Another World Ends With You

A/N: This story is a crossover between Harry Potter and one of my favorite games, The World Ends With You. Because TWEWY is a short game that spans over the course of only a month, it's really hard to ignore spoilers or to even make it canon-compliant with this story. But I'm going to try my best. If you've never played TWEWY (and I'm assuming most of you have never heard of it) and if you want to play it later, then read this story with a wary eye. It may have spoilers. If you don't care about TWEWY, feel free.

By the way, I have no idea whether Harry would know what a cell phone is. He most likely wouldn't have one but he needs to have one to make this work. Because I don't know British slang or anything like that, I won't give that too much attention.

Eh, one more thing before this story gets started. I'm going to use some actual dialogue, or at least dialogue that is very close to the actual dialogue in TWEWY. This is my first story with TWEWY characters, and considering the circumstances I have to make the characters say something close to what they said in the game.

Chapter 1: Shibuya

Harry lay facedown on the pavement, disoriented and unaware of his environment. His head was throbbing with a headache, which was made even worse by the loud chattering surrounding him. A chiming noise sounded and was soon followed by footsteps.

Several long minutes had passed before Harry was able to push himself off the ground. Wearily, he surveyed his surroundings only to find that nothing around him was familiar. Wherever he was, it was definitely not part of Britain.

More importantly, what was he doing in that particular place? The last thing he remembered was … well, nothing. Harry couldn't remember anything other than his name and that he was from Britain. He also had a nagging feeling in the back of his mind that there was somewhere important that he had to be at that moment … but he couldn't remember what.

Once more, he chanced a glance at the people and places around him. He was standing in the middle of a busy intersection, people walking in every direction and minding their own business. In the distance there was a multistory building with the numbers 104 emblazoned on the side so that everyone could see.

Again, Harry wondered where he was. He felt out of place amongst the crowd walking past him. Not only were they dressed differently from him – trendy brand clothing from popular designers compared to his black robes – but they all looked different too. Every person on the street was Asian. Harry assumed that he had been transported to some city in Asia … but why?

First things first – he would have to figure out where he was. Harry approached a teenager who was walking in his direction. "Excuse me – " He made to tap the guy on the shoulder, but much to his shock his hand went straight through.

Drawing back as if he were electrocuted, Harry looked down at his hand, mouth agape and speechless. The bystander he had tried to talk to continued on his way as if nothing had happened.

"What the …"

Harry's mind was racing with a million questions and thoughts. What had just happened? Why did his hand go through that other person's body? Why was it that the people around were ignoring him? What had happened to him prior to waking up in the intersection?

A beeping noise from his robes brought him out of his thoughts. Fumbling through the pocket, he pulled out a strange rectangular device, red and folded once over. Flipping it open, he found a message printed on the screen: 1 NEW TEXT MESSAGE.

"Err …" Harry scratched the back of his head. "What's this?" He pressed a few buttons on the device, trying to make it work, and with time a new message popped onto the screen: Round 1. Reach 104. Game over will result in erasure.

Suddenly, a sharp jolt of pain surged through his hand. Harry gritted his teeth and looked down to see what had happened.

Much to his horror, what he saw was a timer burned into the palm of his left hand. A timer outlined in red counting down numbers, numbers that had previously read 60:00.

For a moment, Harry could do nothing more than stand frozen in place, staring at down at his hand. Then, angrily, he let out a shout. "What is going on here?"

Not even a second later, static filled the air and several red graffiti-looking symbols floated into sight. The countdown on his hand momentarily forgotten, Harry involuntarily reached into his other pocket and pulled out a long stick. Too alarmed by the appearance of the symbols, Harry didn't even pause to wonder why he had the stick or how he knew what to do with it. Muttering a string of words under his breath, he pointed the stick at the symbols, but nothing happened.

Emerging from one of the smaller symbols was a green frog creature that hopped towards Harry and attacked him. Once again, Harry attempted to retaliate with his stick, again to no avail.

"There's nothing I can do," Harry muttered, clutching his arm. As much as he hated running away from his problems, there was nothing he could do to fight back. "I have to get out of here."

With that thought in mind, Harry fled the intersection – the frogs close behind him.

-

"How troublesome. We're supposed to work during this week too?" said a redheaded man with a lollipop.

"Oh, quit whining," snapped a pink-haired woman, but her voice was less sharp than it was playful. "Now's our chance to rack up some more points! … Still, I have to admit, it is weird for the Game to be run this week."

"Two weeks in a row, hm?" the man sighed, but then chuckled. "It's unusual all right, but not completely unheard of."

"They've done this before?" asked the woman. "What for?"

"Details, details." The man stuck the lollipop in his mouth casually. "All right, let's do this."

-

Meanwhile, Harry had arrived at a different part of the city. The most noticeable feature was a large statue of a dog in the center of that particular area. Harry didn't have much time to rest, however, for the frogs had already caught up with him.

"I'm sick of this," he growled. "What am I supposed to do?"

The sound of screaming reached Harry's ears just then. He spun around in the direction the voices were coming from, stick drawn, determined to do whatever he could to help. The red graffiti symbols that had been chasing him floated towards a group of people and clung onto them.

And then, both the people and the symbols disappeared into thin air, as if they were never there in the first place.

"W-what …" Harry was horrified. "What happened to all those people? Why am I even here?"

"Hey! Anyone!" came an accented voice from somewhere within the area. "Holler back if you haven't made a pact!"

"Huh?" Harry whirled around to find a teenager with spiky red hair and oversized blue headphones running towards him. He was also being followed by frogs. "Behind you! Look out!"

"You!" The kid with headphones took one glance at Harry and yelled, "You're a Player, aren't you? Form a pact with me!"

"A … a pact?" Harry repeated, utterly confused.

