well i think i am gonna go with sunrise in the dark due to the feedbacks.
As Naruto made his way to vale while guarding Weiss, he began to panic about him being in a brand new world, like the language is the same, but what about the money, or vocabulary, or this aura that sound like chakra or this semblance that sounds like a bloodline. and he doesn't even know the map!, the previous adrenaline of battle has calmed. his outer facade is calm, but his inner self is panicking.
Weiss
she was questioning of the blond, she still didn't understand where did he came from, but as she wanted to ask, another question popped up, how did he know where she was? or did he even know who she is? she was confused when he didn't even know what is a semblances or aura, he said something called chakra which he used is like aura, which is explainable if he came from a random village that used their own names about things, but if that village's hunters are this powerful, than why did none of them ever hear of it? don't be wrong, she respect him for rescuing her, but... she doesn't really know him. plus that portal the guy came out of was weird. not like there isn't portal semblances, plus his aura feels powerful, too powerful, it has an overwhelming and warming feel. it is like a warm light surrounding her entire body that is pressing her slowly, suffocating her in the most comfortable way possible. she was thank full, she was scared and she thinks he is a god!
after 3 days of travel
they passed through vale, Naruto was amazed at the architecture of this brand new world, it looked like a world that was built with precision from the beginning, structures that perfectly lined up with the street, perfect windows, doors, everything! he was amazed, stunned, words stopped on his lips and he just stared, awed at the city that looked as if it was built with a ruler the size of a bijuu. but before he could start asking questions he got lead to a "bullhead" basically a flying metal box! metal box shouldn't fly... right?
as soon as the bullhead took off he regretted it, bad idea bad idea bad idea~~ it is not like he hasn't flown before, but a metal box shouldn't fly, or even be able to hover in the air! so what was left in front of the very amused Weiss is a blond sitting cross legged on the ground covered in sweat crammed into the corner with a face greener than the gross nasty disgusting and demonic spinach. And if it wasn't for her emotional training at the hands of her father to make a "perfect" daughter, she would've been on the ground laughing when the bullhead landed and he all but kissed the ground in prayer to never fly in the bullhead again. but unknown to the blond, he would have to spend much much more flights in the flying box of death and doom, and judging by the giant laughter inside his head from a certain giant furball, he could guess he didn't look the calmest in front of the girl.
schnee manor
at the first sight, some one could say that it was an apartment building, not a mansion for only 5 people and some servants. and from what Naruto heard, the only person even bothering with weiss was Winter Schnee, her sister was like itachi to sasuke from what he heard, so he expected a calm, smart collected and an amazing fighter as a sister. but he didn't expect a father that didn't even look amused by his daughter's return home, the only reaction was when winter came out and smiled at her little sister, the kind of smile present on all loving siblings, only then did her father look liked he cared about her, only for him to realize he only cared about Weiss's sister Winter, and that the entire expression was just a mask on display for Winter.
10 minutes earlier
Winter was in her room waiting for Weiss's return after they (she) sent out another squad to send for her, but as she was reading, a powerful signature of aura was felt by her and her first reaction was to cover her room with glyphs, but as she reaches out with her senses she felt the origin of the signature is on a bullhead heading for the manor, no aura is that potent that far away, but as she said that her mind can only yell out one thing, attack! her first reaction was to grab her sword and outfit, then she saw that it got passed the defense of the manor, only a SDC vehicle has that level of clearance how did they bi-pass it?! Winter now accompanied by her guards passed her father's room when they headed towards the front gates. armed plus ready, and just as she walked down the stairs she saw her sister, she bolted down the stairs as father greeted them with his usual stoic face. as she slowed down and met her sister, she saw a blond boy roughly 12 years old that was radiating the godly level of aura seemingly just by standing! she was defensive of her sister, and never let her guard down when she grabbed Weiss and ever so slightly positions her hand closer to her sword, the blond noticed this and his legs bend only slightly to allow him to jump away at a notice if a fight ever starts.
"Winter!" Weiss yelled out after her sister grabbed her and gave her an almost bone crushing hug.
"it's good to see you too Weiss." the afford mention Winter spoke calmly with a smile smile at the edge of her lips, she then looked back at the blond in front of her
"hello you must be Weiss's sister, I am Naruto Uzumaki, nice to meet you!" the blond spoke out the greeting in such a manor almost all doubt and wariness seem to fade from her mind "umm yes I am winter, nice to meet you too." the calm and collected opposite of the blond spoke out.
"hello young man, i expected my daughter was treated well in her return?" the man with a mustache and a suit spoke out, emphasizing daughter with spoken venom in word.
"y-yeah totally no harm done!" the blond spoke out waving his hands in the air in front of him trying to deflect any accusations.
