Chapter 1: Spring of the Dead

o-

Fifteen year old Harry Potter, boy wizard, was stuck in Japan with his 'loving' family, all because that stupid wannabe world conquering megalomaniac Voldemort attacked his school just before spring break, damaging the wards. Luckily he had been repelled, unluckily the wards needed to be repaired and the school could not be full of curious children while that was happening, lest they be turned inside out by magic itself.

Harry wasn't sure if Dumbledore had been joking when he said that, and he wasn't too keen on finding out. So, Harry and all of the students were sent home.

Now for a normal student, the Headmaster had no say in where the student spent his or her time during school breaks, but as he was constantly reminded, Harry's life was anything but normal. Since Harry was the ever hyphenated 'Boy-Who-Lived', his school Headmaster, as the less hyphenated but apparently more important 'Leader of the Light', took great interest in keeping him mushroomed - that being; kept in the dark and fed a lot of bovine excretion. So Harry was stuck in Japan with his relatives because Dumbledore felt the need to ruin Harry's life.

The reason for being in Japan was that Vernon was at a drill convention, his boss at Gunning's chose his top five men and Vernon had mysteriously managed to shoot up the corporate ladder to place fifth, where before he was barely able to hold onto his position somewhere in the top 100. How mysterious...

So, Harry was stuck in Japan for the foreseeable future. Thankfully for Harry, he was able to get his own room and avoid his family; a setup everyone agreed was the best way to do things.

Honestly, the trip so far hadn't even been that bad!

**Flashback**

When Harry got off the train from school he was picked up by Vernon.

"Boy when we get home you are to pack one small bag and only one small bag, unfortunately that Bumblebore fellow is forcing us to take you on my trip to my Drill Convention. Since this year it's in Japan you will stay in the room and not make any noise."

"I have a better Idea. My parents left me some money, at least enough to get through school and a bit more. You will bring me to Charing Cross road, I will take out money, and once we get to Japan I will disappear and you won't have to see or deal with me until it's time to go home." Harry counter offered.

Harry's deal would have went over flawlessly if it wasn't for one thing; Vernon's greed.

"You will give me all that money or you will regret it." The man demanded.

Harry's jaw clenched. Well that was a failure. "No. You can come with me to the bank if you'd like, but you'll find that you couldn't take a single galleon from me if I didn't want you to. The Goblins, they run the bank, and they have this policy about thieves, and considering what you've been doing since you took me in..." He trailed off, waiting for a reaction.

He wasn't disappointed.

Vernon started spluttering, face going both pale and purple at the same time. It was sickening to look at, but Harry took satisfaction in it all the same.

He continued, "Yeah, my Trust Vault has been used to send you money for my care, you've been using it completely for yourself. Lying to me, calling me a burden, when you get enough to get a new car every year on TOP of all the latest gadgets for Dudley?" Harry gave a cold chuckle, enjoying watching Vernon squirm. "I don't think so. You're lucky I'm willing to let this slide as is, would you prefer I file a claim to get all the stolen money back? I hear Goblins have a liking for drinking fine wines out of the skulls of those who don't have enough to cover their debts."

Harry smirked as the purple dropped from Vernon's face, all that remained was a ghostly paleness.

"In fact, the goblins went through my memories in my third year and calculated all the work I've done for you that went unpaid. Learned a LOT in third year, actually. Which is why you no longer get money ten months of the year." He didn't think he could get any more satisfied with how this talk was going, so he allowed a bit of smugness to sink into his posture and voice and gave his ultimatum again. "So take me to Charing Cross Road, I will get what I need, and when we get off the plane we won't see each other until the flight home."

"Fine." Vernon turned the car in the direction of Charing Cross Road.

Harry got out of the car and turned to look over his shoulder, "I won't be long."

"Like I have a choice?" Vernon said quietly, still shaken.

Harry shrugged and walked into the Leaky Cauldron. Nobody even looked up as he made his way to the back and went through the arch to Diagon Alley. There, he meandered his way to Gringotts to get some things he knew were in his vault. It was a good thing for him fifteen was the youngest he could take items out of the main vaults.

"I need to talk to Snapclaw." Harry said to the teller when he reached the front of the line.

"Fine, you know the way I assume?" The goblin growled.

"Yeah, thanks." Harry nodded and walked to the back of the floor through an archway to the offices in the back. Snapclaw's office was easy enough to find, having the Potter emblem on the door, since he oversaw those accounts.

