Honkai: Kamui

{8 Days Later, Hotel Room}

"....Big....Brother..... I'm.... dying.." Kiana said with a lifeless look in her eyes as she laid face first into the math exercise book he'd bought for her.

"You can do it Kiana!" He encouraged as he himself was reading a physics textbook that was way too advanced for his age, all he had to say was he, Obito Uchiha, was a genius!(Sharingan)

"Big Brother.....Help...mee..." She begged as she got up and pulled on his sleeves as Obito looked at her with a smile and then began to teach her properly "Yeah, I'll explain it for you" He smiled as he began teaching her, Kiana somehow lacked the basics and he, Obito had to teach her properly, he'd only taught her the basic of the basic in the past two days.

"...Big Brother, can this really help me use flames?" Kiana asked again doubtful as he nodded "Yeah, Because, Fire is something that occurs whenever something combustible, as in something that can be burnt-" He explained "-In the presence of oxygen at an extremely high temperature becomes gas. Flames are basically what we can see of gas that's heated." He explained to her incase she doubted him.

"Oh, okay." She nodded half understanding then froze with doubt as she looked at him "...BUT WHY MATH?!" She asked as she shook his arm, "Because math can help calculate how to use the flames with precision and launch it properly." he explained, he also didn't explain that instinct and training could also do that but, he needed his sister to study.

That's right, Obito told her that he used science as a basis for using flames and that she needed to study science before he taught her how to use flames.

".... Brother...are you lying to me?" She asked with narrowed eyes as Obito calmly shook his head "Of course I'm not lying, what would I get from lying to you, my dear little sister." he said as he lightly tapped her forehead with a finger.

"Hmm.....I believe you for now" Kiana said narrowing her eyes cutely as she continued studying and he smirked.

She wasn't the only person who hated studying but, he, Obito had to lead by example and be a model student by studying hard(Sharingan).

Obito had to say, life was calm the past few days, he had got his background set up, got his new identity and he was learning the knowledge of this world to adjust in this world, he had even got to know his new sister well.

Looking at Kiana who was struggling to do math and biting the back of her pencil with annoyance, he smiled without her seeing as he continued to read his university level physics book because he wanted to graduate early like a genius.

Baka-Kakashi can't hold early graduation above his head anymore if he graduates early too!

So, Obito was now walking alongside Kiana with a new trolley suitcase filled with his and Kiana's clothes as they walked into the airport.

"Woah...." Kiana said amazed as she looked around the airport as they walked towards the immigration area, the two of them were walking to the counter as he gave their passports to the receptionist and then entered the lobby.

"Big Brother! I want this! This too!" Kiana said as she dragged him to a snack store and took nearly one of everything as Obito sighed fondly and ruffled her hair. "Nope! Only 3 snacks in total" he said sternly.

"....Please...." Kiana gave him puppy dog eyes as her sky blue eyes shone and he felt a bit uncomfortable but didn't agree "....5 at most!" He changed and said sternly.

"...Big Brother...." She said acting pitiful as she lightly tugged at his sleeves and looked at him with misty eyes. "Fine! 10 at most." He said as she instantly got rid of her crying face and cheered.

'.....Is it really true that all Uchiha dote on their siblings?' he asked himself confused as she took some snacks and a few cups of instant noodles and he swiped his card and paid.

"Say Big Brother,.... why are we going to Japan anyways?" She asked as she ate a candy bar.....is that a Reese's?

"Hm? Because Siegfried has a friend in Nagazora who we can stay with" Obito smiled as they sat on the side and waited for boarding to start as Kiana looked curious

"The old man has friends?!" She said surprised as Obito almost choked on water that he was drinking as he laughed "Haha- I-Haha- Oh god, yeah, yeah, he has friends." Obito said in between laughter as people around them looked at him with worry as he waved and apologized.

"Ryoma Raiden, the current head of Massive Electric Industry or ME Corp, he's actually a friend of Siegfried and well, he offered to act as our guardian temporarily until I turn 18" He smiled as he explained to Kiana who nodded, not understanding what ME Corp meant.

"Woah! So this is what a plane looks like?!" Kiana asked as she rushed into the plane and looked around and walked to the first class area.

"Kiana! Don't run! I'm sorry miss, here's our tickets." He gave the tickets to the stewardess and then walked to his seat with Kiana as they settled down.

"I was so bored just sitting there!" Kiana said to Obito as they finished Emmigration and Obito smirked "You were asleep or watching some shows most of the time" he smiled, they had been on the flight for over 15 hours, Kiana who couldn't even sit still for two hours must have suffered.

"Big Brother, you were typing something the entire time! You didn't even play with me." She said as she held his hand and looked at him accusingly, "This is for our future livelihood!" He said with a smile as he patted the laptop bag, he had been writing a novel he remembered from his previous life and thanks to the ability of the Sharingan, he could remember everything he read.

He knew they had enough money due to being sponsored by AE but, it was still a good idea to make more money and bring more entertainment to the people, it was definitely not because he wanted to rip the head off of that damn HOMU that Kiana liked for some reason, definitely not!

"Ah, there's our car." He smiled as he saw a man holding the name card of Obito and Kiana as he walked towards the man who bowed to them and took their luggage then opened the car doors of the Audi A6 all in one smooth fashion.

".....Huh, that was smooth" He muttered as he let Kiana enter the backseat of the car and he entered and sat beside her.

"Greetings, Sir Obito, I'm Asahi Satou, your assistant and personal driver arranged by Mr. Ryoma." The black haired and black eyed man with an average build and seemed to be a bit elderly around 40 introduced himself in perfect english.

"Would you like to first go to your new apartment or visit Mr.Ryoma?" Asahi asked them as Kiana's stomach growled before Obito could reply.

"I think we'll first eat something Asahi." He smiled fondly as he ruffled Kiana's hair as she stuck her tongue out at him.
