Todoroki one shots + other random fandom one shots

Father and son

Summary: So when Shoto was a baby he was abandoned by his family and Muzan found him in an alleyway then he was supposed to be raised to be food but then Muzan grew to Shoto raising him to be a normal child instead and Shoto can give orders to the demons but he is only a human. Muzan will do anything for Shoto since he saw him as his own son. (I might make two different endings here)

No one's POV

Muzan was walking down an alleyway after killing some humans then he heard a crying baby "huh? What's that sound?" Muzan asked himself as he went closer to the sound and saw it was a baby with a bandage over their left eye "a child huh" Muzan said as he picked up the crying baby who then stopped crying when he saw Muzan's face 'maybe I could eat him' Muzan thought to himself but then the child took out their hands and held Muzan's face and giggled. Muzan was shocked since he was not used to this and saw the name tag 'Shoto Todoroki, gender: male' and decided to raise him as his own son "hey Shoto, I'm going to be your new father now" Muzan whispered to Shoto and realized he shouldn't become a demon but raise him as his own son. 

Back at the infinity castle

"Master why do you have a child in your arms?" Nakime asked "I have decided to keep this human and raise him to be my own son I don't care what anyone says he looks happy when I picked him up" Muzan said as he smiled at the baby who was also smiling "so your now a dad?" Nakime said. "Nakime, I want to have a meeting with the upper ranks bring them here in 20 minutes" Kibutsuji said as he left to get Shoto some new clothes to wear "yes sir" Nakime said as she used her biwa to teleport her to the usual meeting place and one by one brought the upper ranks to the castle. All the upper moons have arrived at the castle and was confused since all of them are still alive then Nakime teleported Muzan with the baby in his arms "master, is that baby food?" Daki asked which made Muzan overprotective as he sighed "no, this child is now going to be my son so I asked you to give Shoto a good childhood when I am not here" Muzan said shocking the upper ranks "WHAT?!" The upper twelve kizuki yelled. "Do not yell when Shoto is sleeping" Muzan scolded "forgive us master but we are supposed to kill humans not help them" Kokushibo argued "I don't care, starting today no demon is allowed to hurt Shoto in anyway if they do I will kill them" Muzan said "aww, master has a soft spot for little Shoto" Doma said making Muzan embarrassed "I think he does" Akaza teased. "I have to go now take care of Shoto and what ever you do don't kill him" Muzan said as he left the castle and Shoto woke up making the upper ranks adore him as well as Nakime as he was making baby noises "I wonder who his real family is" Gyutaro said "who knows but master must like him a lot for sparing his life" Daki said as she was allowing Shoto to play with her hair. 

15 years later

The upper ranks did their best to prevent Shoto to know that they aren't humans by saying that they are cosplayers and actors "auntie, uncles why does dad always leave at night?" Shoto asked "he works at night" Hantegu said covering up the truth. Muzan came back an hour later and saw that Shoto was sleeping and smiled he loved Shoto as his son and wants to protect him but then frowned knowing he can die at any minute because he was a human and he remembered Shoto had a magic brooch when Muzan found him and it was the truth about his real family Muzan was not ready to let Shoto go so he hid the brooch from Shoto his whole life. Shoto was walking back from getting food then he heard screaming and went over to see what was happening and when he turned the corner he saw Muzan killing the drunk siblings and faintly heard "kill the demon slayer with Hanafuda earrings" Muzan said and Shoto looked horrified and after some people left Shoto had the courage to speak out loud getting Muzan's attention. "Dad" Shoto said as he was about to cry and Muzan turned to Shoto and felt guilty "Shoto" Muzan said as he also looked at him horrified and when he stepped closer to Shoto, Shoto flinched scared that his adoptive father might kill him next but then he ran away "WAIT SHOTO" Muzan yelled. Shoto tried to tell the police what happened and they just laughed "yeah whatever kid" one of the police officers said as he slapped Shoto across the face then Muzan came seeing Shoto crying as he put up his arms in defense which made Muzan angry and without hesitation Muzan killed all the officers then kneeled down in front of Shoto as he was still afraid. Muzan looked at Shoto and saw that his slap made a mark on his face and the two stand up and Muzan pulled Shoto into a hug "I'm sorry Shoto" Muzan said as Shoto hugged back "dad, why did you kill those innocent people" Shoto asked as Muzan gripped Shoto closer to him as he allowed Shoto to cry "I kill them because I am a demon" Muzan responded "what is a demon?" Shoto asked as Muzan explained what a demon is and the truth.
