No one's POV

Shoto was sitting in the cabin he was staying in for a class trip and he was texting the demon slayers when all of a sudden Iida barged in the cabin "Todoroki we need your help now something happened to Midoriya" Iida said as he was out of breath "what happened explain on the way there" Shoto said as he got his shoes on and Iida explained what happened to Izuku and Shoto speed up to see if it was true and when they arrived Shoto's eyes widen in horror his ex boyfriend was acting like a demon with red eyes and sharp eyes and his nails where also sharp. "Todoroki freeze him so we can restrain him" Aizawa ordered "no... how? Wait who turned him into that?" Shoto asked "um some guy that looked like Michael Jackson?" Denki said "Kaminari that was a stupid idea" Jiro whispered and Shoto got his sword out and kicked Izuku to the ground and his foot was on Izuku's chest which wasn't what anyone was expecting "this is why I wanted you guys to hate me so they wouldn't do this I failed my mission and now he is a demon and once someone becomes a demon there is no way of turning that person back I have to kill him" Shoto said "WHAT?! YOUR GOING TO KILL MY SON?!" Inko yelled "he is no longer your son but a creature who will devour human if I don't kill him he will go and devour humans and I have enough problems already" Shoto said as he lifted his sword up but everyone noticed he was trembling 'damn it stop shaking I can't show fear I can't let my emotions get in the way' Shoto thought to himself as his other hand was on the handle of his sword and he had to scream to let his emotions out and swing his sword to the ground and Izuku closed his eyes tightly then opened it again seeing Shoto's missed and saw tears coming down "Todoroki?" Izuku asked as Shoto widen his eyes "...so you have your human memories? That's good at least" Shoto said as he put his sword near Izuku's throat "wait... STOP! IT'S JUST A PRANK!" Fuyumi yelled and Shoto widen his eyes and Izuku got up and took the contacts then the fake nails and then the contacts out and Shoto was shocked "this was a prank?" Shoto asked as he looked angry and slapped Izuku across the face "oi! You bastard why did you-" Bakugou got cut off by the angry Shoto "THIS WAS A STUPID FUCKING PRANK?! YOU MAY HAVE GOTTEN AWAY WITH IT THIS TIME BECAUSE I HESITATED IF I DIDN'T LET MY STUPID EMOTIONS GET IN THE WAY THEN I WOULD'VE KILLED YOU HERE NEVER DO THIS AGAIN IF MY COMRADES WERE HERE THEY WOULD HAVE CUT YOU IN PIECES!" Shoto yelled as it started to rain and he took his hair out and Rei recognized the brooch Shoto was wearing "I'm done now I broke the rules I should go back to the headquarters now... and explain to the master" Shoto said as his crow landed on his shoulder "demons spotted in Tokyo! *Caw caw* Tokyo! Go to the village in Tokyo now!" the crow said and Shoto looked up "I understand" Shoto said as he walked pass the class and put his finger on his ear piece "Giyuu, where are you now?" Shoto asked as he put his hand on the brooch and changed his clothes into his uniform "I am heading over to Tokyo now we were assigned the same mission" Giyuu said "okay I'll see you there" Shoto said as he was smiling and turned to everyone else. 

