Shirou emiya is an experienced man, due to this he can face any situation with a semblance of competency, having faced many situations most people would rather not, Shirou Emiya can call himself a veteran of many.

He is not afraid of trouble, though most of the time he chase after trouble to himself rather than the other way around, the idiot. But, somehow thing got under control by virtue of dumb luck or an assist from someone else, her name didn't need to be said or mention, he still owes her a lot of debt, like A LOT, better put his mind on something else rather on the debt he accrued. Not to mention the thing she said will happen if he off himself before paying his debt.

Heck he even got himself a geass to not die or making any other contract with any entity until he pay of his debt, quite the through girl she is.

Regardless Shirou Emiya consider himself an experienced man, unfortunately his experience didn't amount for one thing against the creature in front of him.

Kischur Zelretch Schweinorg.

This is going to be one of those days isn't it?

Sigh.


He knew Zeltrech appearance in front of him is a trouble, but what he didn't expect is that Zeltrech himself would be offering assistance to relieve him of his problem.

What is the problem you asked? Well, apparently some higher ups in the clock tower finally figured out that he is researching for a reality marble, a forbidden magecraft. This making him a suitable target for a sealing designation.

What they didn't figure out was, he didn't research a reality marble, he already own a reality marble, not that help with his situation, if anything that just makes him a much desireable research subject to the higher ups, thus more reason justifying them to make him a sealing designation target.

He was on his way to escape London when he suddenly arrived from his motel room into another place by opening the bathroom door, the place he arrive is a familiar one with a desk and a chair along with another familiar figure looking at him across the desk.

Zelretch

He sighed, contemplating which is the best choice, become a test subject of a magi or become a plaything of a vampire. Mind you either choice is not a desireable one, but he had not much opinion on the matter. At least if he died it would be by his own choice, right.

"Alright, what's the verdict?" Shirou said toward the vampire. Said vampire on the other hand is just smiling hearing this question.

'Shit, wrong question.' Shirou thought cursing himself. He should have asked whether if he can leave as soon as possible, fuck. The vampire then speak word that confused the heck out of Shirou mind.

"I can help you." The vampire said.

What...


So to summary what he understand from Zeltrech explanation, he needed help exploring another dimension, and what he meant help he mean cannon fodder, all he needed to do is live there for a few years until the heat around him cool down and zeltrech will uses his influence to deal with his current sealing designation status.

Not a bad deal, except...

"And how will I return, wait, no, will you even remember to pick me up for that matter." Shirou asked Zeltrech.

"Well, you just have to trust me then Mr. Emiya." The vampire replied not assuring Shirou at all.

"Can I refuse?" Shirou asked cautiously.

"Sure." The vampire replied, exciting shirou a lot.

"Good luck, getting out of clock tower Mr. Emiya." He continued, burning shirou excitement to the ground.

There is no way he can left clock tower without a fight, not in one piece at least, damn it. The choice is between living in another world for who knows how long until the vampire pick him up or stuck in a jar living a life not a life, huh? It wasnt that hard of a choice after all.

"Fine, I'll do it." Shirou said resigned. He had a bad feeling about this.

"Excellent, first, let me adjust something for your trip." Zeltrech said cheerfully.

Shirou bad feeling intensified.


"Why am I a child?" Shirou asked, irked obviously.

"You need to be a child of 11 years old to complete what I asked of you," Zeltrech said.

"And when you're recover to original age I will fetch you back, not too bad of a deal right?" He continoud.

"Right..." Shirou replied dispirited.

The task Zeltrech ask of him is an easy one albeit took a long time, a really long time especially against some third class magus like him.

The task is to observe and note the difference of the magic system with his dimension, and also to see if it is possible to learn and assimilate the spell between the two system, in order to do that one needed to learn this world system from scratch which is not easy even for zeltrech, who didn't have the time for it, so he needed a volunteer to do his job, i.e shirou emiya.

Luckily for zeltrech there is a school to teach the basic of Magic here in this world, problem was it was only for children age 11 to 18, and while he can turn himself into a child using magic, why do it himself when there is a volunteer to do it for him, i.e shirou emiya.

And thus shirou was turned to a child for this job, damn his E rank luck. While shirou cursed his luck zeltrech transported him out into a back alley and called out to him.

"Well welcome to the Leaky Cauldron, Emiya. Your new home for the next several years, enjoy." He said.

Leaky Cauldron?

Seriously


Shirou right now is sitting in a tavern, looking around he can see Zeltrech speaking and laughing with the bartender or owner of this place, other that that this place looks like an ordinary medieval tavern. Does this world still in the medieval age?

His musing is cut short when he saw Zeltrech and the owner walking toward him.

Shirou stand up when they reach him and spoke.

"Emiya, this is Tom, the owner of this place and also your host until your graduation." Zeltrech said introducing the old man beside him.

