John and Nesiara weren't looking really fresh like the others who passed their trials when Tsuna asks, "What happened to you two?"
"Training. A lot of training," says John as he felt exhausted after leaving the White Space almost falling over when Jack catches him.
"Right the side-effect is kicking in," says Jack as he puts his hand against John and uses healing magic to heal him up before taking a bean out of his pocket and gives it to him before turning to Nesiara that was standing because she was using her staff. He then heals her before giving her a bean too.
"Why was I feeling this weak?" asks Nesiara confused since she felt so energetic a second ago.
"It's the side-effect of the White Space. You will always feel energized so you can keep training without resting. That's why you never needed to eat or sleep while inside. I'm already accustomed to it as well as Kara and Zeus," says Jack explaining why they felt so weak as he walked over to Fang and Jinx to heal them up before the others suddenly turned into white smoke making them known that they went back into the future.
"Time for you all to leave again," says Jack as he opens a portal and sends the remaining six through the portal as they arrive at the same courtyard.
"It doesn't seem as something happened while we were gone," says John as he looked around and they found Shoichi as well as the blond guy as they were sitting exhausted in the courtyard when the group arrived.
"You are back. I had to make a deal with Byakuran. We will have a show-off against him in a week. It will be a fight between one side against the other. I wanted to make it a Choice Game but Jack said that it would be easier to have you fight in a battle royal until only one side stands," says Shoichi as Jack appears beside them.
"That's right. I thought it would be the fastest way to resolve this problem," says Jack as he walks over to them and says, "Now you all need to pass the last trial before fighting against Byakuran."
Jack was suddenly surrounded by his armor as his spear appears in his hand and he releases a little bit of his aura that made everyone shake in fear as a giant monkey face appeared behind Jack.
"You need to fight me while I only use 0.001 percent of my power. I want to see if you are strong enough to fight against Byakuran or if I'm sending you to the chopping block," says Jack seriously as he opened his third eyes intimidating them.
"Come at me with everything you have," says Jack as he gets in position holding his spear while pointing it towards the ground.
The other prepare for this last trial even Uni was ready to fight and Jack says, "Fight."
The trial began as Jack disappeared from their sights and three Jack's appeared between the group as the Jack's attacked at the same time making everyone be on guard. The first Jack attacked Tsuna, Gokudera, Takeshi and Ryohei. The second attacked Mukuro, Chrome, M.M., Chikusa, and Ken. The last attacked John, Nesiara, Lancia, Hibari, and Uni.
POV First Jack
The attacks of the first went through Tsuna as if it wasn't real until the spear was about to hit Gokudera who thought the same would happen to him when the attack made contact with Gokudera.
"It isn't an easy trial so give me your best," says Jack as he sent Gokudera flying towards the courtyard wall. As Tsuna attacked and his attack went through Jack as he fell through Jack as if he wasn't there in the first place.
Ryohei joined Tsuna while Takeshi was helping Gokudera before joining the fight again. The fight went on until they slowly trusted their instincts when an attack was real or fake. They evaded the real attacks while ignored the fake ones.
That went on until Tsuna got a successful hit onto Jack who hit the pommel of the spear against the ground making the ground shake for the four the first Jack was testing.
"You got the trick after fighting me for a while. Good you four pass," says Jack as he disappears before the four hear, "Sometimes the attack of your enemies will be like mine. It will look real but it is fake and sometimes it will look like a fake but it will turn real all of a sudden."
POV Second Jack
Mukuro and Chrome were tracing an almost too fast for them Jack who appeared and disappeared all of a sudden attacking them from behind.
"Sometimes you can't face your enemy alone as you all use to do. Sometimes you need to work together," says Jack as the group was now back to back so Jack couldn't attack them.
"What do we do he is too fast for us?" asks Chikusa as he couldn't keep up with Jack's speed.
"We just need to stop him somehow," says Mukuro as Jack appeared in front of the five.
Jack split up in five more Jack that began to run circles around them making it impossible for the normal eye to follow him.
"Chrome can you try to track him with your left eye?" asks Mukuro as Chrome's left eye turned into a Sharingan and she dragged Jack down as he wasn't even running around them but only illusions were.
Jack was standing some meters away from them as Chrome tells them what she found out and they begin to advance towards Jack's position trying to get him.
"All at once or we won't get him," says Mukuro as Chrome stops them.
"I think he is waiting for us to attack him," says Chrome as she was feeling something is odd with Jack just standing there waiting for them.
"What do we do then?" asks Ken as he was ready to attack on Mukuro's command like the other two too.
"He said we need to fight him," says M.M. as she wanted to attack while they still could.
"Yes, but he never said how to fight him," says Chrome as Mukuro was split in two.