"For now I will be leaving but I will be back soon" Shoto said as he turned into a bunch of snowflakes and went to Tokyo and everyone tried to fallow him and once they were able to catch up somehow Shoto went back to his normal form and started to run to Tokyo "how much stamina does he have?" Sero asked as everyone had to use their quirks to chase after Shoto "and he is fast" Kirishima said "Giyuu I'm almost there meet me at the usual spot then we can head over to Tokyo together"' Shoto said "understood but are you okay? You sound different" Giyuu said "yeah I'm fine I can tell you on the way there" Shoto said as they got to a place with a little waterfall and a lake with a random rock in the lake and Giyuu arrived "you look different do you want to sit this mission out? We can get you a replacement if you are not feeling well" Giyuu said "I'll be fine" Shoto said as he got a crystal out "we will get the other part and you will fin out what our sister wanted to tell you" Giyuu said putting his hand on Shoto's shoulder "thanks Giyuu that means a lot to me" Shoto said hugged Giyuu and smiled "there you are back to normal now lets head to Tokyo" Giyuu said "is he used to the emotionless kid showing emotions?" Tokoyami asked "lets fallow them" Aizawa said "yeah lets fallow him" All for one said "wear these so the other heroes in Tokyo won't arrest you guys yet" Momo said giving them large haori's and wigs then went to Tokyo and they noticed the two demon slayers hid their swords and are having a conversation and they were staying in a inn near the village "what are they doing?" Izuku asked as they got close enough to listen to their conversation "you know what you have been acting weird today do you need someone to talk to?" Giyuu asked "huh? Oh no I am fine Giyuu-san I am completely fine" Shoto said giving him a small smile "you know you shouldn't hide your emotions behind a smile I know you do this to avoid anyone from worrying about you but know it makes us more worried your still a child but you act more like an adult I know you took a huge responsibility at a young age but you know you have people who care about you" Giyuu said and Shoto had a tear come down his eyes "I-I... thanks Giyuu" Shoto said and then heard a scream "down the alleyway, lets go it might be the demon that has been going around here we don't know how strong that demon is but lets go now" Giyuu said as the two ran towards the alleyway and saw some no rank demon slayers fighting a lower moon "which twelve kizuki is that?" Giyuu asked "apparently it's the lower 2 the new one and from the looks of it that demon has learned more about their power fight with caution" Shoto said as he got his gun out "alright then... demon slayers! Move out of the way" Giyuu said and the demon slayers did it without knowing what they are doing and Shoto started to shoot the demon's legs and Giyuu cut the arms off and Shoto got his sword and charged at the demon from the front and Giyuu did the same from behind and together they beheaded the demon and Shoto sensed something but before he could run back the demon was already turned to ash and the thing Shoto sensed was gone. 

"Giyuu here are some bandages any hurt demon slayers try your best to come towards us so we can provide some aid" Shoto said as he wrapped a demon slayers arm and some kakushi members came and also wrapped them up and to the severely injured ones he used his healing powers to heal their more severe injuries "wait can't you heal us all the way though?" A demon slayer asked "no not yet I can only heal more severe injuries and minor injuries I can't heal both minor and severe injuries yet because it takes up a lot of energy for me and I will soon feel light headed" Shoto said as he started to sweat "Shoto, take a break we can take them back to the butterfly mansion so Kocho can let themselves heal" Giyuu said "yeah but that demon harmed many demon slayers" Shoto said "hey I want to know how did you guys defeat that demon so easily? We lost some members because of that demon and you guys defeated it faster then we could all together" another demon slayer said "we're rank Hashira of the corps" Shoto said "NANI?! Oh wait I-I'm so sorry mister um Hashira?" Another demon slayer said "just call me Shoto no need to be formal around me or call me anything formally I am not that kind of person" Shoto said as he got up and had a little headache from using his powers to much "headache?" Giyuu asked "mhm" Shoto said as he sat on the ground "hey summon a box I can carry you so you can sleep" Giyuu said as Shoto summoned a box like what Urokodaki made for Tanjiro and Nezuko and he opened the door and shrink down and went in the box "wait is he a demon?!" Another demon slayer asked "well half demon" a kakushi member said "then why is he part of the demon slayer corps?! I thought the corps mission is to destroy all demons" another demon slayer said "yeah but he is both human and demon he told the master himself if he does kill a human without permission he will be in his demon form and burn in the sun" Giyuu said "yeah like lady Nezuko" a kakushi member said "isn't that the demon girl who is travelling with a demon slayer?" Murata asked "yup, those two have been accepted by the master and he wants everyone to accept them as well" Giyuu said "well it might take some time" a demon slayer said "that's fine as long as you guys can accept them I won't be angry" Giyuu said "wait what?" A demon slayer asked "master Tomioka he is overprotective over his friends and comrades some of them call him dad and they also call master Shoto mom but they are only like a sibling relationship nothing else I swear to god someone told them they were in a romantic relationship wow did they spend 3 weeks in a hospital" a kakushi member said.
