(Naruto World)

As Tsunade was currently stacking up all the paperwork that had accumulated after the 4th Great Ninja War, she was interrupted by somebody barging into her office. Of course, even with her back turned she knew exactly who it was.

"What is it this time Naruto?", she asked with an already annoyed look on her face.

Naruto Uzumaki, the hero and savior of the world already had a disappointed look on his face.

"Grandma Tsunade, isn't about time you retired and let me take over as Hoka-

He was immediately interrupted by a punch upside the head, courtesy of his teammate Sakura.

"Idiot, how many times have I told you not to barge in and disrupt Lady Tsunade while she's working", Sakura yelled angrily while raising her fist.

"Now now Sakura, Naruto is just being enthusiastic", said a calm voice just behind Sakura. She turned around to see her Sensei Kakashi Hatake, with his eyes buried into one of his books.

"Not you too Kakashi-sensei," Sakura said with an exasperated look on her face.

As Naruto was nursing his headwound he couldn't help but notice that something felt odd. His suspicions were immediately confirmed when a short blue man, with slicked back gray hair appeared floating directly above the sealing.

"Greetings you all", the Grand Priest said with a small smile on his face. However, his smile was meet with every ninja in the room drawing a kunai and watching him cautiously.

Tsunade then stood up while watching him with narrowed eyes, "Who are you?" she asked angrily. "And why have you infiltrated the Leaf Village?"

"Infiltrate?", questioned The Grand Priest. "You misunderstand my intentions, I am here to invite you all to a grand occasion. A tournament unlike any your universe has ever seen."

Kakashi, Tsunade, and Sakura were all puzzled by the fact that this stranger just appeared, asking them to participate in a tournament. Unfortunately, there was someone who was quite vocal about his objections.

"And why the hell do we have to do what you say?", Naruto asked with an angry look on his face. "You can't just barge in here telling us what we can and can't do. Who do you think you are?"

"Yes, I agree with Naruto", Tsunade stated with a now calm, yet cautious look on her face. "What happens if we refuse to join your tournament?'

At this, the Grand Priests smile started to waver, before he had a disappointed look on his face. "Should you refuse to enter the tournament, it will be taken as a disqualification at which point your entire universe and everyone in it will be erased".

Not a moment after this declaration Tsunade and Kakashi both already had a kunai to the neck of the Grand Priest, with a serious expression on the face, and eyes of them both.

"Is this really necessary?", Grand Priest asked with a still calm look on his face.

"You barge into my village unannounced, appear into my office without warning, then prepare to threaten us all with death if we don't comply? I think these actions are very necessary", Tsunade stated angrily, never batting an eye.

The Grand Priest only sighed before releasing a burst of ki strong enough to send Kakashi and Tsunade up against the wall.

"Well, now that we have that matter settled perhaps we can reach a form of understan-"

"Rasengan". The Grand Priest turned to see the cause of the disruption only to immediately get hit in the face with a large ball of energy. However, Naruto was shocked to see that the attack had absolutely no affect. He quickly jumped back before pulling out another kunai.

"Just who the hell Is this guy? He took my Rasengan like it was nothing. What exactly are we up against?", Naruto thought with some confusion.

"So then," said Grand Priest satisfied that his message had been delivered. "I will see you all tomorrow at the tournament stage, someone will be on the outskirts of the village to take you there".

"And who exactly will we be up against?" Sakura asked confused. "The other villages".

"Oh no, nothing like that. You will be up against the members of 7 other teams from 7 different universes with 10 people for each universe".

This shocked all of them, not only at the revelation of more than one universe, but the fact that they would be competing against these other Universes. However, before they could ask any more questions, The Grand Priest suddenly disappeared without a trace. As Tsunade walked over to get a drink she took a swig from a large bottle before turning to face the others.

"Team 7", she stated with a serious expression on her face. "I want you all to keep this top secret from anyone else except who I give the say so. If this gets out it could cause massive panic". She then turned to Sakura and Kakashi. "I want you two to call the other Kage for an emergency meeting right now, we need to determine who the other 8 competitors will be".

"Other Eight?" Naruto asked confused, "You mean you already have two?"

"Of Course, you will be participating Naruto, we can't have one of the saviors of the world stand aside for such an important battle".

At this Naruto nodded with a smug look on his face, before his eyes widened. "Wait, you said one of the saviors. Does that mean that-"

At this Tsunade gave a small smile as well, "Yes Naruto, I am going need you to get a hold of Sasuke."

(Bleach World)

Shunsui Kyoraku was currently napping enjoying the peace that was brought with the defeat of Yhwach. However, his sleep was disturbed by the sudden opening of his door, he looked up surprised to see his Lieutenant Nanao, with a nervous look on her face.

"Captain Kyoraku, we have a serious problem", she said with a hint of fear in her voice.

"What's the problem my precious Nanao?" Shunsui asked with a calm smile. "Or did you come to have a drink with your captain".

Shunsui's smile quickly dissipated however, when he noticed that she didn't react in the usual manner to him. Rather, she continued that same fearful look on his face.

"What's wrong?" he asked with a serious look on his face. Wondering himself what caused Nanao so much trouble.

"There is an intruder that just appeared in the middle of the Soul Society, by the 6th Division. Captains Kuchiki, Hitsugaya, and Soifon all engaged the intruder, however-" she began before she started trailing off.

"What happened?" asked Shunsui with concern.

(6TH Division)

"This is impossible", stated a random soul reaper.

"There is just no way this is happening", another said in denial.

The image before all the other soul reapers was indeed a sight to behold. All three of the Captains had engaged this mysterious assailant, and all three were on the ground.

"Now will you finally listen to what I have to say?" asked the Grand Priest.

