Todoroki one shots + other random fandom one shots

One dead one alive

Summary: (demon slayer todo) twins AU, secret siblings/sisters AU, villain Rei, Fuyumi, and Natsuo AU, So Yuki is the younger twin who was killed and her older twin Shoto who is the alive twin and uh... I got inspired when I saw someone playing a quest with Zhongli and they met Qiqi so yeah that is why I made this chapter. 

No one's POV

Shoto was in the common room with the class playing games and he normally doesn't play games with the class when Aizawa came in "class we're going to a pharmacy to collect more information about the league and we need to get a special serum that can only be found in rare plants and those plants are grown around the pharmacy so tomorrow we are going to this place and be ready for anything that comes in your way and who knows how expensive it might be and U.A has a budget lets hope it won't go over that budget so now go to bed problem children" Aizawa said and some students sighed and went to their rooms to go sleep. 

The next day everyone was in their hero costumes and on the bus to the pharmacy and when they arrived they didn't see anyone at the reception "hello? Is anyone there?" Momo asked "welcome to the Moonlight pharmacy" a voice said which made some students jump and Aizawa activated his quirk and got his capture weapon ready "students be on your guard" Aizawa said and a little head popped up and Shoto widen his eyes and the little head got a chair and stand on it revealing a little half and half girl wearing a loose kimono "a kid?" Denki asked "hello I am Yuki, what do you need?" Yuki asked "oh uh we need night flower serum" Aizawa said "do you have a document? Or your prescription?" Yuki asked "why do we need a document or our prescription?" Mina asked "night flower serum is very hard to get and it is very strong as well it needs to be in the hands of someone who will got lose or break the serum and the bottle" Yuki said "ah... we didn't bring any" Aizawa said "there is another thing as well... get a empty perfume bottle with a diamond or any gem on top the lid and hunt down a pink berry goat" Yuki said "okay she's messing with us" Uraraka said "you know what it might be rare type of goat" Denki said "Kaminari that is so dumb" Jiro said "you know what fine lets go find a empty decorative perfume bottle with a gem on the lid then we can get the night flower" Aizawa said "um sensei I need to use the bathroom I'll catch up with you guys later" Shoto said "okay but hurry" Aizawa said as everyone left the building and Shoto walked over to the counter "Yuki?" Shoto asked and Yuki stared at Shoto then widen her eyes and smiled "big brother Shoto!" Yuki said getting off the chair and running over to Shoto hugging him "but how? Your dead" Shoto said as he hugged back his sister wishing he will never let her go "I am a zombie onii-chan I am immortal now I died but I got saved by someone" Yuki said "who?" Shoto asked "I do not remember because I'm dead I have poor memory I am losing my memories of when I'm alive... onii-chan I don't want to forget you" Yuki said "don't worry little sis I will never forget you and plus I'll visit you whenever I can" Shoto said holding Yuki's face as she had faint tears coming down "promise?" Yuki asked "I promise I'll be back soon Yu" Shoto said and Yuki waved at Shoto. 