He knocked, got a positive response, and entered. Without preamble he started speaking. "So my relatives are going to Japan, my oh so caring Headmaster is forcing them to take me with them. I have no passport and would be detained instantly. Something that seems to have slipped the old man's mind. As such I need a few things; a passport, a decent amount of money in both Pounds and Yen and lastly that Enchanted Translation Ring in my vault." Harry said before finally sitting down in the chair before the desk of the Goblin that had been so monumentally helpful in his third year.

That day, in the summer before third year, had been a barrage of surprises, the first of which being that the Snapclaw hadn't met him at Gringotts, but instead at Florean Fortescue's Ice Cream Parlor. Apparently the Goblin had a sweet tooth he didn't get to satisfy very often.

After an exhausting talk, Snapclaw had ordered a unique form of ice cream with a Roborante* potion mixed in before they had done a bit of shopping. Snapclaw had a great deal of advice on what to get to best maximize his wealth, and had wanted to make sure Harry followed them perfectly if he so chose. First had been a trunk, complete with a mass of compartments for plenty of room and several dozen features that would make it undetectable and easy to travel with.

After that had been purchased, next had been the bookstore. The fact that it took them four hours to get everything needed was testament to the amount of material Snapclaw wanted Harry to be familiar with.

But now, in the present, he needed several things from the Goblins and he needed them fast.

Harry was out the door in fifteen minutes, immensely satisfied with the service of the bank, though calling it just a bank seemed rather lacking considering all Gringotts could do. With everything he needed, as well as some info on Voldemort and his experiments with Inferi - why anyone would experiment with the walking dead Harry had no clue. Regardless, a quick stop to get a wardrobe that would help him blend in, with all the bells and whistles that magic allowed of course, he headed back towards the Leaky Cauldron.

He found Vernon parked where he'd left him, looking a far healthier shade (still pale for the man, since his usual tone was far from healthy, but progress) and surprisingly neutral when Harry stepped into the car.

"Take long enough, boy?" The man grumbled, apparently not able to help himself.

"I needed a passport. Would you like to be arrested because they think I'm a terrorist and you're an accomplice?" Harry sniped back, seeing no reason to tell the truth. Harry however dropped a package in Vernon's lap. "Portkeys. If you are in trouble the password is Sanctuary."

"..." Vernon remained silent as he shifted gears and pulled out into traffic.

**kcabhsalF**

Thus two days later they were in Japan and Vernon was schmoozing with other drill salesmen, incident all but forgotten. Harry, on the other hand, was bored out of his skull.

They were in a small little place called Tokonosu City, which was NOT a tourist attraction and the absolute lack of attractions made it show.

Presently, Harry was wandering the town, thoroughly lost. Too bad it was the middle of the night - closer to morning, really - but something was nagging him badly, especially about the guy coming towards him. He noticed that the man was walking kinda like the zombies in video games an-'Is that a bone sticking out of his leg?!' The lack of blood was even more damning proof.

Harry was glad that he was able to get an exemption to use his wand after totally out maneuvering Fudge and his lackey (and the newest inmate of Azkaban) Umbridge, during his trial. A quick Reductor at the Inferus' skull made quick work of it.

Of course then again there were three more coming his way already, as was the nature of most Inferi infestations.

'Okay, now's the time for running.' Harry decided as he took out his broom and flew up high. He was so focused on the zombies mindlessly groaning and raising their arms, the ones that worked anyway, that he almost didn't notice the beeping coming from his pocket. He initially thought maybe it was his alarm clock and he was about to wake up, but it turned out to be the Goblin communicator Snapclaw had insisted he take just in case his most profitable client needed something on the fly.

"Harry here?" He answered absently, hovering in place and looking around. He had absolutely no idea how he missed the chaos before. Things were on fire and there was plenty of smoke rising from various points around the city.

The goblin, as most of his race did, started in on business right away, harsh voice a characteristic growl as he explained, "Potter, that moron Riddle lost control of his Inferus. Not just in Britain but all over the world."

"That would certainly explain the walking dead. I have about ten meandering about below me." Harry deadpanned.

"Well the good news is that Magicals are immune to their bite, or at the very least highly resistant. The bad news is that a single bite, or even a scrape of teeth hard enough to break the skin, is enough to infect a non-magical. That happens, it's over for them; just a matter of time. Contact that godfather of yours, these Inferi are still blocked by Undead Wards so most magical places are safe from them, for the moment. If Riddle has even a single smart follower they're going to try to tear down those wards when they recover from this accident." Snapclaw cut off the communicator and got back to helping the rest of the Goblins trying to fix this.

Harry snapped his communicator closed and placed it back in his pocket. "Right, get Sirius on the line." He reached into another pocket and pulled out the communication mirror Sirius had given him and called his name. "Sirius, you there?"

