. Kurotsuchi please call Captain Yamamoto down here."

It took another ten minutes to explain what had happened to Yamamoto. Yamamoto had been debriefing Shinji, and had realized that the reasons for the attack were simple. Analyze the seireitei's emergency response time, and test the revised version of the Fever Virus.

Shinji sat by Hitsugaya's side, and Ikkaku trudged into the room in a fresh uniform. And slowly, slowly over the next few hours the angry bruises on Hitsugaya's abdomen disappeared. Hitsugaya groaned. His eyes opened. "Shinji?"

"hey Toushiro..."

"oh thats right, you can call me that now can't you?"

"If you want to make that more of a regular thing, then yes... would you like to? Yamamoto has asked me to give a series of special lectures at the shinigami academy. So we'll have some time to spend together."

"I'm glad. Right now I feel like hell. Frisky, but exhausted."

"Thats the bad news. Zephly stabbed you and Yumichika with syringes full of The Fever Virus."

"Oh nooooooooooooooooooooo..." Hitsugaya groaned. He had just barely started to confront what that bastard Gin had done to him, the littlest captain highly valued his self control.

Shinji hugged him tightly. "Yeah, its a fast acting strain rather than the one Ichigo got too. Looks like Zephly modified it. Evolving his technique."

"Aw crap, how long do I have before I'm humping someone's leg for baby juices?" Hitsugaya groaned.

"A day at most, but you're forgetting, you can hump my leg if you want. Unohana thinks the hormonal overload from the fever and childbearing could kickstart your growth. Though she wants you to start taking calcium supplements so the growth doesn't weaken your bones. You could be a handspan taller by the time we're done."

"But... I'd get /pregnant/."

"dude, my life is screwed up as it is. If you decide you want to get an abortion or put it up for adoption, doesn't matter to me. I'd like to be a dad but we're just getting to know each other."

"you actually want to try a relationship?"

"Because I know that that fever isn't you. Besides, I can turn it into a week of sexual healing..." Shinji purred.

"Shinji." Ukitake poked his head in. "I spoke with Unohana, you can borrow my little teahouse on the lake if you like."

"Thank you Ukitake-taichou, you're as helpful as always." Shinji chuckled. "Come on Hitsugaya, I'll rock your world." He reached out for the diminutive captain to hug him.

"Toushiro, please, call me Toushiro." Hitsugaya took Shinji's outstretched grip, wrapping his arms around Shinji.

Yumichika had his own private hospital room by now, and woke up to find Ikkaku asleep by his bedside, a bottle of sake abandoned on the bedside. But he woke soon after Yumichika did. "you look like hell."

"So do you. Remember how you complained you wanted a baby when Grimmjow showed up pregnant?"

"Yeah."

"You might get your chance. That damned arrancar injected you with the same virus Ichigo caught knocking Grimmjow up. Only it moves faster."

"oh?"

"yeah, it made all the modifications to your body inside of one day." Ikkaku leaned down to kiss Yumichika on the lips delicately. "Should be some time tomorrow morning that the Fever takes hold."

"So what are we going to do until then?"

"I got permission from Yamamoto-sama and Zaraki-taichou to go to that little cabin outside the West rukon. You know the one I'm talking about right?"

"yes, the place where we first had sex. I remember it all too well."

"So what do you say? Even if we walk, we'll be there by about ten pm tonight and have plenty of rest before you go all sex crazed." Ikkaku bent over Yumichika, continuing to kiss his koibito. "Which, by the way, will be very, very hot."

"You think I'm sexy that way?"

"I have no doubt that you will be. You're a very sexy person Yumichika." Ikkaku purred, rubbing their noses together endearingly.

"Thank you." Yumichika sat up, stretching. "lets get moving then."

"Isane will be coming to check on us in about a week, we have until then." Ikkaku grabbed one of the backpacks he had hidden underneath the bed and handed it to Yumichika. Yumichika changed into a fresh uniform, slipped the bag on his back, and the two lovers slipped out for a romantic hideaway.

"So I have till tomorrow morning?" Hitsugaya was still trembling, clinging to Shinji, who had sat down on the hospital bed next to him.

"Yes, as far as I can tell the virus is migrating to your hormonal glands. When that happens they'll self destruct. Its reading you as an uke due to physical build and body mass, so you will be unable to pass it to whomever you are sleeping with."

Hitsugaya snuggled against shinji. He didn't have anybody else. He didn't want to end up with some stranger. He thought if he did that he'd go crazy after what Gin had put him through.