When everyone got back Yuki was sitting on a chair in front of the counter and this time she had a little bow and hat on her head "we found the pink berry goat" Izuku said as he showed Yuki a poorly built figure with pink and red berries "what is this?" Yuki asked "the pink berry goat?" Uraraka said and everyone but Shoto was hoping she would buy it "this is a blob though... wait what does the pink berry goat look like?" Yuki asked "why do you even need a pink berry goat? This is just a random thing made from berries it's probably not the pink berry goat if that does exist" Bakugou said and Yuki got off the chair "pink berry goat milk is tasty very tasty I cannot remember the exact name of the milk it was written down for me where did I put it?" Yuki asked herself as she looked through papers and found the one she was looking for "here it is strawberry milk" Yuki said "you wanted us to find a pink berry goat SO YOU COULD HAVE STRAWBERRY MILK?!" Bakugou yelled "Bakubabe chill she's just a kid" Kirishima said "excuse me everyone did I say a bad thing?" Yuki asked "no no you didn't say anything wrong he's just like that don't worry" Momo said and a little laugh came from the door behind the counter and a girl walked in and then two more people walked in which made Shoto's eyes widen "wow that was awesome good job Yuki-chan" a girl said "Makomo-san, Sabito-san, Kanae-san, Yuki wants strawberry milk" Yuki said as she walked over to Kanae "of course whatever you want Yuki" Sabito said as he got a small carton of strawberry milk and Makomo got a star shaped straw and Yuki went back to the chair and was drinking the milk happily "who are you guys?" Iida asked "I am Kanae Kocho I am the manager here these are my new friends Sabito and Makomo and you already met Yuki" Kanae said. "Okay we need to get to the point do you have night flower serum? We really need it" Aizawa said "of course as for the payment... it would be 4 000 000 yen please" Makomo said "...that's over the budget" Aizawa said "well either Todoroki or Momo or Iida can pay" Toru said "which Todoroki?" Sabito asked "nani?" Everyone but the dead ones and Shoto asked  "I'm Yuki Todoroki, Shoto's younger twin sister" Yuki said and everyone looked at Shoto "I tried to tell you guys she wanted strawberry milk but none of you let me say it" Shoto said and Yuki finished her milk and walked over to Shoto and hugged him "onii-chan" Yuki muffled as Shoto sat down and Yuki tried to stay awake then fell asleep on him "the same as usual" Shoto said "well are you going to pay for this hard to get serum?" Makomo asked "well is there a way we can make the prince lower?" Uraraka asked "ah of course there is a way we can give it for free... give this note to our headquarters" Kanae said giving Shoto a envelope with a wax seal on it with the word 'Destroy' on it and Shoto nodded "I will be right back since I am the only one here who knows where it is" Shoto said as he ran out of the pharmacy and Sabito picked Yuki up "well these three girls are hot" Mineta said "Mineta! Yuki is a child and I think Makomo is younger then us" Denki said "I'm 13 biologically but if maybe things turned out different I would be 21 or 22" Makomo said "what do you mean?" Izuku asked "we are all dead and zombies Yuki is 8 but if she was alive she would be 15 but she was also murdered so we are all cursed with immortality and Yuki is cursed with amnesia so she has trouble remembering things" Kanae said "oh... how did you guys die?" Jiro asked.

"Me and Makomo died to the same person in the same place" Sabito said putting Yuki on a large pillow they randomly have "I was killed by someone stronger and Yuki died because someone poisoned her out of hatred of her beauty and kindness which is really messed up she was helping that person's crush and besides she is only a child she never tried what a lollipop tastes like or anything related to candy she was so excited to try them but before she could this happened to her" Kanae said and Shoto came back "I'm back now" Shoto said and Makomo got a small decorative box with a lock on it "here are the keys take good care of it and once you are done or out of it come back" Makomo said giving it to Shoto "the night flower serum thanks Makomo" Shoto said and the heroes left the pharmacy and headed back to U.A. 

When everyone got to U.A the students were in their uniforms and in the classroom and Shoto opened the box and took out a purple with some gold around it and a golden lid bottle (the monster extract bottle from Breath of the wild) "this looks like the bottle" Shoto said and Aizawa took the bottle and Shoto took the box back to his desk "good now that we have it we should be able to complete this new invention that Hatsume is making for us to track down the villains Todoroki, we don't know how much we might use this so if we run out please go back to the pharmacy to get more" Aizawa said "okay sensei" Shoto said and Mei was at the forest where her new invention was being built so of course everyone went back on the bus with their uniforms on and went to the forest. 

When they arrived Mei was tightening some screws on the new machine and Shoto was carrying the box with the bottle inside "oh good you have the serum?" Mei asked and as soon as Shoto opened the box a knife came and Shoto grabbed the bottle as fast as he could and he got a small scratch on his arm "TODOROKI! Are you alright?" Aizawa asked "a knife came out of no where" Shoto said and the league came from the shadows "well little bro Shoto give us the serum" Fuyumi said "Yumi... Natsu... Touya?" Shoto asked "don't forget me" Rei said "mom?!" Shoto said as he was shocked "Todoroki what ever you do, don't give them the serum" Aizawa said and the class surrounded Shoto with their quirks activated "Kurogiri get us Shoto" Natsuo said and a portal opened up and Shoto was falling in the air "oh no I set it up to high" Kurogiri said and out of no where Yuki came and caught Shoto and she was in her demon slayer uniform "onii-chan are you okay?" Yuki asked "Yuki?! Where did you come from?" Shoto asked "the bottle has a device on it so I got alerted when it was in danger the pharmacy sells expensive and high quality things like the serum it is used to heal not whatever you guys are doing" Yuki said "Yuki? You mean the younger sister mother told us about?" Dabi asked "...who are you?" Yuki asked "Yuki don't fight" Shoto said getting up and Yuki took the bottle while Shoto was holding onto her "well guess we will have to do this the hard way" Shigaraki said and Yuki looked at the bottle and swallowed it whole "YUKI!" Shoto yelled and Yuki got her sword out and hit and made the league fall to the ground "bitch" Yuki said "LANGUAGE!" Shoto yelled "some people yelled it out at the pharmacy" Yuki said "I am so gonna kill those people" Shoto whispered to himself.
