OP and OOC Subaru, and possibly OOC of others characters.

So, what if our boy was one of the most powerful Jujutsu Sorcecers and one fateful day it's transported to Re:zero?

— • —

Natsuki Subaru, a feared name by the Jujutsu Sorcecers, the man loved by the curses and the one with the most powerful Jujutsushiki, a man without any limit, a man who can do the impossible, a man who is buying a promotion of mayonnaise in a minimarket.

"All right, five more mayo for the bunker, who knows when a guy with a scar on his forehead decides to take down humans!" The man with the title of "Strongest Jujutsu Sorcecer" (sharing the place with the prodigy of the six eyes)

"Now what did I have to do...? Oh right, I had to teach Kamo children the new way to apply blood. And teach the gojo child how to use Purple... What laziness..." As Subaru walked away he imagined those scenarios, at first the great clans hated him for "stealing" his techniques, which almost provoked his execution, but thanks to one of the elders he could be postponed to see if he was really useful, thanks to him the clans had increased his repertoire of techniques, being that he was in charge of experimenting, dominating, perfecting and then teaching them, to the point of going on to be hated to be treated as a deity, that bothered him a lot, especially when his house was invaded by possible fiancées of the clans seeking to inherit his Jujutsushiki. T

"Well, let's get back to..." He closed his eyes to the bostezar with a hand in his mouth, but when he opened his eyes again he was surrounded by a completely different scenario. "work...?"

A great variety of people of all kinds passed in front of him... wait, is that a walking dog? Why does that girl have cat ears...? And why the hell did the sun hit so hard! Lucky he brought these glasses with him.

"A Domain Expansion...?" He said in a whisper watching around cautiously.

"Guys are you here?" He said mentally trying to contact his curses, thanks to his eyes, he was a being worshipped by curses, once he found one, he immediately showed his respects and begged him to let him be by his side, which he does not even know very well why, made him develop that kind of father complex, treating curses like children.

" Yes boss, we're here." A dominant voice said, after Subaru asked, hundreds of curses of different types and grades appeared instantly being visible only to him, the one who spoke was a kind of Chinese dragon appeared upon him.

"Well, stay hidden until I say otherwise, I'll check if this is someone's Domain." They all nodded and disappeared as they appeared.

Subaru sighed slightly, clasped his hands in a strange way and when he was going to say the words to free stronger dominance. "Mom! Look at that man! He's really handsome! Can you ask him his name?!" A little girl's cry experiencing her first love prevented her from taking her action.

"Dear keep walking, he may be a noble, don't you remember what I told you?" The mother responded quickly as she looked at Subaru, although she was to fascinate for a few seconds she returned to reality to start walking quickly dragging her daughter with her. Thanks to them Subaru was finally able to realize all the bustle, conversations about commerce, screaming demanding money, flirtation attempts and the sound of slapping exposing the failure of the latter. Subaru finally realized, no sorcerer had the ability or the ridiculously immense amount of cursed energy to generate this scenario, not even him.

"This is not some kind of sorcery..." He thought, his curses were stunned to hear the thought, nor was it someone's work, so where the hell are we...?

"We are in a completely different world." He concluded in one thought, the curses simply nodded, that was not the most logical thing, but if his god said it, then it should be true. Subaru sketched a smile looking at his surroundings now with curiosity, let one of his inventory-working curses swallow the bag he brought, settled his sunglasses, and joined the transit of people. "This will be interesting for sure!"

Reinhard Van Astrea, the Sword Saint, was walking in the streets of the capital, only a few minutes ago Marcos Gildark had ordered him to take a break, before that the Knight Commander was trying to convince him that so much work would make him crazy. Which Reinhard countered with his Divine Protections, talking that if he felt tired Od Laguna would grant him a new Divine Protection to stop being it, having already spent several minutes and seeing that debate, Marcos simply gave the order.

As he walked several children greeted him and came to play, telling him how amazing it was in addition to asking questions about the Dragon Sword Reid, to which he simply gave a slight smile next to brief answers, after all, he did not deserve those smiles, he did not deserve those compliments, he did not deserve noth- "Oh, sorry." One person had accidentally bumped into him, instantly his Divine Protection of Judgement was activated,

Reinhard was now at the bottom of a deep sea, everything was completely dark, when he tried to talk he couldn't, when he tried to move he felt heavy, it was deep, it was suffocating, Reinhard couldn't breathe. "Hey you okay, buddy?" It was the same voice that had apologized, that person was shaking him trying to pull him out of that trance.

"Uh? Oh... Yes! I' am!" Reinhard couldn't afford to worry a person, after all he didn't deser- wait, buddy?

"Oh well, you looked pretty pale and I thought there was by accident I hit you near the heart or something." Did the man say releasing a relieved sigh, Reinhard finally gave the time to look at him, a noble? "You can say I'm new to the city...kingdom… whatever, I really don't know where the hell I am, the last thing I'd want to do is make enemies." He said by giving a smile to the redhead, Reinhard could feel true warmth, warmth directed towards him, he had to apologize, no sane person should show that smile to a monster like him.

"I'm sorry." Reinhard slightly bowed his head, but was raised by a foreign hand, that man rejected his apology.

"Why? You didn't do anything bad man, are you those who have a problem of self-esteem? I guess they exist in this world as well... Oh, it looks like I'm diverting." The man extended a hand toward him, Reinhard had much to process, among the failed apology, problems of self-esteem and, another world? "Natsuki Subaru, call me Subaru." The firm voice of the man brought Sword Saint out of his thoughts, looked at the man's extended hand, and and without further delay shook it.