"Gokei", said Byakuya calmly as millions of blades from his bankai surrounded the Grand Priest in a dome. However, as the blades began to converge on the intruder they were all suddenly blasted back by an unusual energy.

"I told you, I am not here to fight any of you", the Grand Priest said beginning to appear annoyed.

"Sennen Hyoro," stated Hitsugaya as severly pillars of ice emerged around Grand Priest and smashed into him. As his bankai wings began to melt he suddenly noticed a presence behind him, before he turned around and was finger flicked on the forehead, sending him flying through several buildings.

As Byakuya and Soifon got up to attack him again, with Soifon preparing to attack again, this time with her bankai. They suddenly stopped with the appearance of Shunsui already having drawn his swords.

"Hello there", Shunsui said with a calm, almost casual smile. "What brings you to sole society this fine morning?"

"Are you the one in charge?" asked The Grand Priest with a restored smile back on his face.

Shunsui merely smiled back at him, "Why yes indeed, I am Captain Commander Shunsui Kyoraku. And who might you be?"

"They call me the Grand Priest, and I am actually here to invite you to a tournament".

"A tournament huh?" asked Shunsui while scratching his goatee. "That's interesting, however I will have to decline this tournament, for the simple fact that we recently have been recovering from war."

At this The Grand Priest began chuckling, "You are not the first universe to say that to me, however, I believe that I should tell you of the consequences of not participating."

"And what exactly will those consequences be?" asked Shunsui, while at the same time never taking his hand off the hilt of one of his blades.

"Your universe as well as all of its inhabitants will be erased immediately".

This revelation finally brought a look of shock to the face of Shunsui, as well as every other soul reaper present.

"Universal Destruction?", repeated Hitsugaya in awe.

"It can't be, another monstrous threat like Yhwach?" asked Soifon with a trace amount of fear in her voice.

"Do you honestly believe that we would sit back and allow our universe to be taken away?" asked Byakuya with a slight twinge of anger beneath his calm exposure. "We have dealt with someone like you before".

"No no no, you misunderstand me", The Grand Priest calmly said. Almost as if he was talking to children. "The one who will do the erasing is the Omni-King. And trust me when I say that I am nothing compared to his power".

This revealation not only shocked the persons present. It also involuntarily sent a shudder of fear down all their collective spines. After all, here was the man who easily brushed aside three captains, two of which were using bankai. Yet he claims that this Omni-King is far superior to him?

Of course, what no one could have anticipated, was the sighing of Shunsui before he turned towards the Grand Priest. "Very well", he almost yawned out, his sleepiness starting to catch up with him. "If the Omni-King says it must be done, then we will join your tournament."

While the Captains present, as well as Nanao looked at him with shock, the Grand Priest simply smiled and nodded before he began to glow with white light.

"Very well then, somebody will be here tomorrow to pick up your 10 chosen. I shall see you all shortly", he said before waving with a large smile as he vanished.

However, the minute he did Captain Soifon approached Shunsui with a look of anger, "Did you seriously just let that man get away? After harming several captains as well as Soul reapers.

"Look Soifon-"

"Not only that he threatened all of us, and yet you still let him get away".

"Listen Soifon I-"

"Is this what being Captain Commander is too you? Being complacent and showing your belly every time there is a threat of-"

"ENOUGH SOIFON", yelled Shunsui angrily while releasing a burst of his spiritual pressure, immediately silencing Soifon. After calming down he looked at her before deciding to explain.

"Many many centuries ago, the Soul King was told along with his Royal Guard, about the existence of the Omni-King as an absolute existence. Surpassing even the Soul King itself. This knowledge was to be passed on to the Captain Commander, as well as the members of Central 46.

This new information stunned everyone within earshot to silence.

"So that is why I agreed, because I know that if we were to disobey then our Universe surely will be erased by the Omni-King".

With this shocking information, Soifon was both embarrassed and ashamed for snapping at Shunsui. However, she was saved from making an apology, that she would surely regret, by the stepping up of Byakuya.

"So, what will you do now that we are facing this threat?" asked Byakuya curious about Shunsui's next move.

"Well first I am going to go home, finish my nap, then find 10 members to participate when I wake up", he stated calmly before walking away. This action caused everybody in the vicinity to sweatdrop, as well as well as some of the no name soul reapers to start freaking out.

"There is no denying it now", stated Hitsugaya as he watched Shunsui walk back to the direction of his barracks. "Soul Society is doomed".

(Meanwhile)

The Grand Priest continued this process with the other 6 universes, deciding to talk to their worlds respective leaders from the beginning, to minimalize the possibility to combat.

He talked to the Gorosei of the One Piece World, along with the Yonko and Dragon; he talked to all the leaders of the Mafia family, including the Vongola of the Hitman Reborn World; He traveled to the world of Fairy Tail and talked to King Fiore, as well as the Kingdom of Liones of the Seven Deadly Sins world to speak with their king; Although there was some disbelief, he managed to convice the members of the Hunter's Association in the Hunter x Hunter World, and King Enma of the Yu Yu Hakusho World.

When he reappeared in front of the Omni-Kings they both began jumping up with excitement.

"So so, how did it go?" asked Zeno-1

"Yeah, yeah how did it go?" Zeno-2 asked with the same expression on his face.

"It went incredibly well", stated The Grand Priest with the same smile on his face. "Although some of the universes proved difficult, never the less, all of them will have 10 warriors ready for your tournament tomorrow".

"Awesome Awesome", yelled both of the Omni-Kings simultaneously. "This is gonna be so much fun".

As both childish deities prepared for the universes battle. The universes themselves were preparing for a tournament that could mean the destruction of their own universe, however none of them could be ready for the opponents that they would face.

Coming Up:

All the different universes begin gathering the 10 people they will need for the tournament. With some even bringing along some unexpected fighters.