"this man, I don't trust him, those eyes are the ones that belongs to someone who uses all the power for his own good, selfish goods. just like Madara." the nine tailed fox spoke a word of caution to his host
"can tell, just look at Weiss's fear of him." Naruto knew those eyes of Weiss's father, the eyes of the villagers directed at him in konoha before he became a hero, or the eyes of Sasuke before he got over his avenger complex. The eyes of disgust and anger. distrust of him, anger for Weiss's many failures where her sister performed flawlessly and uncaring gaze.
little did Jascques know, at that moment he made an enemy with a GOD.
2 years later
in a guest room close to Weiss's own.
"is it possible?" a teenager with sun kissed blond hair asked to no one in sight.
"partially, you obtained it, you didn't create it, but it should be possible, although it's full strength requires you to unlock your own. Which is impossible, even for you." a voice appeared in this boys head, giving him his answers.
but before he could dive deeper into things, the door opened to his room.
"I-I." a girl wearing a white strapless dress, bell sleeved bolero lined in red, and white hair with light blue eyes almost stumbles into his room.
"what's wrong Weiss?" the blond asked her while bring her into an embrace.
"win-Winter is deciding to leave... for the atlas military..." the young women choked out while crying.
"that is her choice, we can't do anything about it." the blond spoke in a voice calmer than the summer breeze
"but N-Naruto, you are good with words, can't you make Winter stay?" the girl begged him
Weiss knew that Naruto wouldn't use his natural charm to manipulate people against their own will, but it didn't hurt to try.
"no i will not, it is her own decision, not yours, mine or Jascues's decision." his voice confirmed what she already knew, but there was another problem at her heart waiting to be released.
"wi-will you ever leave me?" the girl cried out to him, normally this behavior is going to be punished by her father, but the blond in front of her proved to her long ago that as long as she stayed with him, he will protect her.
flash back
"you couldn't even master a simple glyph!?" the man in a suit yelled at one of his daughter's lack of skill.
"I am sorry father! I will train harder!" the girl said, tears at her eyes.
"no! I will not let the heiress spend more wasted time on your disappointing trainin-" but before he could yell any further, the hiraishin kunai flashed and a blond arrived to the scene
"and you will stop this!" the blond boy yelled at him, scaring him into a whimpering mess as a wave of killing intent rivaling the kyubi's own crashed onto the man.
"and Weiss will continue her training, under no rule should it be stopped!" the killing intent pressed down on him further, now traces of malice is present in it, and his eyes turned crimson red with a black slit.
"yo-your eyes~" Weiss whimpered out as she could feel the pressure in the air slowly crushing her.
"they are red, i know!" the blond's voice went into a deep growl, beating the life out of Jascues's face.
red bubbles starts bursting on his skin, malice grew in the air. everyone can feel it, the people down on the ground in atlas felt it, the grimms felt it...
"but we cannot waste more time! Winter needs to complete her training at atlas academy! we cannot waste more resour-" his rammbling was stopped with a hand
"I will be her trainer." the blond spoke out to both Jascues and Weiss
"how?! you are not even 14 ye-" he was cut off again by sirens blaring
"attention attention, all walls breached, all walls breached, code black emergency!" the sirens wasn't even finished when a Nevermore the size of a bijuu crashed through the manor, causing the ground to shake.
grimms start to fill all the holes in the walls, their only target was the manor, completely ignoring everything else, 4 king taijitus crashed through the walls while a horde of at least 9000 other grimms piled in, ursai majors leading beowolves, ursais, and nevermores spear headed the charge. and over the distance there were two looming figures in the air heading towards them at a fast dive, now they had a wyvern and a sea feilong providing air support to the ground troops that were flanked by a leviathan.
Weiss saw a battle that couldn't be won, Naruto was already molding chakra and Jascues is planning an escape.
but what she didn't expect is for this battle to be won, and never mind that! 1 person won that battle!
as all hope seamed to be lost, everyone felt the presence of a god, or what they thought was one.
Naruto began glowing a golden color as he blitzed towards the army and laid waste to the entire field, 7 clones dealt with their own battles easily, and the main one was killing hundreds in one second. when some trained hunters couldn't take down a pack of ursai by them selves, Naruto was slaughtering them with practiced ease, in less than 1 minute the entire army was gone, left only was the king taijitus, leviathan and fliers.
Naruto rushed towards the 4 king taijitus and crushed their heads with a simple punch. he then went up to the leviathan and transformed into a giant golden 9 tailed fox, who used it's jaws to behead the beast. and as the thousands of nevermores attacked, he ushered the words "heavenly attraction of all earthly objects!" all the grimms start being pulled towards him before he threw his kunais in the air, teleporting in between them and slaughtering them all.
the two remaining beasts was caught by two sage chakra bijuu rasenshuriken and was shredded to dust quicker than ashes.
only then did he drop everything and walked back up the stairs to the half destroyed mansion and nonchalantly said "that's why I will take Weiss in, if not only to teach her how to defend her self."
flash back ends
"I will never ever leave you." the blond God told her as reassuringly as he could.
Weiss knew he wouldn't, but his reassurance made that seed of a doubt wash away.
"shouldn't we say good bye?" the blond spoke, Weiss could only nod her head yes.