"So this is the boy?" Tom asked.

"He looked quite mature for his age." He mused.

"Indeed he has been through a lot, this one," Zeltrech said.

"He will be staying with you when he is not at hogwarts, please take care of him for me." Zeltrech said faking a tear.

"Of course, you can trust me Mr. Schweinorg i will take care of him like my own son." Tom said to the vampire.

"If it's you Tom, I can rest assured." He nodded before continuing.

"Well I need to leave right now, I'll send his school supplies the day after tomorrow, take care." He said while leaving for the door, Tom and Shirou watching him leave, shirou in relief, and Tom in shock, he just leaves like that?

After recovering from the shock he looked toward the kid that left and said.

"What a busy man he is. So kid, what's your name?" Tom asked looking down toward the boy.

Shirou looked back toward the old man and introduce himself.

He somehow felt a bad feeling about this.


His feeling was right, after he told Tom, the pub owner his name, his face looked shocked for a second before nodding as if he understand everything.

He didn't know what Tom action means but he dare bet that its anything but good.

On the other hand Shirou is currently in the kitchen cooking dinner for the customer, Tom said he didn't need to bother, but Shirou insisted that he helped.

It will be the day after tomorrow his luggage will arrive, in the meanwhile he will explore this place tomorrow with Tom, as per zeltrech instruction.

Surprisingly he didn't feel anything will go wrong tomorrow. It must be a blessing.


"Alright, now that we're done with Gringgot, time to start your tour shirou." Tom said delighted.

Shirou and Tom is currently at Gringgots, apparently Zeltrech didn't just dump him on the spot and leave, but he gave shirou quite the sum of money through Tom. In order for him to safely uses them they need to go through Gringgot, the equivalent of Central Bank for wizard, first.

"But first, here is your vault key." Tom said while giving Shirou a key of some sort.

"With this you can take your money out of Gringgots at any time, but because your still underage you need a presence of your guardian. But once your of age you can do so on your own." He explained to Shirou who is looking at the key.

Huh, what do you know, it is quite the convenient, though they can do without the goblin, they are nasty, Shirou thought while remembering the goblin who welcome them.

"Now, this way my boy, were going to visit Madam Malkin's Robes for All Occasions first, for your school clothes. I bet she will love to see you." Tom said dragging Shirou to a certain shop.

Welp, this is going to be a long day shopping.


To Shiro emiya the trip in diagon alley went well.

He got his robe from Madam Malkin's Robes for All Occasions.

His quill at Amanuensis Quills.

His books at Flourish and Blotts.

Eat ice cream at Florean Fortescue's Ice Cream Parlour.

Bought candy in Sugarplum's Sweets Shop.

Tom offer to go to Magical menagerie to buy pets, but shirou consider his future schedule decided not to add another responsibility on his shoulder by caring a pet, thankfully Tom didn't insist as Hogwarts didn't require pets to be mandatory.

"And that is the Daily Prophet office. There is only one wizarding newspaper in Britain, discounting such small circulation publications such as The Quibbler. The Daily Prophet, whose headquarters are in Diagon Alley, it is delivered by owl on a daily basis to nearly every wizarding household in Britain." Tom said to Shirou.

"Next were going to Ollivanders, to get your wand." Tom said excited, confusing Shirou.

"Wand?" Shirou ask confuse.


Apparently in order to use magic this world are using wand as a medium for casting spells, and while there is proof that magic can be use without wand or a wandless magic, they are not taught to children like himself currently, at least here in Britain don't. Someplace around the world like Africa magic community on the other hand encourage it, instead.

The reason why, was because European wizards were generally used to using the tool and found wandless magic more difficult, requiring much more concentration and skill to perform these spells.

Wands were manufactured and sold bywandmakers, the most famous of these in Great Britain beingGarrick Ollivander, and in Eastern Europe,Mykew Gregorovitch. Each wand consisted of a specific type ofwoodthat surrounded acoreof magical substance. Although the wand cores might come from the same creature, or the wood might come from the same tree, no two existing wands were exactly alike. Wands were often buried along or burned when their owner died.

Just now Shirou and Tom are leaving The Ollivanders after getting him a proper wand. Which is a 14 inch wand, hornbeam wood with unicorn hair, mr. Ollivander, the eccentric man who sold him the wand commented, the wand is unusually hard to bend and to be carefull with it so as not to break it in two, it seems the length is a bit unusually long which is why Tom suggested to buy a holster with it, Shirou agreed with the older man.

"Welp, now that you got your wand, let's go back home, I think your luggage is already there." Tom said to Shirou.

"Next week will be the time for you to leave for Hogwarts so you better prepare yourselves well Alright." He continued.

Shirou just nod, while asking some things about magic to Tom, which he is happy to answer for him.

After all if he started school next week he's going to need all the help he can to start his damn job.