"Unohana I er... I have a confession to make." Hitsugaya stood, drawing aside the hospital gown so Unohana could see the scars Gin had made.

"Toushiro?"

Hitsugaya winced at the pitying tone. "I wanted someone to be with, but nobody really wanted a runt like me, or even thought I was interested in sex. Gin was... lusting after me, advanced on me and I figured why the hell not? Nobody would care. But Gin was... violent and... I thought there was something wrong with me, nothing he did felt good and... then he took his zanpakuto and... and he said..." Hitsugaya was struggling not to cry. "He said now I was marked, and nobody would want me because they'd know I'd been... used...."

"Oh Toushiro... you..." Unohana was crying? "Hitsugaya-taichou, you aren't the only person Gin hurt. I think you should speak to Izuru. I wouldn't even say anything, but as a captain you would have access to the file on the incident."

"I..." Hitsugaya's eyes widened, Gin had pulled the same... crap... with Izuru? Had that been before... or after...

He remembered very clearly, the reason why Gin said he didn't want to be with him anymore. "I've found someone much more entertaining, Hitsugaya-taichou. I don't need you anymore."

Hitsugaya sat down, hard on the bed, remembering Shinji's words also. "You aren't the only one he's hurt."

"How did you know?" Hitsugaya asked Shinji.

"People like Gin don't stop with one." Shinji replied simply. "Ukitake has offered us his tea house on the pond. Why don't we spend some time getting the place ready and getting some rest. I also think you should shower and eat. Get as much energy in your system as you can."

"Yeah, makes sense." Hitsugaya agreed.

At that point Ichigo ran in. "Is it true Unohana?"

"Yes, Zephly injected Hitsugaya and Yumichika both with the Fever Virus. Ikkaku and Yumichika have gone off into the woods outside of the west rukongai to revisit the place they got together in for the first time. They'll be gone for a week. Hitsugaya was discussing plans with Shinji."

"Looks like I'll have to put off your cero lessons."

"Alright Shinji. I just... wanted to make sure everyone was alright, and remind Toushiro not to shoulder his burdens alone. Especially after that incident with the King's seal. If it has arms to hold with, a heart to love with and a sexual organ to... aherm... sex with, then it was meant to have love in its life, man, woman, species doesn't even matter. If its capable of feeling love, then it deserves to be loved in return." Ichigo turned and left.

Hitsugaya spent the next couple of hours showering, eating, and finally making his and Shinji's bed in the tea house. "We could start early if you want."

"i'd rather save it for when the fever kicks in tomorrow." Hitsugaya yawned as he stripped and hung up his clothing near the door. Then he climbed into the bed, motioning for Shinji to climb in next to him.

Hitsugaya fell asleep quickly, and his dreams were plagued by minor aches and pains in his back and arms and legs.

The hard on and flushed face and body are the sensations that first woke Hitsugaya. The young captain had never been prone to morning wood before and it was strange to have an erection without having done anything to make it happen first.

Then he remembered, and sat up to wake Shinji. Hitsugaya wanted to test out this 'fever' and see if it was as stimulating as he'd heard.

And then he turned and looked in the mirror, and Hitsugaya's brain stopped working, just ground to a halt. Hitsugaya got up, naked, and walked over to the floor length mirror.

Hitsugaya had GROWN! He'd aged easily five years in one night! His body was slim, he had a six pack. His pubic hair had filled out a little bit, giving a nice thick bed of curls. The hair on his head was even spikier than he'd left it. "What the hell?" his voice had stayed more or less the same, just a tad deeper. "I'm... big?" Hitsugaya realized, he looked at least as old as Ichigo now, if not older. "in more than one way!" Hitsugaya licked his lips when he saw how much his cock had grown. It looked relatively /normal/ now, perhaps on the thick side.

Hitsugaya just stared in the mirror, he found his new body incredibly pleasing. He had /muscles!/ He had pubes! He could look /down/ at rangiku's busom now instead of having his face smooshed in her clevage.

Then Hitsugaya ran over to the bed again. "Shinji! Wake up! SHINJI!" Hitsugaya hissed.

Shinji groaned, rolling over. "five more minutes Hiyori."

"Its NOT whoever that Hiyori person is! ITS ME!" Hitsugaya had a few moments of doubt, what if shinji didn't like his new body?

Then Hitsugaya had an idea, he bent down and drew himself up against Shinji and kissed him. "Shiiiinnjiiiiiii..."

Shinji's eyes shot open. "Toushiro? Oh SHIT! Toushiro what happened to your..."

"I dunno, I just... aged... five years overnight!"

