'Alright in that case I will be summoning tobirama senju!.' stated Levi.

He decided to start with someone like Tobirama as he was a safe option, he really wanted to summon Madara as he was a big fan of him but even with the system's reassurance that he would be completely loyal, he couldn't be at ease.

'The system said that the people I summon will be completely loyal to me, but this is Madara we're talking about, he even broke out of edo tensei what says that he can't find a loophole, I can't take that risk, at least not for now.' he thought, he needed to at least be able to handle him if he went rogue.

'Tobirama on the other hand although was still a risk he had a lower chance of killing me if something goes wrong and an even lower chance of bringing havoc on the world.'

'System I want to summon Tobirama Senju in his peak form, his memories from the timeline after he was released from the edo tensi, post the fourth great ninja war. As for the background. Hmmmm let's see,' Levi didn't know what background would be best to give him.

He thought of making him a refugee who drifted to the chores of the southern water tribe one day before being rescued by them and so he ended up in their debt and chose to stay around, but it didn't fit what he wanted exactly, plus why put a limitation on him making by making him an outsider when that wasn't necessary.

So after a lot of thought he came up with the perfect background that suited his tastes, 'For the background, Tobirama will be a member of the Southern water tribe, he has a house near the periphery of the tribe and is quite liked by all the tribe members. His parents were killed by the fire nation and he joined the guards right after that, he is a renowned water-bending master who awakened his bending at the young age of 10.'

'This should do.' After he was done with the background customization he summoned his character.

As he waited for the second Hokage to suddenly materialize in front of him like magic he thought about how crazy all of this was, being reincarnated with a system was unbelievable enough but now he was bringing in other people from other worlds or maybe even universes? Sometimes he really wondered where the system came from but seeing that he could never come up with an answer he let it be.

Quickly something started to materialise in front of him but it wasn't what he had expected, instead, it was a system notification.

[To customize the character background the user needs to spend an extra character summoning card or consume 5000 system points.] 

'Hmmm will different characters I summon consume different amounts of system points?' asked Levi in his head, he suddenly wondered how much it would have cost him if he didn't have summoning cards.

[That's right user ] 

'I see how much would Tobirama cost if I had used system points instead of summoning cards.'

[100.000 system points]

'That much?.' Levi was shocked, he expected it to be a lot considering who he was bringing over but he didn't think it would be that expensive. 

But on second thought it was only fitting, Tobirama was the second god of shinobi, and if he weren't limited by this world power level he could literally destroy it on his own, 'In fact I believe he could still swoop through this world with high difficulty even after being limited.'

Seeing how valuable the character summoning cards were compared to system points, Levi decided not to waste them on something as trivial as background customization and instead save them for some special cases, confirming his choice Levi waited while holding his breath.

A spot of light appeared in front of him giving off very dim lighting before expanding till it was the size of a human being. 

Thankfully no light slipped out of the room, slowly the ball of light started contracting back into itself before collapsing into the shape of a human, it was vague at first and it had no facial features or any distinguishing characteristics but slowly it started to take form. 

A 182 cm (6ft) white-haired man that appeared to be about 25 yo and with a serious expression appeared in front of Levi, he was wearing the standard Southern water tribe clothes and there wasn't anything particularly noticeable about him except his above average looks and white hair. 

Finally the figure of Tobirama was done materializing as he opened his eyes, revealing a bright red color, but one thing seemed wrong, it was like he wasn't fully aware yet.

'It's ironic that he hated the uchiha but he's cursed with the same eye color as them, I bet it kept him awake at night hehehe.' thought Levi after noticing Tobirama's eye color.

*****

Tobirama pov.

Slowly but surely life seemed to return to Tobirama's eyes as he observed his surroundings with a frown, all he could see was a simple room and a child of about 8 years old standing in front of him looking him up and down. 

The last thing he remembered was getting released from the Edo Tensei after having helped win the fourth shinobi war the next moment he was here.

Looking down at his hands he couldn't hold his shock at what he saw, he wasn't looking at the fake skin of the edo tensei but at real flesh and blood, 'What is this? it isn't impure world resurrection, it is much much different, it's on par with the Rinnegan resurrection, this is unbelievable, and I am in another world?.' he thought processing the new memories in his mind not able to wrap his head around it.