"Yeah Harry, things are going crazy out in the Muggle world." Sirius commented, voice distant enough for Harry to assume he was either watching or reading something.

"It certainly is here in Japan. The Goblins say that Voldemort created a new kind of Inferi. Good news is that bashing it in the head destroys it, the bad news is it's immune to fire and one bite turns a non-magical into one of them." Harry flew up higher. "We're mostly immune; from what Snapclaw hinted there might be some unlucky bastards that could still be turned, so don't go getting cocky. Even if we are immune though, that won't save us if every Muggle turns and we have billions of these things hammering on our doors."

Sirius seemed shaken by the thought, "Right, well, your friend Hermione and her parents arrived an hour ago or so. Apparently there was a nest of them near her house and she noticed something wrong and used her Portkey here."

"That's good, I wouldn't want her to lose her parents in this." Harry sent another Reductor into the group of Inferi below him. "Well I'm going to look for survivors. If my relatives were lucky they used the Portkeys I gave them to my house in Wales. But I don't know if they did or not."

'Kinda hoping they didn't.' A part of Harry thought viciously.

He picked up again after the momentary pause. "I'll give Portkeys to survivors to my estate here; the Statute of Secrecy is fucked anyway and I'm willing to bet the local government is going to be doing the same thing once they get their forces mobilized." He chuckled, "Glad my family was so spread out and I still have cousins here though, albeit very distant ones. See ya Sirius."

"Sure, come home soon." Sirius ended the call.

With the broom firmly between his legs and wand at the ready throwing around Reductor curses like it was going out of style, Harry began flying around and finding as many groups as he could that had barricaded the doors and stairways to various establishments and homes. It was simple to do, Muggles couldn't actually see magic once it left his wand, so even the stubborn groups fell to a compulsion charm or two to hold onto the hoops he kept for Portkey travel. He just loved the Potter family Library, it had the most interesting books - even a Grimoire - which had lots of spells and suggestions on how to use them. Granted he mostly just hit the Portkey with a sticking charm and tossed it, since he had so many hoops in his bottomless bag, but it was still very useful to have a Portkey that could also have other spells placed on it. The standard spell reacted quite violently to tampering.

As Harry wandered through the city on his broom he noticed the sun rising. He continued wandering around the town watching the chaos and helping where he could until he came to a surprisingly calm area. He flew over the streets and finally saw a well-armed group of people driving in a convoy towards a mansion. He landed on a side street put his broom away, no sense in scaring these people. And walked out to the main road where he saw the convoy.

The group of vehicles stopped as Harry stepped out into the street. "Hi, are you going to a safe place?" Harry asked

A man with a militant air about him stepped out of the front vehicle and nodded to him.

"I'm Harry, I know of another safe place that could use some direction. Can we use your safe place as a staging ground to the other one? The one I know of is safer than anything else because these things can't get in no matter what."

"Come with us and we will discuss this." The leader of the convoy said.

"Thanks, it's kinda scary out there on my own even if I do have ways of protecting myself." Harry jumped into one of the vehicles and rode with them to a lovely mansion with dozens of large tents on one side of the lawn.

The straight laced man gestured for Harry to follow him inside. When they got there they were met by a lovely red-violet haired woman. "My wife Yuriko. My name is Soichiro Takagi."

"Harry Potter, pleased to meet you." Harry bowed to the two adults before they all sat at a large table half covered with plans.

He started things off, telling his tale. "My relatives and I came here for my Uncle's drill convention and I got separated from them, intentionally - we don't get along. But you wanted to know more about the safe place I mentioned… It's about ten miles north of the city in the mountains. It's part of my family's holdings, not the relatives that I came with; they're from my mum's side and never liked my dad, or my mum for that matter. But my dad has family all over the world, so the collective family maintains holdings all over the world. As I'm the last of the main branch I have control over it all, but my cousins help a lot."

"Very well, your story is interesting so far, how would you transport everyone there?" Soichiro asked.

"Well that is part of what I need to show you. I also have information on how this outbreak started, let's just say an idiot was tinkering with things he shouldn't and lost control... for now." Harry pulled out his mirror. "Sirius Black"

"What's up kiddo?" Sirius said from the mirror, the two Japanese jumped.

"Well I made contact with a group that seems to know what they're doing and are bringing people together, I assume that while things are good now dissension will start up when everyone thinks it's safe... even if it isn't safe." He commented with a sigh. "So I thought that we can make it safe enough that it wouldn't' matter. The adults in charge need an explanation for everything and I figured you, an adult, telling it would go over better than a kid telling it." Harry explained before he passed the mirror to Soichiro, who took the familiarly shaped but bizarre device gingerly.

