Now let me give you the run down on what this story is about, it's essentially the HOTD with added characters from my favourite anime one piece which are primarily the straw hat crew, Boa Hancock, possibly Tashigi, and my 2 OC's Emerald and Sapphire, please let me know what you think of pairings for Zoro though, I'm thinking either Zoro X Robin or Zoro X Tashigi, let me know what you think, feel free to submit ideas for future chapters because I plan on heading out on my own after chapter 13, I have an idea for chapter 14 half sorted, Also those with either devil-fruit powers, are a cyborg, skeleton or reindeer are basically failed or experiments overall, those backstories will come later, Emerald is one of them (experiment for a genetically modified super-soldier like captain America only failed and allowed him the ability to manipulate his body beyond ways humanly possible, again more backstory later but he has been trained in swordsmanship by Zoro and Blackleg style by Sanji and is a fast learner, that's all I'll say) anyway read and review please no flames. I also have some modifications to adjust for the extra people. (Accepting ideas for pairings, so far I've got Luffy X Hancock and Sanji X Nami) possible lemons for later chapters but don't get your hopes up.

I do not own HTOD or One Piece I only own my OC's

(I stayed up late…the night before it all went to hell)

We see four kids running on the roof of what appears to be a high-school that's covered with undead beings the first one was a male with black hair holding a baseball bat, the next one we see was a female with orange hair holding an improvised spear made from what appears to be a mop handle, the third one was another male with greyish hair and a bandage on his arm, the final one is yet another male with spiked green hair armed with an improvised staff or club, could be a golf club but where would they store that in a school. Anyway they run to a set of stairs taking out anything that got in their path about half way up the stairs the girl turned around and stabbed one of them in the heart.

"ARE YOU NUTS?" the black haired male asked as the orange haired girl gave him a confused look before her spear was shaken lose from her grip and brought back slamming her into the wall before another one of them started crawling towards her. As she screamed the grey haired male grabbed the baseball bat and bashed its skull.

"Did you see that? You have to smash their heads to kill them" the male explained as he bashed the other one.

"Thanks Hisashi" the girl said as she got up

"Rei, Hisashi, come on" the black haired male called from the top of the stairs as the two ran up the stairs with the girl we now know as Rei holding Hisashi for support. "Damnit" the male muttered as they turned the corner and he turned back to face the horde "WHAT THE FUCK IS GOING ON?" he yelled.

Now let's go back a few minutes to when everything was still right with the world. We see our black haired male on an open stairwell overlooking the front of the school looking depressed.

-Flashback (a few years first person POV (Black haired males POV))-

We appear to be in a kindergarten setting "We're going to get married one day" a younger version of Rei says.

"Really?" you respond

"Yea, pinkie-promise, cross my heart…" she starts as you both put your hands out.

"And hope to die" you finish as you seal the deal

-more recent flash back (third person POV)-

"Why do you have to repeat the grade? You're a straight A student" the black haired male inquires.

"You wouldn't understand Takashi" Rei responds as she walks off.

-Another flashback (classroom setting)-

The grey haired man looks back and smiles while saying something to Rei.

-I'm sick of these flashbacks continuing with the present day-

"Pinkie-promise, cross my heart, and hope to die" he repeats before scoffing "Yea right"

"That's so stupid" a voice says causing Takashi to look up.

"What do you want?" he questions to a female with pink hair tied into two pig-tails I think they are, (I don't even know what the style is called (HELP ME FIGURE IT OUT))

"Every time you have to face something you always come to this stupid stairwell, it's like your own pity corner, for god sake the first semester has just started how are you ever going to make it through the year" the pink haired girl rants as Takashi diverts his eyes.

"That's my problem, besides I could ask you the same thing the fifth period isn't even over yet" Takashi responds as she rants about how she's a genius and how stupid Takashi is. "Answer me this Saya, why do you always diss me like that?"

"Because I don't like stupid people" the pink haired girl now revealed as Saya responded as Takashi just turned his head "Oh grow up, moping because your little friend dumped you is so stupid" and with that she turned and left leaving Takashi with his thoughts. A few moments later a rattling at the school gates shook him out of his thoughts he turns to see a figure banging at the school gates as a few teachers go to check it out.

-With the teachers-

"You there, what do you think you're doing, this is a private school" a woman asked as the man at the gate just stared blankly.

"It's ok Miss Asashi let me handle this" a male said as he rolled up his sleeves walking towards the gate. He grabbed the figure by the collar and pulled him causing it to crash into the gate.