One half wanted to attack while the other wanted to listen to Chrome. Then Mukuro began to think and found out that Jack never attacked first but always countered them.
"He doesn't want to fight us," says Mukuro after analyzing Jack as he walked closer to Jack but didn't attack.
Then Jack hit the pommel of the spear against the ground and says, "Sometimes you need to trust your people when you don't see the whole picture. If you can't do that you won't live long enough becoming a lone wolf that doesn't trust anyone except himself. I hope that never happens to you."
Jack then vanished from their eyes while saying, "You passed my trial."
POV Third Jack
Nesiara, John, Lancia, Uni, and Hibari were working together to get the last Jack down.
But to their disappointment, it wasn't that easy. Jack always somehow deflected their attack as if it was easy like he was a stone in a current that didn't move.
"You all are strong but you are all still missing something," says Jack as he deflects Hibari's attack and sent it towards Lancia before attacking John and sending him towards Nesiara. Then he turned to Uni who attacked him as he deflects her attack and sends her towards Hibari.
Hibari gets hit on the back by Uni's attack as Jack was standing there and says, "The one that is calm at any moment can fight heaven. The man that can be calm while being angry can defeat it. Show me your will in wanting to defeat me."
They continue to fight Jack until they found out what this Jack flaw was. They were all strong but not flexible enough to adapt to their opponent. They only wanted to defeat their opponent but never thought that their opponent could make them their own enemy by making them attack each other by deflecting their attacks.
Once they adapted this Jack did the same as the other two before saying, "You all need flexibility. Being strong is good but being able to manipulate your enemy's attack is better. You still have many holes that need to be fixed. But for now, I have only something to say "Be like a stone in a river. Immoveable." Once you become immoveable no power be it small or big will move you since you can always deflect the attacks and make the enemies attack themselves."
Jack slowly vanished as he says, "Remember it. It might save your life one day."
The real Jack, who was sitting on the roof of the house, says, "It seems you all passed the trial after some hours. You should rest and train in less than a week you will be fighting against Byakuran and his Wraths."
The people were preparing for it when Shoichi brought some suits out that he made for everyone. They put them on and John says, "It looks like we are going to a funeral wearing this."
"It's something like that," says Nesiara as she smiled while walking in front of him.
"I will have to fight seriously then," says John as he walked behind everyone.
As they arrive at the meeting point where everyone was waiting.
"Now that everyone is here we can begin, can't we? Uni you are on my side aren't you?" says Byakuran as he was eying Uni since only she could control the Tri-Ni-Sette.
"I would prefer to stand where I'm," says Uni with courage.
"So you betrayed me too. Well I can begin it in another world then," says Byakuran as he looks around and asks, "Now shall we introduce the judge for this battle."
Two Cervellos appear when Jack appears and says, "Nah they won't be the judges in this battle."
He walks on the battlefield as he created it and says, "The judge will be someone far older than all of you together. He is the Guardian of the Tri-Ni-Sette. Reborn as well as the other Acrobalenos know him better as Checker Face."
The battlefield was formed as the battlefield had every element in it making it easy to fight in it. People on the Millefiore Famiglia was now a bit split since Uni wasn't in it any longer.
Reborn on the other hand was pale hearing that the man who made him a toddler would be the judge in this battle between the Millefiore Famiglia and the Vongola Famiglia.
Kawahira appeared in his Checker Face outfit as he walks over saying, "Now then, are all contestants ready since the battle will begin soon.
Reborn was pointing his gun at Kawahira as Mirch did the same with her shotgun.
"Now is not the best time to fight me. Anyway, you already won against me in the past. You just don't know it. Well it wasn't in this timeline after all," says Kawahira as Reborn and Mirch put their guns down.
"Now then let this battle begin," says Kawahira as Jack snaps his finger and everyone was sent randomly to a part of the battlefield.
"Who do you think will win?" asks Jack with a mocking smile.
"You really have to ask that. It's pretty obvious who will win aren't I right," says Kawahira as two people appeared behind them. One was a giant as tall as Jack who was carrying a two-hander and a katana while the other was a refined woman carrying a staff when Kawahira says, "Nesiara and John."
"We were just around to see how everything is going since we got a message to return from Hibari but it seems we came for nothing. This future should also soon be destroyed," says future Nesiara as John nods.
"It will be fun to see our past selves. After all they are walking another path than we do," says John as he looked at his past self and sees that he had a different style of fighting than himself as he says, "I really want to fight myself but I will seize to exist once this is over."
"Too bad right. I really want to know from where my past self got that spear," says Nesiara looking at Jack.
"I don't know since I will also seize to exist once this is over. It was fun to see them pass my little test but it will even more fun for my past self to see them achieve great thing like you two did," says Jack with a smile as he was looking at them.