"Hi, I'm Sirius, Harry's godfather. And this is a magical communication mirror that Harry's Dad and I made in School. The school we went to is Hogwarts School of Witchcraft and Wizardry. And yes Magic is real."

Soichiro, never a man to lose his cool, took the realization in complete stride. "Well that is quite the introduction… if you were sitting in front of me telling me this I would worry about your sanity. I can see why Harry wanted you to tell us. I'm not sure that we believe it even now."

"Well that's the thing, I can show you the estate and then we can come back here and that would be a much better show than the mirror." Harry pulled a ring out of his bag and enlarged it.

"Portus" He incanted, before he held the ring out the Soichiro and his wife. "Would you like to see my home here in Japan?"

The married couple glanced at each other briefly before they turned back to him and nodded. "Yes." They both took hold of the Portkey as Harry scooped up the mirror.

Seconds later Harry landed on the floor of a grand entrance way in a heap and Soichiro and Yuriko both landed in crouches on their feet. "Ugh, I hate portkey travel…." Harry's voice floated up from the floor.

Yuriko put her hand up and snickered, and Soichiro let out a full laugh. "I see that you do have trouble staying on your feet at least."

"Got any pointers?" Harry asked as he stood up. "I hate Floo too." Harry looked around the room. "Wow, this is the first time I've ever been here. It's great, perfect looking for what we need."

"Have you sent any others here?" Soichiro asked.

"Yeah, but not to the main house, I sent them to the guest house which I understand is set up like a resort about a mile from here. I know there is a cousin here somewhere and several house elves." Harry jumped back as an elf popped in and bowed.

"The master is here. The master has sent many people here, what does the master want to do with these people?"

"Well I was hoping to set up some homes for them and help them turn at least some of this place into a temporary town. I understand that this estate is several miles in the real world and also copied several times over in the Fukuhan** right?"

"Yes Master Harry this could be done. The people you sent though are not happy, they don't understand why you sent them."

"What? They don't understand that I saved them from a Zombie Apocalypse? Or they don't believe that they were saved?"

"They don't know what to think Master. Cousin Master is trying to understand too but Cousin Master Kentaro does not know either. And the Teribi is not making any sense."

Harry sighed and turned to his guests. "Mind If I take care of this?"

"How about we take care of it, they may listen to us better. I am fairly well known, they should have at least heard of me." Soichiro and Yuriko left the building with Harry following.

The trio got into a car and drove to the 'Resort', the trip not taking long at all since the road was straight, flat, and magically spelled to be completely clean of anything. Once they arrived Soichiro was in his element, explaining what was going on to the people. He effortlessly convinced them all that Harry had probably saved their lives, Soichiro had seen many places that had been barricaded but broken into even still, his impassioned speech about how happy he was so many people survived won over the last of those that were still fit to make a fuss.

He finished off by telling them all the tentative plans to set up a village, and finished off with a rallying cry announcing that many more survivors were expected to show up, safe and sound.

A quick word from Harry had the man stepping back up and requesting aid in organizing everything since Harry understood that he was rather young to be doing it himself – he had the know how, sort of, but the charisma he would need to get people to look past his age was something he didn't possess. Maybe in the magical world, since people saw him as a symbol or some nonsense, but not here.

Giving a brief introduction to the crowd, Harry gave a general description of the Portkeys used, making sure to emphasize the safety of them, and the protections around the estate. The people were incredibly relieved to hear that the protections not only kept out the Inferi, but also those infected. Those poor souls would be bounced off the wards around the property and sent right back to where they started when the Portkey picked them up.

o-o

Several hours later Harry and the Takagi's returned to the Takagi estate, and Soichiro started organizing an evacuation, sending everyone who wanted to go, which was most of the refugees, to the Estate. The rest decided to help calm down new refugees. Harry spent the next few hours creating Portkeys that could be enlarged to ten times their original size and activated with a word. He had no intention of staying with the Takagi's forever, he planned to use his broom to find others that the Takagi's may not get to in time or something- he hadn't decided yet.

The next morning Harry woke to a commotion of a group of people near his own age joining the estate, as well as finding out that the Takagi's had a daughter and she was among this group. He watched them for a bit and decided, based on their personalities and the way they carried themselves, that they wouldn't stay. They had a taste of freedom from adult rule and they would not go back under it. He went to see if they would let him join them.