"More like six or seven. You think you look younger because the muscles on your new body haven't adapted yet. A few months of hard training and hearty meals in that form and you'll look a lot older." Shinji held Hitsugaya at arms length, taking in his changed body. "Wow... you look... good!"

"You like it?"

"Hell yeah! Its... hot... I mean you're hot no matter where you go or what you look like. But this is hot." Shinji wrapped his arms around Hitsugaya and pulled him close. "Though you won't have to worry about being too small for people to be interested anymore. You'll be dragging a trail of every gay man in Seireitei before long." He kissed Hitsugaya on the lips eagerly.

"You really think so?" Hitsugaya licked his lips, hands feeling their way along Shinji's body to his cock. "But right now all I want is you." He hauled Shinji down to kiss him. The only thing holding Hitsugaya back was the fear that Shinji might not like him in a grown up body. Now that that was over with. "Right now, I want that nice, long cock everywhere its possible to put it."

Shinji laughed, pulling Hitsugaya into a long, passionate kiss, twining their tongues. "I'll rock your world."

Hitsugaya grinned as shinji rolled him over onto his back and didn't hesitate to pull Hitsugaya's cock into his mouth, sucking on it, working his tongue over the underside and the head, massaging the sensitive parts with his tongue piercing. Hitsugaya moaned in pleasure, fingers winding their way into Shinji's hair and toes curling.

After a minute or two of licking and lapping at his dick, Shinji swallowed Hitsugaya's member and began to suck, hollowing his cheeks. Hitsugaya screamed in pleasure, crystaline eyes clouding in lust. His hips began to rock in time with Shinji's sucking, fucking the vizard's mouth eagerly. Shinji didn't seem to mind at all, moving his mouth in time with Hitsugaya's thrusts so that he wasn't choked.

Shinji throated Hitusgaya, humming as he did so and the tenth captain screamed in pleasure, bucking and writhing as he came. Almost instantly Shinji had a tube of KY Intense in his hand. The tingling substance stimulated his insides as Shinji's first two fingers wormed their way into his entrance.

Hitsugaya groaned, allowing Shinji to lift his legs onto his shoulders, the Vizard stretching and stroking the delicate skin beneath his fingers. Hitsugaya relaxed his body.

Shinji moved for Hitsugaya's prostate next, and just as Byakuya had with Ichigo he found a sensitive... spot... right beneath the prostate. He pushed against it, and it gave beneath his fingers, which sank an inch into something warm, wet and seemed cavernous beneath his fingers.

Hitsugaya screamed in pleasure in response, spots dancing in front of his eyes, the sensation was so intense his body began to shake beneath Shinji's fingers with the pleasure that rolled through his body.

Shinji was trying to figure out what he'd found, looking from his fingers inside Hitsugaya's body to his reaction and back. He tried thrusting his fingers in and out of the passageway he'd found. Hitsugaya screamed in pleasure.

This was new, and different, this wasn't there when he had sex with Hitsugaya the day before... and then Shinji's brain ground to a halt when he realized that what his fingers were pushed into was the womb created by the fever virus. So then...

Shinji kissed Hitusgaya tenderly on the cheek, removed his fingers, and then entered his koi, slowly, carefully. His initial thrust grazed Hitsugaya's prostate, causing the tenth captain to moan lewdly in pleasure. Shinji moved lower till he felt that one, extremely sensitive spot and thrust in.

Hitsugaya's mind had been racing just as much as Shinji's was and quickly came to the exact same conclusion. It was to increase the chances of getting pregnant. What concerned the captain was that he didn't care. The Fever was clearly affecting his judgement. He wanted Shinji in there.

The sensation of having his lover that deeply inside of him caused Hitsugaya to scream in pleasure. He almost came right then and there. And then Shinji started to thrust, and the friction of his lover's cock sawing in and out of that opening had the youngest of the captains writhing on the bed, white spots in his vision.

It wasn't very long before Hitsugaya came, screaming Shinji's name over and over and writhing on the bed. Shinji groaned, and a few moments later Hitsugaya felt his koi's erection slide in to the hilt and spill his seed directly into his womb.

Both men fell to the sheets, exhausted, Hitsugaya curled up against Shinji. It was morning, and he was drowsy already. "Sleepy..." Hitsugaya muttered.

"Then sleep Toushiro. I'll keep watch on you."

Why am I suddenly so sleepy? Hitsugaya wondered, Its not right, being sleepy again in the middle of the morning.

Its fine Master. Hyourinmaru assured him. You were given medical leave for this remember?

Yeah.... but.... Hitsugaya didn't finish the thought. He was out like a light.
