Disclaimer: I in no way own Harry Potter or the Fate franchise. I am not making a profit off of this story, so please don't sue me. If you are, can I point you over to some other fanfic authors that are guaranteed to have more money than a poor student?
Author's Note: Well, no one guessed where I got the name Mashu from. T.T But it is the name of the mountain that Gilgamesh goes into after he killed a bunch of lions in search of immortality in the Epic of Gilgamesh. But I didn't know that Mashu was also servant shielder in Fate/Grand Order. Though if you want to friend me on Fate/Grand Order, my ID is 910,137,052. :P No idea if the commas are needed though. Well then…
Story Start!
Platform
"So the ticket says to go to platform 9 ¾ hmm," Enkidu mused before glancing up at Mashu, who was imitating a life-like lion cub plushy while being draped over her head. "I'm pretty sure that it's that mass of prana that's gathered around that pillar between platform 9 and 10. Think that's it?"
Mashu yawned imperiously, staring down at her, before going back to looking like a life-like plushy.
"Yeah, I shouldn't have asked that should I, seeing as that's the only mass of prana at King's Cross Station. Well then, let's go."
Train
"We managed to get a compartment all to ourselves, didn't we, Mashu?" Enkidu said, sitting down.
Mashu climbed down from her head, before lying down beside her.
"I wonder how Hogwarts will be like, Mashu. I don't believe that it would be anything like the adventures Gilgamesh and I had. It'll be a nice experience though, don't you think?"

"Anything off the cart dear?" A woman pushing a snack cart asked, after knocking on the door.
"Mashu, would you like to have anything off the cart?" Enkidu asked quietly.
Mashu huffed, eyeing the selection of snacks, before turning his head away.
"No thank you," Enkidu smiled, "but thanks for asking."
The lady with the snack cart left the compartment. 'What a polite young lady. I sure wish more children are polite like her.'
Castle
"First years! First years over here!" A large man yelled, waving at them.
Enkidu walked over to him, along with the other first years. When all the first gathered around him, he shouted, "Follow me!"
He led them down a path and some stone steps with some of the first years slipping and sliding on the wet steps until they arrived at a lake.
"Four to a boat!"
Enkidu got into a boat, with some other first years, with Mashu still lounging on her head.
When the boats turned, and the castle appeared within their sight, gasps of awe were heard.
"The castle is beautiful isn't it, Mashu," Enkidu murmured.
Mashu purred in agreement.
Sorting
"Potter, Harriet!"
The students all started muttering, as Enkidu walked up towards the stool.
"Daniel Potter has a sister?"
"Is she some muggleborn that happens to share a name with The-Boy-Who-Lived? She can't be a Potter, she looks nothing like them!"
"She looks so pretty!"
"What's with the lion on her head?"
"Ms. Potter, please remove the lion on your head so you can be sorted," Proffessor McGonagall said sternly, her eyes softening as she eyed the lion. 'Definitely a Gryffindor for sure, that Ms. Potter.'
"Of course, Professor McGonagall!" Enkidu gently relocated Mashu from her head to her lap, as she put on the Sorting Hat.
Processing...error...mind cannot be comprehended...too complex...too foreign...no human-like mind structures...deploying diplomatic personality...
'Nice to meet you! I'm the Sorting Hat! I would have to ask though, what are you doing here at Hogwarts?'
'Nice to meet you too. Well, I'm just here to fulfill a promise to some people.'
'So, you aren't here to cause harm to any of the inhabitants of Hogwarts, are you?'
'Nope. What fun would it be to fight such weak people?'
'Well, as you aren't here to harm, let's get on with the sorting! ...erm, is it possible to allow me to see your memories so I can sort you? I promise that no one will be able to see what I see here, and I will not speak of this to anyone.'
'Sure!'
'To be reunited with your friend, what a noble goal you have. To think that death is not as permanent as we thought it was for your friend, the Throne of Heroes is truly a wonder. I welcome you to to Hogwarts, and I hope you find what you need to find your friend in...'
"RAVENCLAW!"
Troll
"Troll! Troll in the dungeons!" Quirrell screamed as he rushed into the great hall, fainting as he got in.
"Everyone, go to your common rooms!" Dumbledore commanded, mobilizing the teachers to search and remove the troll.
"Mashu, seems like it'll be a great adventure! Let's go defeat the troll!"
Mashu harrumphed in agreement.

"I can sense an inhuman presence near the second floor bathrooms!" Enkidu said excitedly as she ran, "There's the troll!" She engaged battle with the troll with a punch to the head, only for the head the fly off the troll and hit the wall.
"So I guess it can't stand my A-ranked strength," Enkidu muttered as she sighed. "Well, let's get back to our common room, Mashu. That was a pitiful adventure. And to think that the troll was only a bit harder to fight than the acromantula in the Forbidden Forest."
Stone
A thousand souls, no more, no less. Crystallized when they were in pain, forever trapped in the form of a red stone called the Philosopher's Stone. The world whispered, demanding the removal of it from human hands. Enkidu stared at the mirror where the stone was hidden, felt the stone being placed in her robes, before shrugging, and tossed it into the Gate of Babylon.

A couple days later, Quirrell was found in the room where stone was, with mirror shards around him, with Voldemort's face on the back of his head. His death was theorised to have been caused by magical backlash, which usually only happens when a powerful magical item is destroyed without proper precautions.
Prairie
"Well Mashu, we'll be visiting your pride next," Enkidu said, as she unboarded from the Hogwarts Express. "Though I do wonder, why did I not see Lily and James Potter at Hogwarts? After all, they did make me promise to go. Though I do remember a boy with black hair and brown eyes that would approach me, only to run away. Well then Mashu, let's go!"
Mashu sweatdropped, holding onto Enkidu, as she ran out of King's Cross station.
