Todoroki one shots + other random fandom one shots

Mistake and Together

Summary: (demon slayer Todo) So this is a RWBY x MHA x KNY chapter and a secret siblings Au/Twins Au and Yuki Todoroki Chapter who was disguised as Shoto at birth semblance and weapon is the same, Yuki is a professional Huntress on Remnant and is a Hashira on earth, At age 1-12 Yuki was raised on earth with his two other quirkless sisters Sakura and Kori (Sakura is older and Kori is younger), Sakura died due to a demon and Yuki and Kori became demon slayer Hashira's, at age 13-15 Yuki and Kori was sent to make an alliance with the Huntsmen and Huntresses of Beacon academy where Yuki is training to be a Huntresses but then Beacon fell on her first year of school and she is the same age as Ruby too and both of them were moved up because of their silver eyes, Kori was already a professional Huntress since she left before Yuki and she is part of Ozpin's group so she was already aware of the relics and Maiden's and Salem, Kori was the previous Summer Maiden but no one knew not even Ozpin. While Kori was protecting Yuki from Grimm during the Battle of Beacon she died and passed her powers to Yuki who self taught herself to use the Summer Maiden's power, after she went to Atlas and somehow became a Huntress she went back to earth to slay demons, Aiko has no idea he had three other sisters. Yuki is 17 almost 18 so she is like a year older then Shoto. 

No one's POV

Yuki was looking up in the sky sitting at a ledge of a cliff next to a water fall and Giyuu was walking up to her "hey Yuki, why are you here?" Giyuu asked "I could ask you the same question Giyuu" Yuki said as the two laughed "yeah, I need a break from Shinobu annoying me, what about you?" Giyuu asked "when I was a child my sisters took me outside to look up in the sky when we were sad" Yuki said "oh... I see, I know how much you miss them sorry for bring this up" Giyuu said "it's fine you didn't know Giyuu, besides it makes me happy doing things me and my sisters used to do with you and your sister" Yuki said as the two chuckled a bit. While Yuki was finished after her mission she was wearing her cloak with a hood, the heroes thought she was a criminal so they arrested her and now she is in a cell under U.A high school and was being guarded by All might and Present Mic then Principal Nezu came to talk to Yuki "tell me child what is your name? Or what should we call you? What is your gender and pronouns?" Nezu asked "...my code name is Snowing Icicle you can call me Icicle or Snow, and I go by she/her and I am a 16 year old girl" Yuki said "well you are old enough to be in this high school as a first year and since your not an adult yet you will be attending rehab here at U.A since it is a new program" Nezu said as the teachers and Yuki was shocked "Nezu! That might not be a good idea you know" All might said "oh I just want to know if this program can change the minds of villains, so for now on any villain who is not a adult yet will be attending U.A's rehabilitation program" Nezu announced "um... isn't that a little extreme? I mean you guys said so yourselves that I am a villain" Yuki said "yes we know but we believe we can change your life if we turn you into a hero" Nezu said "...what's in it for me?" Yuki asked "I'm glad you asked! We will provide everything you will need for school plus until we get more villains for the rehab program you will have the very top floor to yourself, the dorms for villains are slightly bigger then the students rooms and you can decorate it anyway you want, everything you will need is being provided for you and any other villains that will be in the program, and besides you will be in class 1-A, and once a month you can contact your family" Nezu said and Yuki looked away "... my family doesn't know I am alive, as soon as I was born my father abandoned me and my oldest sisters raised me I don't know how they are doing now because I'm not with them right now" Yuki said "okay we will provide therapy too" Aizawa said "now then Snowing Icicle, will you be in the rehab program?" Nezu asked "fine... I got nothing better to do anyways so this will kill some time until I get bored" Yuki said "while your at U.A security will be watching you at all times" All might said "ew, your going to watch me use the bathroom too? Perverts" Yuki said and Midnight slapped All might on the back of the head "All might that was stupidly worded anyways, we will be watching you at all times BUT when you need privacy you will be alone, like showering, using the bathroom, sleeping, changing, you know all the things us girls need" Midnight said "okay then I like that better then what Bunny stick skeleton man said" Yuki said and some of the teachers were holding in a laugh "okay then you will have these quirk canceling bracelets so you can move your arms around freely along with this quirk canceling collar and in case you try to escape it will be a shock collar so it will send a large amount of electricity in your body and not a normal person can stay standing when this is on half and not to mention if it is on you won't die we will try everything to not kill you understand?" Nezu asked "so it's a collar that will not kill me but I will fell like I'm gonna die?" Yuki asked "yes! That is a good summary" Nezu said.