"Hurry up! Do you want to be erased? We can't fight the noise until we form a pact!"

Harry had absolutely no idea what the kid was talking about, but he seemed to have an idea what was going on, something that Harry did not. He was also frustrated enough to do anything to get rid of the frogs that were trying to attack him. "Yeah, sure, let's do it."

As soon as the words had left his mouth, Harry and the teen with the headphones were surrounded by a glow of white light. Then, as soon as it had appeared, the light vanished.

"Whoa!" Harry blinked, surprised. The day seemed to be full of nothing but surprises.

"All right," the headphone boy said, glaring at the frogs. "Time to finish this."

Once again, a burst of light blinded Harry, but when the brightness cleared away Harry saw that he was standing alone, in front of the statue of the dog, and that the frogs were staring him down, ready for a fight.

"Hey, where'd that kid go?" Harry thought out loud, taking a quick look around. His attention soon returned to the frogs, as one lunged at him in a tackle. Almost instinctively, Harry raised the stick in his hand and shouted, "Stupefy!"

The frog reeled back, obviously hurt from the red jet of light. The other two frogs made to attack Harry as well, but the bespectacled teen simply fired a spell, knocking them back. One of the frogs disappeared in a flash of static when the spell hit it, a second one soon to follow. The third one, on the other hand, mysteriously vanished without warning.

And when the battle was over, the crowds and people were back. The spiky-haired kid who had called out to him was back as well, looking annoyed.

"That took more time that it should've," he grumbled. "Well, there's no use hanging around here anymore. Let's go. 104's the other way."

"Hold it," Harry said. His temper was finally starting to give way. The day had been nothing but unexpected, and who was this kid to tell him what to do? Harry wanted answers, and he wanted them now. "What's going on? Where is this place? And why am I here?"

"You don't know?" The response was not scornful, nor sympathetic. It was more of a statement than a question.

"No, I don't." Harry was barely able to keep his anger in check. "If you know what's going on here, then tell me!"

"We can talk later," the other teen said, his exasperation and impatience becoming evident. "You got that message, didn't you?" He looked down at his hand. "We have less than twenty minutes left."

Harry noticed the numbers ticking down on the other boy's palm, and glanced down at his own. Sure enough, the numbers now read 17:35, whereas they had been 59:40 the last time he had looked. He hated being left out of the loop, being the only one who didn't know what was going on, but the message he had received said that if he didn't reach the 104 – whatever it was – before the timer ticked out, then he would face erasure. Whatever erasure was, Harry know it wouldn't be anything good.

"Fine." Harry frowned. "But after we get to this 104, you're telling me everything." He paused for a moment. "Anyway, I'm Harry Potter. You are?"

The other teen was silent for a moment, then he said, "Neku. Neku Sakuraba."

"Neku?" Harry made a face. "Weird name."

"Agh!" A strangled sound escaped from Neku's throat. "Let's just get going!"

"All right, let's move," Harry said.

-

Harry and Neku made their way back to the intersection about five minutes later. Harry had no idea where to go, but Neku seemed to know the layout of the city very well. He headed north and approached a guy with a red hooded sweatshirt and bat wings sticking out of his back.

"Want past this wall?" the winged guy asked. "Then defeat the noise."

"Noise?" Harry asked. "What are noise?"

"They're those things that we just fought," Neku answered, his voice unable to mask the frustration he was feeling. "You ready to fight again?"

"Oh, sure."

Once again, Harry was pulled into an alternate plane that had no people or obstacles around, only the background and the enemies he had to fight. He was facing against not only frogs in that fight but also two ravens.

Again, Harry fired spells from his stick at the frogs and ravens. With five enemies against him at the same time, however, Harry was attacked a few times from behind. The other boy – Neku – was nowhere in sight, but two of the frogs and one of the ravens burst into static and were defeated even without Harry having to attack them. The battle ended when Harry felled the second raven with a Stupefy spell.

"That was … strange." Harry was starting to wonder how he was able to cast spells with the stick he had, and why he had the stick in the first place.

"Objective complete," said the hooded man. "Wall clear!"

A low sound filled the air, so low that had it been any softer or the crowds any louder Harry would've missed it. Neku, unperturbed by the any of it, continued on his way. He was heading for the building that Harry had spotted in the intersection, the one with the numbers – 104! So the 104 was a place, a building to be specific. Harry went after Neku. The sooner they reached their destination, the sooner he could find out what was happening.

Neku stopped in front of the large white building. He glanced down at his hand and sighed. "Timer's gone. Looks like we completed our mission."

Harry did the same and was relieved to find that the numbers really were gone. "That was odd. But it's all over." He let out a sigh.

"Over?" Neku glared at him. "What are you talking about? This is not over yet. We've still got six more days before it's over. And I can't afford any screw-ups. I can't afford to lose. Not now."

"What are you talking about?" Harry snapped, his temper finally boiling over. "And where are we anyway? I don't understand what's going on. I just woke up in the middle of that intersection we just left and it's been one thing after another. And I've had it! Start talking. Now!"

"You really don't remember anything?" Neku asked once again, his anger dimming down to exasperation. "Not even where you are?"

"No! This looks nothing like Britain!"

"Britain? Is this a joke?" Neku clenched his fist, looking mad enough to hit Harry. "You're in Shibuya!"

"Shibuya?" The pronunciation of the word felt unusual on Harry's tongue. "Where …?"

"That's right, we're in Shibuya," Neku said, still looking frustrated. "You're nowhere near Britain. And you know why you're here? You're here for the same reason as me, as all of us."

A/N: And here's the end of the first chapter. If you've never played TWEWY, you're most likely just as confused as Harry is. Don't worry, everything will be explained in the next chapter or two. And that's being nice. The game itself doesn't reveal why Neku is in the Game until the fifth day.
