the town of Kuoh

Kuoh, Japan,

In a quiet town located in the country of Japan, there exists a very prestigious school that was once an all-girls school for prestigious families,

In the headmaster's room for the school, we can see a man with red hair and purple eyes looking gloomily at the letter in front of him,

The letter itself gave off a very heavy magic pressure that can make a middle-class level being fall to its knees,

On the letter was a crest with two swords, one black, and another white crossing each other, at the intersection of the swords, there was another sword with a demonic-looking skull on its hilt, the swords were then covered by a purple chain, red gem, and white snowflakes,

This crest had been haunting the ultimate class devil ever since the Great War had ended over 500 years ago,

The Emiya Family,

This family of mages had wreaked havoc in the final stages of the Great war and were one of the reasons for its abrupt end aside from the death of God and the four original Satans,

And now, the family head of this Clan wanted him to take in the two heirs of the Emiya family to his school,

this had the great duke Gremory quaking in his boots ,if their parents and their siblings were anything to go by, then these kids would definitely end up tearing down his school before the end of their first year,

He sighed heavily as he looked at the names of his new students,

Natsu Emiya and Erza Von Einzbern,

---------------------

Britain,

in a far off place isolated from the outside world through a very powerful barrier, there exists a majestic palace reminiscent to the Camelot in legend,

in one of the rooms of the castle,

"Why the hell do I need to go to that school controlled by the Devils?" shouted a young man with salmon hair and slit eyes, in his anger, he was accidentally encasing himself in a fire, just as he was about to continue arguing, a beautiful woman with golden blond hair and green eyes said seriously,

"Natsu, I will not hear any more arguments from you, i know that you don't' want to go to a school run by those sorry excuse of a Devils, but you must remember that you are the heir to the Emiya family after your brother refuse to become the heir, seriously, i wish you were calmer and composed like sakura's son, leaving that aside, as the only son aside from your brother Laxus, you are the only other child from your father, and as such, you will have to go to this school and represent the Emiya side of the family, so that you can mingle with the supernatural outside of Britain," she said to which the young man whined,

"But mom!!" "Stop, or do you want me to tell dear Erza that her cousin refuses to go with her?" she said with a mischevious smirk to which Natsu paled, remembering his violent cousin, he gulped as he shook his head while gloomily mumbling,

"I bet Laxus left the house to travel because he knew that Dad and Sakura-Kaa-chan were planning to do this to him, now i am stuck to pick up the pieces"

----------------------

"Remember Erza, you will not cause trouble for our cousin, if i hear from Natsu that you were violent with him again, i will take away all of your sword collection, is that clear young lady?" said a beautiful woman with white hair and deep red eyes, (author notes: here is the link to the adult Illya: https://i.redd.it/xw0kg71mgdi21.jpg)

"Yes Kaa-sama, i will not cause shame to our family name, but i want to ask, is uncle Heracles going to come with me as well?" asked the girl with deep red hair and brown eyes,

"No, he will be with your father, he along with Shirou and Kuro-nii need to go to a meeting in America with the Greek pantheon, apparently, Zeus wants to have a word with his 'son' " said Illya as she rolled her eyes, ever since the war was over and Kurono had removed the mad enchantment on Heracles, Zeus had been dying to talk to his son whom he had thought had died, after their firm refusal for so many centuries, they could not hold them back anymore, so Shiro and Kurono had decided to meet them with Heracles,

"But I heard that your sister and brothers are going to come back in a year or so," Illya said to which Erza exclaimed,

"Ultier, Grey and Arthur-nii are coming back?"

Ultier was medusa's daughter while Grey was Rin's son, Arthur was Artoria's son,(author notes: Arthur from fate/prototype)

"Yes, but remember, if you cause any mischief in the school, you will be grounded for the entire summer vacation, that means no trips with your siblings," Illya said seriously to which Erza nodded stiffly, she was really afraid of her mother when she was angry, she had personally heard from her uncle Heracles about a time when she would slaughter her enemies with a beautiful smile on her face, in fact, she remembers clearly why the clan head of her and her cousin's family was so feared and why no supernatural faction was willing to offend the Emiya clan,

On the next day, the two young people were sent to Japan on a private plane owned by the Avalon Industries, run by the Emiya clan,

author notes:

okay, so before you guys end up confused, the Emiya clan is one entity, but is made up of different branches, such as the Von Einzbern, Tohsaka, Matou the Pendragon. so as a whole, everyone is from a single clan, but the children will have their branch names in their full names,
