The Potion Master's Daughter(Assassination Classroom, Harry Potter Crossover)

Time for E Class

Hanako was currently mad at the twins. She never thought that they would go as far as using her pocky to prank her. Her hair is now a fire red and it grew out to her waist. On top of that, the twins also charmed her eyes to go the inverse colors. So there she was, sitting down in the great hall for breakfast, causally eating some pocky, when her hair changed colors and her eyes went green with black specks. Everyone else besides Fred and George also had similar problems, but they mainly had their opposing house color hair. Ravenclaws had yellow hair, Hufflepuffs had blue, Slytherins had red, and Gryffindors green. Honestly, Hanako loves the color green so why couldn't she be apart of the group?
     For her first potions class, she was stuck with the prank along with the rest of the school. But it really shocked her when she got to the dungeons and when Snape walked into the class, he whispered, "Lily?".
"Miss Hanako, will you please explain yours, along with everyone else's hair color today?" Snape asked recovering from shock.
"Well Professor, it seems as there are a set of twins who desire to prank and happen to think that My sorting went wrong and that I should go ask the sorting hat to place me in one of the other houses it recommends." She answered glaring at the two pranksters.
"Understood Miss Hanako, 50 points from Gryffindor for Mr and Mr Weasley's school wife prank." Snape said in a cold tone.
"What?!"
"You have no proof..."
"That we did anything at all!" Fred finished.
"You two have the same hair color you started with. That will be Detention with me starting after dinner." Snape answered with a smirk.
"Not Fair" they both whined.
"We were going to brew the cure for boils today, but instead," he waved his wand and new instructions appeared on the board, "Today we will be brewing the antidote to the color changing potion. Miss Hanako, you may go speak with the Headmaster now if you wish. Use the point me spell to get there." Snape said.
"Thank you Professor." Hanako said then walked out the door. She took out her wand and promptly said, "Point me", and she followed a set of gold tracks to a tall griffin statue. "What would the password be? Lemon drops? Fudge? Peppermint lolli?" A stairway revealed with the last guess. Hanako was laughing on the inside for her accurate guess of the Headmaster's personality. She walked up the stairs and reached a door then quickly knocked.
"Come in" Dumbledor answered.
Walking quietly, she entered the room and greeted the Headmaster.
"Why, Miss Hanako. It is nice to finally meet you. Professor Mcgnagall would not tell me much about you, not even how she knows you. But why are you here? You should be in potions right about now." He asked.
"I wish to be resorted. Gryffindor is not the house for me." She said strongly but not too loudly.
"Well, to be resorted, something as serious as disownment would have to happen. You understand that I cannot just let you change houses after the first day. Gryffindor is the best place we have to offer and you should be proud to be a member of the house" Dumbledor states.
"Bit sir, I really belong in Slytherin." She argued.
"No, I will not have a possible child of the light straying to the house of dark. I do not have a confirmation of who your mother is but I am almost 100% sure and she would not stand for her child being in Slytherin after what those snakes did to her at her time here. So, go fix your hair and eyes, put on your best smile, and go act like the Gryffindor poster girl. I have plans and I cannot have you messing them up. I don't care what Mcgnagall says at this point. So go back to class and become a side character." Dumbledor said sternly, twinkle gone from his eyes.
"Headmaster, have a nice day." Hanako said calmly and coldly.
She went back to potions and started on hers and finished in record time.
"5 points to Gryffindor for a perfectly brewed potion within a small time limit. I thought you were getting a house change?" Snape questioned.
"The Headmaster decides that I would be better off behaving as a Gryffindor poster girl. I figure that means I should lose as many points as possible without getting expelled. Don't you think Professor?" Hanako said coldly but with a small smile at the end.
"Of course. In that case, 10 points from Gryffindor." He said with a smirk.
"Thank you sir." Hanako answered then took a sip of her potion. The length of her hair stayed the same, but it turned back to its natural pitch black. Her eyes stayed the same though, so she just waved her wand and changed them back herself with a spell on the first page of the charms book.
"15 points from Gryffindor for using charms in a potions classroom." Snape said.
That marked the end of potions so she went to the rest of her classes without a bother the rest of the day.
    A few weeks have passed and Hanako hasn't even talked to the twins once. She had been hanging around with Selena Abernathy and her friends in the Slytherin common room. She hadn't made any other friends in Gryffindor besides the twins, and now everyone in Gryffindor thinks of her as a house traitor. But then came the day it was time to go to Kunugigaoka. Hanako went to Professor Mcgnagall's office for their afternoon tea and brought her school uniform and supplies with her as well.
"Hello again dearie, is it time for you to go to that other school?" Mcgnagall asked.
"Yes it is, my friend just texted me that school starts in two hours." Hanako stated calmly and pulling out her phone to the message.
"How have you gotten that device to work here? All muggle electronic devices malfunction when near Hogwarts." Mcgnagall questioned.
"My friend bought this phone for me. I looked into why it worked and found that there are small runes engraved in the phone case that allows it to act almost like a wand and it works with the flow of magic instead of on the flow of electricity. I need to ask Asuno where he found it so I can track down magical Japan." Hanako said sipping at some tea.
"Yes, I looked into that for you. Luckily enough, magical Japan is a few streets away from your school and the laws in Japan are next to none. You will be allowed to do magic there 24/7 without any problems." Mcgnagall stated almost troubled by the fact.