"Now…uh Mr Tashima excessive violence…" she started before the unthinkable happened. The figure at the gate took a chunk out of the PE teachers arm causing him to fall back. Leading Takashi to stare in shock. After a few seconds the teacher was proclaimed dead before he attacked one of the bystanders. This lead Takashi to run as the teachers attacked each other. He ran down a corridor to Rei's classroom before slamming the door open and panting heavily. He walked over to the desk Rei was ad before grabbing her arm.

"You have to come with me" was all Takashi said as Emerald who was in the very back row came down to see what the fuss was about immediately before Saya and Hisashi got up.

"Dude what are you doing?" Hisashi asked.

"People just got killed by the front gate, no joke" Takashi responded as Hisashi gave a shocked expression.

"Are you fucking serious?" Hisashi responded

"Yea I'm really going to make up a lie about shit like that" Takashi responded sarcastically

"What the hell is going on I can never understand…" Rei started before she was slapped "What…"

"Just fucking listen to me okay?" Takashi shouted as he looked to Hisashi who gave a serious look before the three of them started heading down the hall with Emerald close behind.

"So…" Emerald panted "Do you think it is what I think it is?" Emerald questioned

"I certainly hope not but it's better safe than sorry" Takashi responded "All I know is there was someone at the school gate, teachers went to check it out and something happened, and now they're killing each other"

"That's insane" Rei interrupted as they reached a supply closet. On accordance of Hisashi "What now?" she asked getting annoyed.

"If what Takashi says is true we'll need weapons" Hisashi responded giving Rei an improvised spear, Takashi grabbed a baseball bat and Emerald took a golf club, hang on, what's that doing in a supply closet.

"What about you?" Takashi asked.

"I'm a black belt in karate" Hisashi responded "Now we gotta move, we need to get out of the school"

"I'll call the police, we can speak to my father" Rei said as Hisashi handed her a phone.

"School rules are meant to be broken right?" he asked rhetorically

"Amen to that brother" Emerald said as he fist pumped the air. Rei dials the number and waits only to get it sent to voicemail or whatever due to a high call volume

"He's busy" Rei said with a worried expression as an evacuation announcement came out over the loudspeaker that ended in screams.

"It's happening" Takashi mutters.

-Meanwhile in another hall-

Two people are crawling out of a classroom, one rather large kid and one skinny one with a long nose

"Hirano" Saya called followed by a girl with long blue hair causing the two of them to jump.

"Oh, hey Takagi, Sapphire" the large one responded.

"We've gotta go" Saya said as she got Hirano moving.

"WHAT ABOUT ME?" the long nosed one called.

"Sorry, but I need you to prove your useful and not just cowardly before I take you along Usopp" Sapphire said as another woman with long black hair appeared behind them "You coming Hancock?"

"I don't know why we have to take this man along but I guess, let's get outta here" the woman responded.

"You will regret not taking me along" Usopp called as he ran in the opposite direction. All over the school loudspeakers were ringing with screams, the dojo where 3 people got up holding training swords, one with three of them, the cafeteria where a 2 males, one with a straw hat, ash coloured hair and a red vest, and a blonde with a cigarette swirly eyebrows wearing a black suit, the mechanics class where a guy with blue hair (I'm adding some of these rooms) and star tattoos on his arms, (if I'm getting any details wrong please correct me with a review), the nurses office where a racoon dog (insert chopper saying, 'I'm not a racoon dog, I'm a reindeer' here) and a blonde woman were napping raising their heads slightly at the sound, the music room where a skeleton with an afro was playing a violin, an orange haired girl who was in art class stopped her work and looked up and the library where a long black haired woman was peacefully reading perked her head at the sound (Let me know if I forgot anyone). Then the screams of the loudspeaker went silent and the halls were filled with screams, pushing and shoving.

-Back with Takashi's group-

Hisashi started running "Where are you going?" Takashi asked "WE NEED TO GET OUTTA HERE".

"The classroom halls are filled, we need to take the management building" Hisashi explained

"Hisashi's right" Rei explained "So just shut up and listen to him"

"Ok fine" Takashi grunted

"May I make a suggestion?" Emerald asked.

"NO" they all yelled

"Fine, ignore the guy who spent his whole life preparing for this" Emerald muttered as he followed them. Once they reached an open hallway they saw someone

"That's Mr Makisako, what's the matter with him?" Rei asked as upon closer inspection he appeared almost dead. The teacher then stumbled towards the group attempting to attack Rei who continuously back stepped swiping her weapon "Stay away from me"

"Rei, Stab him and don't hold back" Hisashi called as Emerald face palmed. Rei shook the thing off before getting into battle stance.

"DON'T YOU DARE FUCK WITH ME" she yelled as she ran at him using blunt attacks before stabbing him in the heart only for him to keep moving.

"REI" Hisashi yelled as he jumped on the back of the teacher

"IDIOT" Emerald yelled.