After talking with Takashi and his friends he found that they were willing to have him especially after he demonstrated an air whip - similar to a fire whip but made of air particles strung together to razor sharpness. The new Inferi, which Takashi and his group called Them, were rather resistant to fire and the flame whip. Harry found that out the hard way after looking it up in the Grimoire during his travels. Thankfully it was easy to master the Ventusflagellus or Airwhip, even more so after mastering the Ignisflagellus or Firewhip, since they were essentially the same spell with a slightly different feel.

The next few days were spent sending refugees to his estate and making more Portkeys. Harry also warded an abandoned building with the Undead Repelling Wards and created a permanent Portkey to that place far away from any muggle electronics - though his magic had not been interfering at all anyway, he thought it better to be safe than sorry.

Then the EMP wave hit.

Harry had been in the warded building when it did, stocking up on voice activated Portkeys. He felt a shock run through his magic and ran to the estate. In his dash he caught sight of the Inferi making their way through the streets. Streets that were supposed to be undead free, due to various barricades set up to keep them out.

He skidded in through the gates seconds before They reached it. It didn't take more than a glance to see that the gate wouldn't hold for long.

He tossed three separate Colloportus, locking spells, at the door and linked two halves of a unique charm that turned mass into explosive force. The second the gate wasn't touching the wall keeping it in place, the gate's metal would disintegrate, turned into energy to power an explosion. It was risky, but he was confident he could get everyone nearby out of the blast range before the undead broke through.

In the name of that goal, he turned and began yelling at everyone to grab a Portkey, handing them out like candy on Halloween. Most of Takagi's people were firing at the Inferi, keeping the monsters from actually putting any force into knocking the gate over. It was a losing battle, as one of the three locking charms had already been overpowered, but they were buying much needed time.

By the time the second fell, Harry had given up on calling out to people and was literally hurling the Portkeys at people.

When he finally finished giving out the last transportation device, he saw the other teens and sprinted over to them. They turned back to look at him as he hopped in the buggy right behind them.

Saya was the first to speak, or at least the loudest and most commanding. "My parents?" She queried.

"They're out. Anybody left out there can Port out at any time, and are probably only there to buy just a bit more time." Harry answered hurriedly. He had no idea when the gate was going to blow, and he would like to be gone when it did.

"And what about their plans to save as many people as they could?" Takashi asked.

"I made a small safe house Warded to keep the Inferi out filled to the brim with Portkeys. Saya's dad can Port in and out with as many people as he wants and that can be the new staging area. There were some cars there, but I'm not sure they were protected from the EMP – my wards might or might not diverted them." Harry rambled rapidly, looking over his shoulder. "Look, we need to leave, like now." He said blankly.

Kohta perked up, "Wh-

He was interrupted by an earth shattering explosion, the buggy actually briefly balancing on two wheels from the force.

"That's why!" Harry said loudly but blanky. "The gate's clear, but that's going to attract a whole hell of a lot of them!"

Shizuka nodded and slammed on the accelerator, tearing out of the garage and through the gate, the large tires easily able to overcome the rubble that used to be the walls, sidewalk, and even a bit of road.

Once they were clear Takashi turned to look at Harry. "Okay, can you make us Portkeys to my home?"

Harry shrugged, answering. "I either need a Portkey to the place that I can copy or I need to have been there. While I feel like I've wandered all over this town in the last week or so I'm sure I'm not even close." Harry explained.

Takashi nodded, not happy but satisfied with that answer

The group continued on towards the highway where they ran into a snag. They were forced to split up. There were just too many Inferi to bring the buggy, so Takashi and Saeko took it one way, attracting attention, and the rest continued on foot.

Harry took point and cleared out any stragglers with well-placed Airwhips. They were, thankfully, much less noisy than reducto. He normally wouldn't care about noise, but he had people to protect now, and the two heaviest hitters were elsewhere when it came to melee combat.

They made it to the agreed upon meeting point, a nearby mall, with relatively little fuss thanks to the distraction the buggy had created. Harry still secured the door behind them when they had piled in though, no sense in leaving a weakness uncovered in case they were actually being followed.

Revision

08/07/15

*Pepperup is for colds so I created a NEW one called Roborante Potion Which SHOULD be Invigoration Potion just cause It pisses me off when people use Pepperup as an energy drink. (BTW: if you read this before the revision I did not put pepperup in I think my beta suggested a energy potion and we used pepperup as a substitute/placeholder. I just reread and it annoyed me so I changed it.)

**Fukuhan=Duplicate I figured that is is a Japanese magical thing that the Potters brought to the rest of the world. After the Latin world is not the be all and end all of the magical language.(I originally called it the Double but that annoyed me today as well.)