'I also have memories that correspond to this world, I have just been summoned but I already have memories of all the people in the Southern Water Tribe, this world, the power system, the ruling powers, and so much more? if that was all then it wasn't that big of a deal but they also have memories of me, and for a long time now, I am part of them?

This isn't just some random genjutsu, this is on the level of bending reality, just who is this kid?

All of those thoughts ran through Tobirama's head in barely a second as he looked at Levi before finally getting down on one knee and uttering, "Master am at your service."

He didn't feel anything weird saying that even though it was the opposite of his personality, actually, it felt quite natural, a being who could summon him all the way from another world and bend reality, who else was worthy of being a master other than a person like that, he didn't know if it was this "being" power that was changing his thoughts and making him think that or it was all him but he didn't care.

Levi pov 

He nodded as he saw Tobirama kneeling before him and said "Get up, you don't have to kneel and call me master from now on. I don't want to cause a misunderstanding, plus it's a little awkward."

"You already have a complete understanding of your situation right? " asked Levi probing Tobirama for information, the system already told him that the characters would have complete knowledge of their situation and their background if he gave them one coupled with complete loyalty to him but it wouldn't hurt if he checked. 

"Yes I do, Am totally aware of my current situation." Said Tobirama with a serious voice and stayed quiet after that but it was obvious he was hesitating about saying something. 

"What is it, speak your mind." said Levi after seeing his hesitation. 

"Thank you, if I may inquire, what technique did you just use to summon me? I am fascinated by it." Said Tobirama with a curious expression.

'Oh, I guess this isn't too surprising,' thought Levi as he remembered something about Tobirama from the show. He was renowned for being a researcher and a genius in Naruto, he was also responsible for creating insane jutsus, each one crazier than the last, like the shadow clone jutsu, the flying thunder god and the reanimation technique, so it made sense for him to ask something like that.

Levi didn't know how to answer that question, he couldn't possibly reveal the existence of the system, but he also didn't want to just outright lie, especially to someone whose part of his job was to detect lies, so after deliberating over it for a while he decided to tell him half-truths, "It's a power that I just recently created and tested, you're my first summon actually and I see that it worked splendidly." 

Tobirama eyes twitched as he heard Levi's answer, he already had the memories of this world integrated into him and he knew the limits of this world, if just a normal chunin from the shinobi world was dropped here he could rule the place, and this boy in front of him created such a crazy technique in a place like this? Where only bending powers were supposed to exist.

Tobirama wanted to ask him how he did that but he decided that it wasn't the wisest choice, who in their right mind would openly discuss a technique like that with anyone after having most likely spent a massive amount of time and effort to come up with it, he was lucky enough that he revealed its existence to him.

One thing was for sure though, he was right, this was definitely no normal boy, what he was seeing in front of him was most likely nothing more than an illusion, a splendid one for managing to fool even him but an illusion nonetheless, but then again who was he? In the big scale of things maybe he wasn't even considered a fly.

"Alright you can get up now" said Levi, seeing that Tobirama had no other questions interrupting his train of thought. "So how close are you to your original power level?" he asked, the answer he receives will play a big part in how he proceeds from forward.

Levi had mixed feelings about this, he hoped that Tobirama was as powerful as possible which would make things much easier for him, but he also didn't want a variable that he couldn't control.

Standing straight Tobirama closed his eyes for a while before opening them and saying with a hand on his chin, "I sense no chakra in this world or in my body, instead I feel this so-called chi!, I can move it through my chakra pathway system just fine but it's way less effective than chakra, if I had to make an approximate guess I am at the level of a chunin."

'Chunin? That's not too bad, but wait! He can move Chi through his chakra pathway system? Does that mean he can use jutsus?.', thought Levi coming to a realization.

"When you say that you can move Chi through your chakra pathways does that mean that you can use jutsus from your world here?" asked Levi hoping and almost praying that it was the case.

Tobirama replied while nodding, "I could but I might be limited to only B rank jutsus at most."

Hearing his answer Levi couldn't stop a smile from creeping into his face, that was exactly what he was hoping for, B rank or not it was a blessing in disguise.
