Long ago, the old gods agreed that every universe should be kept separate, as if any of them were to cross paths, the outcome would be severe. However as time went by the gods became bored with their respective universe and they all gathered. They agreed to place a trial; if the inhabitants of three universes could work together and capture an enemy so powerful even Lord Bills couldn't defeat it alone. They gathered three warriors: Son Goku, Monkey D. Luffy and Toriko to defeat the beast and observe if they developed bonds between each other. Naturally after the experiment they wiped the participants' minds because if they remembered the consequences would be severe. Nevertheless the gods agreed to interlink their universes to one world, but they decided it'd be best to make it impossible for people to go anywhere but this world and their original. They decided to utilize a design of a basic town that had schools, cafes, hotels and hospitals. The world was a single city big enough to withstand an infinite amount of people. And so began the saga.
"Aww man I'm bored!" thought Goku, flying along to pass the time. "I wish something exciting would happen. Ever since I fought Lord Bills no one is willing to fight me. Somebody strong needs to show up right know!" Little did Goku know that Luffy was having the exact same thought. As was Toriko. In fact the thought 'I'm bored' was being used by hundreds of others. One such person was Haruhi Suzumiya. "Hey Kyon!" she shouted. "Do we have any new requests?" "I'm sorry but, as always, the inbox is empty" Kyon replied in his usually irritated tone "In fact we haven't had a single request since - Hey, what the? That's weird." "What is it?" Haruhi began to get excited "Well, our inbox just received 5381 requests all inquiring about a strange white sphere that's appeared in the central courtyard." "That's awesome!" Haruhi's eyes widened with excitement. "Yeah I guess, but isn't it a little odd? I mean our school doesn't even have that many students. But each e-mail arrived at the same time, each with different IP's and addresses." Meanwhile, in another universe, Gintoki Sakata had discovered a similar object. But as usual he charged in for no reason other than he was bored. The moment he entered it shut behind him, leaving his friends behind. "Huh? Where am I?" Gintoki walked cautiously around, keeping an eye out for danger. "Welcome Gintoki Sakata" a voice rattled through the air. "You have entered a universal planet, intended for people from separate universes to gather and converse. So far you are the only one to arrive, so I must go and gather others. I will answer your questions when more people arrive." The voice vanished and Gintoki just stood there, offended that the voice dares to leave without explaining anything. Gintoki began to feel bored and in the, what seemed like hours, he grew lonely. However his loneliness was quickly culled by the arrival of several strange figures.
"Hey, you!" One shouted "Do you have any idea what I'm going to do to you for forcing us into this sorry excuse for a planet?" "Vegeta calm down." The second figure seemed to be trying to calm his friend, but Gintoki couldn't hear anything apart from the first figure yelling at him. "Sorry Goku" the third, and arguably the strangest, figure spoke "but for once I agree with Vegeta. That bastard is the only one here so he's clearly the cause." "But Piccolo-" The second figure began protesting. "Leave it dad. Me and Trunks are with Vegeta too. You ready Trunks?" "You know it Goten" "Right. FU-SION-HA!" Two of the figures seemed to move towards each other and merge. "TA-DA! It's Gotenks." The figures finally got to Gintoki. The second was the first to speak. "Sorry about Vegeta, he's a little angry. And Piccolo's not really like that either, he's just thinking logically. As for Gotenks, well he's just excited." "Eh? Sorry I wasn't really paying attention to what you were saying just now." Gintoki was acting half-asleep, despite the fact he clearly heard everything. "Listen to me Kakarot, I'm going to kill this ass and then we can leave" Vegeta yelled furiously. "Vegeta calm down. He could be in the same position as us." Goku was desperately trying to avoid a fight. "Welcome those who have been chosen, to the perfect world." Once again the voice rattled the sky. "What the? Where's this voice coming from? I, Vegeta, Prince of all Saiyans, demand to know where this voice is-" "Oh for god's sake shut up and listen you long haired freak." Gintoki was getting irritated "Let the voice explain everything." "Thank you Gintoki Sakata, but I thought there were more here. I'll explain later." The voice once again left. While all this was happening, Light Yagami and his friend L, were studying a white anomaly. "It's obvious it leads to somewhere" Light stated "But where exactly is impossible to figure out without going through it." "I agree" L said "We'll have to send someone through. Misa, would you mind?" Misa looked at Light and he nodded. Immediately she jumped up and walked through the void. Silence. Then the horrified scream of Misa filled the room and they watched as she disintegrated slowly. Light ran forward to save her but tripped and also fell through. L, being cuffed to him (again), also fell in. Yet nothing happened to them. The only difference was that the cuffs were gone. On the other side they saw the figures of Goku and friends, so they walked over and started talking to them. At the same time people were appearing everywhere. Lelouch Vii Britannia, Kallen and C.C. were among these, as was Luffy, Zorro and Nami. Behind them was Toriko, Itachi and Kakashi. Behind Goku was Haruhi and Kyon. They were followed by Shiina, Rintarou Okabe, Makise Kurisu and Misaka Mikoto. The final people to arrive were Ichigo Kurosaki, Toshiro Hitsugaya, Karin Kurosaki and Rukia and Byakuya Kuchiki. Once they were all gathered the voice spoke for a third time. "Right, third time's the charm. Basically you're all here to just chill and have fun, so in order to do this I'm wiping your minds." "What?" Everyone shouted. "Too late to stop me." As the voice vanished they were all engulfed by a white light that blinded them. One by one they awoke. Something was off though.