"Well, thinking back to it, most of the street performers I have seen have almost all been using magic. People make a living off of it in the muggle world and pass it off as a new type of technology or skill. It is quite impressive how they hide in plain sight." Hanako said smiling.
"Yes, quite. Now get to school, you do not want to be late on your first day." Mcgnagall said handing the girl her bag.
"Goodbye Professor."
"I have told you before, call me something less formal when we have our chats." Mcgnagall scolded.
"Alright, goodbye Bachan!" Hanako said with a smile before using her port key to go to school.
She appeared in the woods before the E building then started running to make sure she was the first in the classroom. Once there, she sat in the back and started on her potions essay homework.
One hour later
    No one was arriving yet, she was just a bit too early, but at least all of her Hogwarts homework was done and revised. Having nothing else to do, Hanako pulled out her phone to text Asuno.
H: How long till school starts?
A: 2 hours, I wanted to make sure you got there in time.
H: So you decided that it was a good idea to make me three hours early?
A: I was just trying to be a good older brother. Just do your homework for your other school then.
H: I finished that 5 minutes ago.
A: Read ahead?
H: I finished all of the textbooks through 7th year. They were all easy to understand.
A: Then go explore the city for an hour and come back. I am sure all your classmates are still asleep.
H: Good point. I have wanted to look around anyway.
A: Just make sure you are not late. I will call you when you should start heading back.
H: Bye my favorite brother figure!
A: I should be your only brother figure. But goodbye.
    Hanako left all of her things set up in the back but put her wand in her inner vest pocket and put her wallet in her front pocket. She ran through the woods, over a small stream, and pass a creepy grandmother who was offering her candy before she got to part of the city. She cast a quick point me spell and found herself in an area of old shops. She went into one and decided to look around.
Suddenly, a old lady appeared and said, "Oh, you are a young child of the Fae! Blessed by Kami aren't you? Follow me, I will take you to your kind's place of business!"
Hanako was confused but followed since she wanted to find out where the magical side of Japan was anyway. Curse her Hufflepuff side for her trust! But the lady knew what she was doing because she lead Hanako through the back of her store and into an alley way that wasn't there before. There were several shops, one was a broom store, a store for all techno magical needs, an apothecary, a rare herb store, book store, divination store, healer shops, curses and counter curses shops, a ramen stand, and several dessert shops.
After thanking the woman whose name was Sakura, Hanako went and bought some magical pocky that would provide any missing nutritional needs up to 5 hours after consuming and change flavors. She also ended up purchasing a laptop that always has WiFi, cannot break, self charges, as well as using a blood lock so only she could use it. The last thing she purchased was some divination cards that you control mentality in the air so you cannot get a messed up reading due to errors in shuffling. But before she could go into another store, she got her deadline text from Asuno. Hanako quickly came out the way she came and said goodbye to Sakura.
"Have a nice day Fae child." Sakura called out as she left.
She ran to school quickly and was still the first person so she decided to dissect her potions book and make it better with her own notes. She got done with the following potions: cure for boils, pepper up, sleeping draught, color changing, and instant energy before a few people started to enter so she put all of her things away besides her new laptop for notes. No one noticed her so she decided to not draw much attention. But, who walked into the room after that point was shocking.
Karasuma walked into the room with a large yellow octopus. After going to Hogwarts for a few weeks, Hanako was used to weird things, so it was not much of a surprise when she was the first to get over the shock and wave to Karasuma. Even more shocking to everyone else, was when he waved back with a small smile.
"Alright, there is no easy way to put this, so I am just going to flat out say it. We, the Military Of Defense, need you to kill this thing. We came to an agreement with him that he will teach this class and not harm any of you. It is just easier since we will have a better track of him and he will be in a place with people who have motive to kill him," Karasuma states with a lack of emotion.
(Random point of view change since I am dead tired after Lacrosse practice and too lazy to fix it,)
"What? You want us to kill him when the military can't?!" Some guy in the back yelled. Honestly, as school representative, I need to know everyone by now. Was it Terasuka? Possibly, I will just wait for role call.
"Practically, but whoever kills him or as a group will get a share of 100,000 yen." Karasuma answered.
I wonder what investments I can make with that? Maybe I should go speak with the goblins about multiplying my money with good investments. I will do that soon.
"Why Hello class! I am the one responsible for the moon being partially destroyed, and I will do the same to the Earth come the end of the year. So go ahead and try to kill me! I bet you can't!" The yellow thing taunted gaining green stripes.
"If you can't already tell, the green stripes mean he is looking down at you. We got quite a few of those back at base." Karasuma states before starting to stab at the thing.
"Now, you will also notice that it travels rather quickly. We have clocked him at a max of Mach 20. And, he for some reason has a thing for grooming eyebrows!" Karasuma said while still trying to stab it but getting his eyebrows done by it instead.
"So you want us to kill this alien?" Another kid in the back asked.
"Woah, I am not alien, I am of Earthly origin! Thank you very much!" The yellow thing protested.
"We at the MOD will be providing you with the means to kill him. These weapons are harmful to him, but cannot harm humans. The perfect tools for a classroom setting. Now, everyone will be getting to start, one knife, and one gun. Any questions?" Karasuma asked revealing the weapons.
"Yes, when can we start?" I asked starting to like E class much better than A class already.
"Anytime you want Hanako." Karasuma answered.