"I'm sor-"

"No "I'm sorry," just your name." Again that man, Natsuki Subaru, Subaru had rejected his apologies, Reinhard forced himself to leave his thoughts of self-contempt to his side.

"…Reinhard Van Astrea."

"Reinhard uh, that's sounds German but the surname sounds Russian I guess, well, nice to meet you pal." He made the squeeze a little stronger creating a sense of closeness, friendship.

"The pleasure is mine... Subaru." Reinhard said firmly with a smile on his face, while he thought it impossible what that man was doing, he simply decided to take advantage of it while he could, Subaru smiled slightly.

"Well, I'll keep touring this place if there's anything interesting, I'll see you some other time." The "nobleman" said, breaking his handshake as he prepared to set out on his way, Reinhard returned to his thoughts of self-contempt in less than a second because of that, after all, he did not deserve something as wonderful as a frie-

"If you hear someone screaming your name for help, it's me! Later!" Perhaps that was the fourth or fifth already neither knew, of the times he had interrupted him, Reinhard turned toward the source of the voice watching Subaru move away by shaking his hand slightly waking up.

"Later..." He whispered to himself as he watched him lose himself among people, remembered all that overwhelming power for a few seconds and then replaced him with the image of the handshake, a big smile trying to contain some that another tear, he stood firm with his forehead high and started walking, they would definitely look again, definitely.

Emilia was in the middle of a chase, a person had stolen her badge, an object that gave her a chance to thaw her people from the Elior Forest, had to find her at any cost, following the only clue she had bent in an alley and encountered a somewhat peculiar scene.

There were four men, three lying on the ground asleep while the other stood counting the coins from the bag he had kindly asked of the sleepers. "Lia, be careful with this guy, I feel... fear of him. " Puck told him in his mind, he could swear that his voice was shaking, but that wasn't important, he took a defensive position for anything. "So you're the thief who stole my insignia?" He said aloud to draw his attention as the gelid air took over the alley. Subaru simply turned to stare at Emilia, a shiver ran through her entire body.

"Oh, I think you confuse me with the cute golden hair and red-eye girl who happened upon me... thirteen seconds ago." Emilia noticed how the man looked at her above her shoulder, and from one moment to another, all that pressure and fear had gone. "I think I should be the overprotective, not you." Said the man in his mind, the real reason behind the pressure felt by the half-elf and the floating cat was a colossal chinese dragon inhaling and exhaling in his neck of the girl, Kaku, it was only enough for his gaze to disappear, the man had left Ryu, you could say that Kaku's brother with Reinhard so that he could find it easily, which caused the dragon to want to take advantage of the situation and be even more protective with his master. "Same plan, stay hidden until I say otherwise." He communicated to all his curses.

"Eh?! You saw causally if she had a insignia like..." Emilia began to make a triangular shape with her hands which she showed the man. "this size?" Subaru recalled something gleaming in the girl's hand, as she had nothing better, she decided she had to do her good deed of the day.

"Kuro, go look for the girl, when you find her, let me know. Don't let them see you." The curse nodded feeling as Kuro quickly walked away, once he called a curse was visible to normal people, he would have to take care of when he called Kaku or Ryu. "Well, I saw something small and gleaming in her fist so I guess that'll be that."

Emilia's eyes lit up next to a relieved smile, he could still save his people.

"If you want I can help you search, after all I have nothing better to do." He said as he let the curse I use to store his bag eat the bag with 27 gold coins, which Emilia looked surprised since from his perspective the bag simply gone.

"Oh, you don't have to do that, really, with that information is enough, a half-elf like me will only cause you problems..." Emilia said as she lowered her head as an apology.

"I really don't care if they look bad, everything can be fixed with universal language."

"Universal Language...?" Emilia was slightly confused by lying her head to one side.

"Yeah, it's called violence, just kiding. I'd like to lend you a hand, you remind me of some people in my home." Subaru deepened his gaze on Emilia, had a great resemblance to the "Angels" of his world, both were beautiful, the very stubborn never wanted to teach him their techniques. "Natsuki Subaru, just tell me Subaru."

"O-Oh, all right! hey... My name is Sat-" Puck who had kept quiet and in alert mode cut off the words of the half-elf.

"Say the truth Lia." He said in a serious tone rare in him, although Puck knew that this lie would not hurt, he did not want to risk deceiving such an entity, and with his mere presence, it was obvious that he was not at his level.

Emilia was frozen for a few seconds in the words of her father and then looked directly at Subaru. "Emilia, just Emilia."

The power of friendship, yes, I'm going to make Subaru and Reinhard like Yuuji and Todou, though much better. Speaking of these two, I don't know whether to make Subaru a Royal Candidate, leave your opinions.

Subaru has two great abilities, Flawless, his Jujutsushiki which allows him to learn, employ and perfect any type of technique, both sorcerers and curses under two conditions, the ritual has to be seen by him and the ritual will have to harm him.

And the Cursed Eyes, not official name, I accept proposals, the possessor of the eyes automatically becomes the god of curses, when they ask to be by his side, curses become part of the possessor of the eyes, that is why they were transported with him, the possessor can make curses visible if he wants, but that will also make visible the cursed energy he and the curses employ.

Subaru won't have Limitless or RbD for obvious reasons, but it will have Red, Blue and Purple.

Ah, the only character I'll take from JJK will be Dagon only for his Domain Expansion, wink wink.

Later.
