As Dumbledore sat in his office he stroked his beard as he looked through the list of wizards that would be coming of age and came to one that caused him to falter. "That, can't be right wasn't she found to be missing?" he pushed up his half-moon glasses as he took a closer look at the paper. The sound of breaking china was heard and caused the old man to look up from his work, and the sound of footsteps could be heard as a woman exited a gap with eyes looking around.

"Ah, Dumbledore I can assure you that is all correct. Well, mostly correct since one little witch is in Japan." the woman opened up a fan and started to chuckle at his confusion.

"Who, what, how did you even get in here?" Dumbledore's mind was spinning at how someone was able to enter Hogwarts and so easily from the look of the woman.

"Oh, I have my ways. But the little witch is perfectly fine; albeit her mental state is that of almost worshiping Mima. But besides that, she has a good head on her shoulders and is quite resourceful. Talking about Mima she had to pull a few strings and favors to even get Marisa into Japan via me." The youkai chuckled as her shikigami walked out and looked around the room.

"Oh, but where are my manors, my name is Yukari Yakumo. Sage and protector of Gensokyo; the land of fantasy. The last true bastion of magic and the supernatural." the youkai's eyes turned into slits as it chuckled once more. "Now tell me Dumbledore... why you even desire the little Kirisame at your school? I know for a fact that Mima knows more about the foundations and how to push magic to its limits than what anyone in Britain can do besides maybe a couple unrivaled wizards and witches."

Dumbledore sweated for perhaps one of the few times at that name. Mima was but a rumor yet her achievements that were even known to be done were nothing to sneeze at. it was said that she had taken on a dragon with just her magic and won. and the notes she did take about her magic and its capabilities were bone-chilling, truely Mima was a master of the art of Magic and was truly terrifying back in her day.

"I want Marisa to come to my school cause if she follows Mima's path we could all be in danger." he looked at the youkai with a begging look only for Yukari to smile evilly as she closed her fan.

"Are you sure you want to have favors hanging over your head for me to use whenever I please?" The youkai said with a warning. When the old man nodded reluctantly Yukari nodded before speaking once more.

"On her Birthday I'll open a way for you to come to her home, Only you may enter, and if I see anyone else had entered there safety will not be guaranteed. Oh and before you go and say about this place... don't cause it will just end in ruin for you. Well then Ran, Chen you can go back home I assume so enjoy the trip here. But I'll be taking my leave." At the end of that note, the youkai opened a gap behind her before exiting Hogwarts to prepare; leaving Dumbledore with his letter to prepare for the heir of the house of Kirisame.

-Fast forward to May, 12th 1991-

It was a calm day in Gensokyo as a certain apprentice could be heard quietly breathing. It was the redhead's eleventh birthday and her master was letting her sleep in. the vengeful spirit sighed as an old man with a white beard came out of the fireplace. He stroked his beard as he looked around at the simple home Mima had made for both her and Marisa, much to the annoyance of the Hakurei clan; even if both clans children got along really well even if both children's guardians advised otherwise.

"Ah, Lady Mima I wasn't expecting you to be here." The Vengeful spirit had heard rumors of the man and as such had a reluctance to trust his achievements in full. But she was going to try and make an effort to at least be friendly first.

"Oh hello, Dumbledore would you like something to drink? Tea perhaps? Water maybe?" the vengeful spirit forced a smile as she heard Marisa get up.

"Ah, it looks like Miss Kirisame is up. But I have something for you, in fact, Lady Mima." he would open his small sack and grasped something before pulling out a bottle of Firewhisky. "A gift from me to you and ah, I almost forgot the young witches letter to Hogwarts." the man's voice had a calm and almost sleepy charm to it as noted by Mima.

"Miss Mima? Where are you?" The high voice of Marisa could be heard as the young witch came running in putting on her purple witches hat as she went quiet at the sight of the visitor. Dumbledore looked at the witch taking in her features. The witch was almost unhealthily short for her age but from the looks of it, she seemed perfectly fine with her condition.

"Ah, you must be Marisa Kirisame. It's your eleventh birthday if I recall correctly?" The magus asked as he pulled a letter out in pristine condition. After seeing a nod from the witch who had taken the letter; she started to read it out loud.

"Hogwarts School of Witchcraft and Wizardry Headmaster: Albus Dumbledore (Order of Merlin, First Class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards) Dear Ms. Kirisame, We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on September 1. We await your owl by no later than July 31. Yours sincerely, Minerva McGonagall Deputy Headmistress"

Marisa had a confused look on her face as she looked at Mima. "I don't understand what this is for? You said you would teach me all I would need to know." Bluntly said she wasn't pleased with these turns of events.

Mima sighed as she turned to Dumbledore. "Please explain yourself, because I will not have my apprentice be taught the rules that hold you witches and wizards back. So you better give me one good reason why I should let Marisa here go halfway back across the world to some school?" Mima was notoriously known for her short tempers in Gensokyo and her destructive power should something not go to plan.

Dumbledore spoke once again with a voice completely calm but with control of the situation. "Ah, please be calm Lady Mima, all this is simply an invitation for Marisa to come to learn at Hogwarts. But I think we can arrange you two to have a temporary place of residence in Britain as to not having to portkey over to Europe. Plus I had to give a few favors to a certain sage to even come here."

Marisa started to look at this list of things before looking at both of the adults. "B-but. Miss Mima, we don't have any money to purchase any of this stuff." Mima sighed as she had a feeling Marisa would be interested.

"Marisa, if you are truly interested and willing to work hard at Hogwarts… I guess I can arrange for you to learn at Hogwarts. BUT! You must make me proud and show the rest of the students just what makes a true magic user differ from the others." Mima smirked as Marisa never backed down from a challenge and was wide-eyed and ready to make her hero proud as she giggled.

Dumbledore soon left as the two were having fun on young miss Kirisame's birthday. A couple hours passed as Mima was taking Marisa to her birthday gift. "How much longer? My legs are tired." Marisa whined as Mima said a few more steps before taking off the witches blindfold.

The witch's eyes grew in size at the sight she saw. It was a broom for Marisa. "I LOVE IT! THANK YOU MIMA!" the witch ran over to the broom and looked it over, as the ancient spirit chuckled at the witches actions. Marisa gasped as she had an idea. "Can I fly with it?" her voice peaking in excitement as she looked at Mima with joy.

"But you wouldn't be a witch if you couldn't fly on a broom of course. Also your welcome my young apprentice." And thus began Marisa's journey to Hogwarts.

-Authors notes-

Oh man my first story on here is a crossover. And to be fair I'm not sure how this story is going to go but I do plan on at least going through year 1 if only to get a feel for if I want to continue this or not. I may or may not add Alice and Patchouli to the mix. Though to be honest I decided on a more friendly Mima as well as changed a few things to help straighten a few things out.

Something's I should note are that Marisa is from England and was moved to Gensokyo via Mima who was instrumental in making the formulas and some of the plans for the Hakurei barrier and used her favor from Yukari to get Marisa and herself into Gensokyo.

While I haven't completely decided the house Marisa will be in Mima definitely is either a Ravenclaw or a Slytherin (even though she never went to Hogwarts)

So I decided to try and make one. While I have read the books and seen a few of the movies its been a few years so my Knowledge of Harry Potter is a bit rusty. So if I messed up anything important tell me and i'll try to fix it. Though I'm not sure how often i'll post for this.

Edit: 9/4/18- Realized I had messed up a couple of words and fixed them to the correct character.

Edit: 9/6/18- Fixed the bold in the first chapter
