Metanoia (Shigaraki x reader)

~01~

In a small house in a quiet neighbourhood a young four year old girl was getting her hair braided by her mother as she was singing songs and playing with her toys.

"You're gonna have to be still for me to do this Honey." Her mother's sweet, calm voice said as she continued to tie one of the long braids going down her daughters back.

"Sorry mummy! I'll be still." The young child put her toys down as her mother finally finished her other braid.

The little girl jumped up and ran over to the bathroom and jumped up on the counter to see herself in the mirror. She smiled as she saw the long pretty braids going down her shoulders.

"Mummy! I wanna go show Tenko my new hair! Please?!" The child called out to her mother, Okita Yuko.

"Yes, but don't be gone too long I'll miss you." Okita said to her child as she took her off of the bench and put her on the ground.

"Ok! Bye mummy I promise I'll be back soon!" Y/n said as she started running towards the front door.

"Also! Don't forget to put shoes on before you go out!" Y/n nodded as she slipped her little shoes on and ran out of the house.

Y/n ran to the end of the street to the Shimura household, as she got there she could hear some shouting from inside. She knocked on the door and the shouts stopped, she could her footsteps come to the door and she started smiling. The door opened, she could see Nao, Tenko's mother and Hana his older sister.

"Oh hello there Y/n, what are you doing here?" Nao questioned as she looked down at the small girl in front of her.

"I wanted to come see Tenko! I really wanna show him my hair!" The little girl smiled as she showed off her braids to Nao.

"Oh yes of course! And might I say it looks adorable on you Y/n." Y/n blushed at the compliment and muttered a small 'thank you' as Nao opened the door for her.

As she walked in she could see Tenko in the lounge room scratching at his eyes, her eyes lit up and she started running to him.

"Tenko!" She called putting to him as she threw her tiny body on his and hugged him.
He let out a yell as her body toppled down on his and she quickly let go.

"Huh? Y/n? What are you doing here?" Tenko questioned as she sat up straight and started smiling.

"Look, look, look! Doesn't my hair look pretty?!" She asked as she grabbed his hands and started shaking him around.

"It looks really nice! Did your mother do that?" Tenko asked and she quickly nodded her head up and down.

"We should go and play heroes and villains!" Y/n said as she got up.

"Ok I'll be th-" Tenko started but got cut of by the booming voice of Kotaro.

"Y/n I think you should leave. Tenko has to do some things for me right now." Kotaro said as the little girl nodded not seeing the expression of her black haired friend.

"Yes Mr. Shimura! Bye bye Tenko!" She said as she got up and left to go back home.

"Get our of my sight Tenko." Kotaro said as Tenko nodded and ran to Nao.

"It's a secret! This person is apparently our grandma! She was a hero!" Hana said as Tenko Looked at the photo that she showed him.

"Hana, why are you showing me..." Tenko started at he stared in awe at the photo.

"Even though dad said all that, it'll be alright, 'cause I'll always be cheering you on Tenko! Let's keep it a secret from dad and become hero siblings!" Hana said as she smiled at him.

"Yeah!" Tenko said happily as he put the picture back.

Tenko played with the dog as he thought about his grandma unaware of what was going to happen later.

"Tenko! You went into my office, didn't you!? You saw didn't you...?!" Kotaro walked out to the backyard screaming at his son.

He could hear Hana tell on him as he got beaten by his father, the dog barked loudly while Tenko got hit over and over again.

Tenko's cries were loud as he cuddled Mon and scratched at his eye tears spilling like a waterfall.

"No... I hate this... Mon... I... can't take it anymore... I just... hate everyone." Tenko said quietly.

He squeezed and squeezed Mon until he exploded.

"Wha...? M-Mon?" Tenko stuttered out as he began hyperventilating.

"Tenko!" Hana then came out "I, um... I... I'm sorry. I didn't mean it. Even though... I was the one who said it was our secret... I'm sorry."  She started apologising not noticing Tenko's scared expression.

She looked up and screamed at what she saw. Tenko sat there crying as Mon laid dead covered in his blood. She started running but Tenko grabbed her before she got the chance to get away he grabbed her and accidentally killed her. He started vomiting and crying he didn't know what was happening. His grandparents and mother stood at the door screaming seeing him like that on the ground blood everywhere, Hana and the dog dead. He reached out to his mother crying, begging for her to come and save him from whatever villain was causing this. She ran out arms open trying to grab him but died straight away, her blood splattered everywhere as he killed everyone.

Kotaro walked out of the house after hearing everything and he was scared. The blood everywhere, the ground was rocky and going everywhere. He saw his dead family with Tenko scared and screaming, calling out for him and with a purposeful killing intent, he killed his father.