"PUll IT OUT REI" Hisashi yelled as Rei pulled the spear out.

"Hisashi, what about you" Takashi called

"Don't worry I can take him" Hisashi called back as the thing started rotating its head back to a point no human can.

"NO, NO, NO IDIOTS" Emerald yelled as he face-palmed yet again while Hisashi tried to turn its head back.

"What the hell?" Hisashi grunted as the next second there was the felling of teeth on his flesh trying to bite through. With Rei trying to stab the thing and Takashi standing in shock momentarily before beating his baseball bat against the back of the thing. Emerald groaned and decided to react but all too late, the teeth ripped out a chunk of Hisashi's shoulder causing a cry of pain to sound just before he delivered a powerful kick to the things skull busting it open.

"Why didn't he die sooner?" Rei asked as the others except Emerald shrugged.

"My assumption was correct i can safely say" Emerald said causing Hisashi and Rei to turn his way with Takashi to follow suit slowly seeing as he already knew what was going on.

"Ok so NOW you listen to me" Emerald sighed, "That thing we just killed isn't human, well it is, but it's technically speaking it comes under a completely different category." Emerald explained as the group found an opportunity to catch a breather.

"Ok then Emerald, why don't you enlighten us" Rei sneered

"They're Zombies, there are numerous causes for this that i could go on all day explaining but the most common explanation is an evolved type of virus that somehow enters the human body, I'm not going into details but the most common way it spreads is often by infected persons biting someone like us, from what I've read, if your bitten, you turn, essentially saying you're a goner" Emerald continued "To kill them it takes a powerful blow to the skull or a well-aimed head shot to kill whatever brain cells are left"

"Well shit, if what you say is true Emerald you may as well toss me off the balcony from up here" Hissashi groaned.

"Calm down Hisashi you're not going to turn." Rei comforted

"Well, there's also the possibility you die of blood loss considering he took out a huge chunk of muscle tissue from your shoulder" Emerald added.

"Not. Helping" Rei says slightly annoyed as she ties a piece of cloth around his shoulder.

"JUST BEING REALISTIC" Emerald called defensively "Now come on, we've gotta move any ideas on a location?"

"The roof." Hisashi suggested

"The roof?" Rei asked

"We should barricade ourselves up there until help arrives, then find out what the hell is going on" Hisashi explained.

"DID EVERYTHING I JUST SAY GO IN ONE EAR AND OUT THE OTHER" Emerald yelled as they started running ahead "It's a good idea and all but i just explained what's going on" they continued till they reached a railing that overlooked the chaos below.

"Holy shit doesn't look like anywhere is safe" Takashi spoke up after a few seconds

"Sweet Jesus" Emerald responded not long after

"But a minute ago everything was fine" Rei spoke in disbelief as a strong gust of wind picked up while Blackhawk helicopters flew overhead.

"American military?" Hisashi questioned.

"No, that's self-defence force" Takashi corrected "Though there's no base around here, so where the hell did they come from?" meanwhile Rei was trying to flag them down.

"You really think they can hear you?" Emerald asked "Besides, they probably have other priorities"

-Meanwhile in the school halls-

Everything is going crazy, BFF's turning on each other, someone committing suicide, complete madness, while our dojo trio stand overlooking a stairwell inside the building.

-Back on one of the roof tops-

"This is some crazy shit, dead people attacking left and right, like some sort of video game, only this is the real shit" Hisashi said as the group overlooked the school now filled with those things. As they turned back to their target they found a large group of undead blocking their path.

"There's too many of them" Rei pointed out.

"Doesn't mean it's not impossible" Emerald said with a determined look "One way or another we've gotta get to that roof"

"Ok, on my mark...GO" Takashi yelled as the four then charged to their destination taking out any undead in their path.

-And this is about where you came in-

We now see Emerald finishing off the barricade to their location "Done" Emerald said dusting off his hands.

"Why is this happening?" Rei asked to no-one in particular

"Only god would know, if this is his doing" Emerald answered "That aside all we can do now is protect ourselves" as Hisashi started coughing blood...black blood.

"Hisashi" Rei gasped with worry as she ran over to him "Emerald, Takashi do something Hisashi is..." she stopped when she realised them staring blankly at Hisashi. Emerald then sighed.

"If he was going to die of blood loss that would've happened by now" Emerald said looking at the ground as Hisashi leant back against the railing breathing heavily "Hisashi, you okay mate?"

"You were right Emerald" Hisashi responds through heavy breaths "You're bitten, you're gone, just like the movies"

"HISASHI, DON'T SAY THAT, EMERALD ALSO SAID..." Rei started before she was interrupted.

