Osamu?!

MHA x BSD

Shota Aizawa is Osamu Dazai older half brother.

Haruki Aizawa is Shota and Osamu's father.

Haruki's quirk is like Shota's but with speaking (he nullifies by saying the person name and quirk.)

Haruki has medium brown hair and red eyes.

Kiyomi Aizawa/Hirayama is Shota's mother and Haruki's wife/ex wife.

Kiyomi has black hair and greyish black eyes.

Kiyomi is quirkless.

Oksana Dazai is Osamu's mother.

Oksana has long dark brown hair and dark brown eyes.

Oksana's ability is called 'A Touch Of Human' it allows her to turn inanimate objects into humans and control them with a single touch.

The combination of one parent with an ability and the other with a quirk had made a unique and rare occurrence. Osamu Dazai was one such case. Having an ability like his Mother but a power similar to his Father.

Oksana Dazai is the daughter of the previous Port Mafia Boss. Mostly no one knew that Oksana was related to the previous PM Boss only a few exceptions same with Osamu.

Haruki met Oksana when he was visiting Tokyo during a business meeting. Haruki had a big fight with Kiyomi before leaving for the trip so he thought a one night stand could help him forget about it. Oksana was in Tokyo because of some PM business. Oksana ended up pregnant with Haruki's child.

Kiyomi found out Haruki had a one night stand with another woman. But decided it was better to stay together for Shota.

Haruki didn't know Oksana was originally from Yokohama. (Meaning Shota didn't know the same about Osamu.)

When Shota was 13 years old and Osamu was 5 years old.

Osamu went to meet his Bio father because his mother was dying. (Someone from a rival organization of the PM poisoned Oksana. With something that has no cure. It was because Oksana was a very skilled and feared member of the PM.)

This caused Kiyomi and Haruki to have a divorce. They have shared custody over Shota.

When Shota was 18 years old and Osamu was 10 years old.

Oksana's father killed Haruki because of his downhill spiral mourning for his daughter.

Kiyomi and Shota only know that Haruki was murdered but does not know who did it or why.

Osamu was left in the custody of his grandfather the Port Mafia Boss after his mother's death.

Mori and Hirotsu mostly took care of and looked after Osamu while his grandfather was on a down hill spiral.

After his grandfather was killed Osamu was left in the custody of Ogai Mori his mother's childhood friend who was like a brother to her.

Shota hasn't seen Osamu since he was 20 years old and Osamu was 12 years old.

Shota doesn't know Dazai has a ability he believes he is quirkless.

Shota and Hizashi are married.

They adopted Hitoshi Shinso when he was 14 years old and had him for 2 years. They adopted Eri when she was 6 years old and had her for 1 year.

Chuuya and Osamu started dating when they were 15 years old and got married at 18 years old.

Osamu still leaves to go to the ADA but he kept in contact with Chuuya since they were married. After Osamu laid low for 2 years they got a penthouse and started living together again.

Chuuya has longer hair.

Chuuya has a back tattoo of Black wings.(A reminder of what happened in Stormbringer)

Chuuya and Osamu are wearing casual but still nice day off clothes. Chuuya left his hat at home so it wouldn't get damaged outside of Yokohama.

Hitoshi replacement Mineta in class 1-A.

Shota's Pov
I was teaching when the doors to the class room burst open. A tall man with brown hair and casual clothes walked in with a goofy grin on his face. "Shota it's been so long!" The man said as he draped his arms on me. I moved his arms off of me. "Do I know you?" I asked. The man dramatically gasped. "How can you not remember me your own little brother?" The man asked dramatically. "Brother?!" I said. I then realized what he meant. "Osamu?!" I said surprised. "Yep it's me!" The man said with a grin. "Damn, Osamu how long has it been you were only a kid the last time I saw you?" I asked. "It's been 10 years and I was not a kid I was 12 years old." Osamu said crossing his arms childishly with a pout. I rolled my eyes at him. "How the hell do you deal with a class of skrunkly little humans everyday?" Osamu asked. "They're not that bad Osamu. Let me guess you don't have any kids." I said. "Well not officially obviously but I do have a subordinate." Osamu said. "Osamu stop fucking bothering your older brother we have a meeting in 30 minutes." A male voice said outside the classroom door I could hear someone pacing back and forth. Osamu rolled his eyes. "Who was that?" I asked. "Just my partner we're here on business but I thought it would be a good idea to see you while I'm here. Well bye see you later!" Osamu said then he walked out of the classroom. 'I wonder what business they work for?' I thought to myself.

Later in the training area

"Okay class Principal Nezu has decided it would be a good idea for two ability users from Yokohama to train you for the next couple of weeks." I said. The class of course complained about this. I deeply sighed. "Oh it won't be that bad Shota you'll have me teaching them!" A voice said. I turned to see Osamu. "What do you mean Osamu?" I asked. "Oh I guess you really didn't know. I was born in Yokohama. My Mother was originally from Yokohama but she met Father while on a business trip in Tokyo." Osamu said. I was a bit surprised. "Why didn't Dad say anything while he was alive?" I asked. "Because my Mother didn't tell him. She didn't think it would be important for him to know." Osamu said. "Wait a minute you are an ability user?!" I asked in a surprised voice. "Yep my Mother was one and so am I. No Father didn't know that either of us was an ability users." Osamu said. Before I could ask any more questions. "I had to change into training clothes no way I'm letting my good casual clothes get messed up during training." A voice said. I turned towards the voice to see a small ginger that had their long long hair in a ponytail with black shorts and a black undershirt. With black gloves on and black sneakers plus a black choker. "Chuuya!" Osamu said happily as he walked over to the ginger. Osamu quickly hugged the ginger. Then let go of the hug before he lent down and gave the ginger a quick kiss on the lips. "Osamu." The ginger said calmly with a smile as he returned Osamu's quick kiss on the lips. My eyes widened in surprise. Soon the two of them walked over to me. When they stopped infont of me. I looked between the two of them. Before my eyes finally hardened on Osamu. "Osamu the way you described it I thought you two were work parthers not fucking lovers." I whisper yelled. "Well you didn't ask." Osamu said crossing his arms as he rolled his eyes at me. "How was I suppose to ask when you left immediately after that?" I asked exasperatedly. "Well anyways this is my boyfriend-" Osamu was cut off when the ginger lightly elbowed Osamu in the stomach. "He is lying to you again I'm his husband my name is Chuuya Nakahara it's nice to officially meet you." The ginger said.
