Haikyuu Mafia Au

Chapter 1

"C'mon Tsumu!! Were gonna be late, and I wanna make it early so I can talk to my friends and not be the lame one!!!"
"Shut up osamu, your so annoying! And they are my friends to!"
"You point?"
"Boys!" Their mother called out. They turned around and bowed.
"Sorry mom."
"You boys are 13! You should act your age," The boys looked up, smiled, nodded and hugged their mom.
"Bye mom!" They said in unison
"Bye my sweet babies!" Both boys walked into the school and  headed to their classes. They started talking to their friend, fighting, joking and laughing. By the time school was over they were extremely happy. When they got in their home Atsumu's smiled faded. Osamu walked to their father.
"Hey dad!"
"Osamu, my boy!"
"Hello father."
"Atsumu. Have you grown out of that disgusting phase yet?"
"You can't force a person to change their sexuality."
"Excuse me boy?" The man walked over to the boy and slapped him. Atsumu was on the verge of tears, he held his face with his hand.
"Go to hell." Atsumu said. Their father gave him a bigger glare and punched his stomach. He puked a little and the man turned his direction towards Osamu.
"Osamu come. Let me show you what happens to f*ggots who don't listen."
"Yes father." Osamu was on the verge of tear for his brother. Atsumu had constantly told him to not say anything, don't interfere, and don't express yourself. Their father grabbed Atsumu by the hair and pulled him out of the house. They had owned a private land  with a huge lake. Atsumu was being dragged by the hair to the docs.
"W-Wait dad he can't swim!!"
"That's the point!" Osamu tried taking the man's hand off  Atsumu, crying.
"Osamu back off!!" Atsumu yelled. Their father pushed osamu off and threw Atsumu into the lake. Osamu was sobbing. He tried running after his brother to save him but the man grabbed the neck of his shirt.
"SAMU!"
"ATSUMU!!! ATSUMU NO- PLEASE TSUMU!! BROTHER!! NO ATSU-" The man knocked out Osamu and picked him up. He left the scene without a second thought.

*5 hours later*

"Im home! Where are my boys!" Osamu was crying and his father was sitting at a table with a 'dreadful' look on his face.
"Osamu what's wrong, where's Atsumu?" The woman looked to what her son was looking at. It was a shrine, fear filled her eyes.
"N-no."
"I'm sorry dear... He died to a horrible accident, correct Osamu?" Osamu kept silent looking at the shrine. His eyes were red as tears continued to pour out.
"Correct father." The woman collapsed to the floor and started crying. She was staring at the ground processing what was happening.
"No! My baby!" The man stood up at looked at the woman on the ground. He gave an evil smirk that Osamu saw. He wanted to kill him, torture, make him feel pain. He looked back at the shrine.
"I'll get revenge Tsumu... I swear." He muttered under his breath.

*meanwhile*

Atsumu woke up with a pounding headache. He looked around as his vision cleared. He was on a mat in a blank room. He looked around trying to figure where he is.
"Oh, your awake! Hold on, I'll get Oikawa!" Atsumu froze hearing a voice. It was boy that looked his age. He had spiky dark brown hair. He ran out and came back in with a boy who looked the same age as the other but had more light and fluffy hair and a lighter shade of brown.
"Hi, im Oikawa." Atsumu didn't say anything but tear up.
"Osamu."
"Your name is Osamu?"
"N-no! My twin, where's Osamu!" Atsumu stood up frantically before collapsing with major pain in his leg. 
"No, lay down! Your gonna cut it open again!" Atsumu looked at his leg which had a huge deep cut in it.
"We'll help you find your twin, just lay down on the mat!" Atsumu calmed down with the sting in his leg.
"I thought I was dead... Where did you find me?" Oikawa looked at the other boy.
"I found you floating down the stream... I got Oikawa and we nursed you back to health." the boy said. Oikawa put his hand out.
"Let's try this again! Hi, I'm Oikawa"
"Im Iwazumi."
"What's your name?" Atsumu was silent a moment before taking Oikawa's hand.
"Atsumu."

*8 years later* 

"Shhhhhh! You beautiful bitch, shut up!" Atsumu whispered screamed. Oikawa rolled his eyes
"I know, you perfect Whore! I needed to tie my shoes!" Oikawa whisper-screamed back. Both boys snickered before calming themselves.
"Ok joking aside we need to get this jewel, also why'd they send you on this mission? Your injured," Oikawa questioned.
"Our mission was to get the jewel if possible but if not at least put a tracker on their truck." Oikawa nodded and peaked by the wall.
"They are here!"