"I ONLY SAID THAT TO MAKE YOU FEEL BETTER" Emerald yelled causing Rei's eyes to widen in shock "There's nothing we can do for him now, he's been infected"

"HE'S NOT DOING TO TURN, YOU'LL BE FINE...RIGHT...HISASHI" Rei asked worriedly as more black blood was coughed up by Hisashi.

"I wish i could say otherwise" Hisashi responded "Rei, can you do one thing for me...throw me over the balcony, i don't want to become one of them"

"YOU'RE NOT GOING TO TURN INTO ONE OF THEM" Rei yelled.

"It happened to everyone else who was bitten, so why shouldn't it happen to me?" Hisashi asked. However Rei still denied "Ok then, Takashi *cough* will you do it for me?"

"HISASHI" Rei cried as more blood appeared.

"I DON'T WANT TO BE ONE OF THEM DAMNIT" Hisashi yelled as he coughed twice more before collapsing unconscious. The other two males watching as Rei cried in denial.

"Get away from him Rei" Takashi said plainly.

"HE'S NOT GOING TO TURN" Rei yelled as Hisashi got up with a cold look in his eye.

"Hisashi?" Rei asked as Takasshi tightened the grip on his bat.

"Any advice Emerald i can't bring myself to kill a good friend" Takashi asked as Rei backed up while the newly zombified Hisashi shuffled towards them.

"No-one wants to live a life of endless hunger" was all Emerald responded with.

"What does that mean?"

"Don't think of it as killing him, think of it as setting him free, by killing him now, you're doing him a favour" Emerald said as Takashi nodded then charged at Hisashi bashing the bat against his skull killing him instantly as Rei screamed. Moments later Rei was sobbing by Hisashi.

"Jealousy" Rei muttered before looking at Takashi "I bet you really hated Hisashi, since we were dating and all" and as those words were spoken Takashi started walking off after talking to Emerald

"I'm going for a walk" was all he said before he continued towards the barricade.

"Where too? There's nowhere to walk to" Emerald called after him as Takashi turned to face the duo.

"If I'm going to die I may as well die fighting, besides Rei clearly doesn't want me around" at that Emerald sighed

"Wait, you can't take on that many, not alone anyway, besides, I believe you need to know how I know about this shit" Emerald called after him causing him to stop "Both of you do, Rei in particular" he finished as Rei lifted her head to face Emerald "Rei, before I start I need you to know that I know how you feel, if not experienced a higher level of emotional pain"

"How is anything more painful than losing someone you love?" Rei asked

"True, but compared to a boyfriend, a whole family, correction, having to kill your own family is a whole different level of emotional hurt" Emerald said as Rei's tears stopped momentarily while his started up "It all started a few months ago, in my heritage country Australia" Emerald started.

-Flashback 3 months ago (Emeralds pov)-

It started the same way it started here, only I ran straight for the gates, I didn't need a car because I only lived a couple of kilometres down the road, when I got there I saw my family fighting a large group of Them, my father ordered me to run, but I insisted on fighting. By the end of it I was the only one who wasn't bitten, and one by one they turned, with my dad coming in last telling me to set them free from this life of endless hunger he asked me to kill them as he was starting to turn, but I couldn't do it, he knew I couldn't disobey a direct order so he then ordered me to do it, and as much as it pained me to do it, I took my dad's .44 magnum and killed them, I could almost swear that even though he was turned he mouthed the words thank you. I then piled everything from my dad's weapon stash and took his boat here, then there was customs but that's another story.

-End flashback (normal pov)-

"All my guns are in my apartment, but I always keep a knife and my dad's magnum on me, and his golf club that I'm using, my personal weapon of choice (Ok that kind of explains it, but why the school supply closet?)" Emerald said as he took about the three weapons "Now before you ask I didn't use my gun, because any noise that a zombie can hear, is like ringing the dinner bell, as for the knife, that's only a backup" after that Rei started crying again and ran to comfort Emerald who noticed Takashi at the barricade. "TAKASHI" he called as the black haired male started to climb the barricade. Rei than ran over to him and grabbed his arm tightly

"I'm sorry Takashi, I didn't mean anything I said before, just don't leave me" Rei begged as Takashi froze before climbing down and hugging her. Rei then slowly returned the hug as Emerald watched the spectacle infold with a smile.

To be continued.

Hey guys I'm back with another fanfiction and I hope you enjoyed it, it came to me in a dream, the same night I actually watched high school of the dead. Started off as a Vegas style all you can eat buffet that I was invited to then glitches into watching the straw hat crew battling alongside Takashi and his team against Zombies at the high school. I then awoke in a cold sweat thinking 'BEST CROSSOVER EVER' please feel free to leave a review but no flames, or I will burn you to ash.
