I Have A Biological Child?!

MHA x BSD

Shota Aizawa is the father of Osamu Dazai.

It was Shota's Sophomore year when his school took him on a field trip to Yokohama. Trying to figure out if he liked women or not he hooked up with one of the local girls. The two of them didn't even introduce themselves to each other because neither of them wanted to get attached. She was trying to get over a dead lover and having a hookup was a perfect distraction for her. After that night they haven't seen each other since. The girl's name was Oksana Dazai, she had long dark brown hair and dark brown eyes. What Shota didn't know that night is that Oksana was pregnant with his child.

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.

Oksana Dazai was a Port Mafia member. She trains alongside Ogai Mori since she was 7 years old and Mori was 9 years old. They both grew up together in the slums before they were taken in by the Mafia. They saw each other as siblings.

The Port Mafia Boss at the time adopted Oksana as his own daughter training her to take over the PM when he died.

After Mori found out Oksana got pregnant after an hookup. He tracked down Shota and kept tabs on him from a distance in case Osamu ever wanted to know about his biological father.

Osamu didn't know exactly how his Mother was connected to the Port Mafia. Because Oksana tried her best to keep Osamu away from the PM at all costs.

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.

After that hookup Shota learned he was gay. Shota always had a crush on Hizashi Yamada one of his best friends but was too scared to say anything because he didn't want to ruin their friendship. Luckily for Shota, Hizashi asked him out later that week. They soon started dating. When they hit 20 years old they got 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.

All the MHA teachers are 8 years older than their season one ages. (Ex. Shota is 38 years old.)

In Chuuya and Osamu's penthouse it's Chuuya and Osamu's day off.

Saturday

Osamu's Pov
I was cuddling on the couch with Chuuya when there was a knock on the door. Much to my distaste Chuuya stopped cuddling with me to answer the door. "Oh! Boss what are you doing here today it's my day off?" Chuuya asked politely. "FUCK off Mori it's Chuuya's day off!" I yelled toward the front door. Chuuya turned his head at me and gave me a disapproving look. Before turned his head back towards Mori. They talked quietly for a few moments before Chuuya let Mori in and closed the door behind him. "Chuuya?! Why did you let him in?! I slightly whined. Chuuya softly sighed. "Osamu he really needs to talk to you about something important...just please hear him out first." Chuuya said softly. I sighed. "Okay." I said sitting up. Chuuya sat next to me while Mori sat in one of the chairs next to the couch.

"Your Mother said she was sorry she couldn't be there for you and she hoped you have been doing well in the future." Mori said. My eyes narrowed. "How did you know my Mother?" I asked seriously. Mori softly smiled a genuine smile something I had never really seen on him before. "We both grew up in the slums and we protected each other as if we were blood siblings. When she was 7 years old and I was 9 years old the Port Mafia found us and took us in. We were trained directly under the Port Mafia Boss he was our mentor. He became very fond of your Mother, Osamu and adopted her as his daughter." Mori said. "My Mother was a part of the Port Mafia why did she never tell me?" I asked confused. "She wanted to protect you from the cruelty of the Port Mafia. She was only 16 years old when she had you. And she didn't want you to suffer the same fate she did." Mori said somber. I realized what he meant. "She committed suicide." I said emotionlessly. "There was more to it. She was sent on a suicide mission by her own adoptive father. Before she went she handed me two letters one addressed to me and the other addressed to you. In case something happened to her on the mission. She successfully completed her mission but she got shot right under her heart and she was bleeding out. She called me explaining her circumstance and plan saying her final words before I heard her gun go off and her phone disconnected. She shot herself in the head so she wouldn't have to die slowly in pain. She loved you very much Osamu. I always blamed your adoptive grandfather for your Mother's death. That's the real reason why I killed him." Mori said. "But you found me randomly after my attempted suicide." I said. "No Osamu it was never random. After Oksana died I read the letter she wrote to me. She told me to look after you for her. But when I got to your house. You were laying on the bathroom floor unconscious. You tried to overdose on sleeping pills. I quickly had to get you back to my doctor's office so I could save you. When you woke up your eyes were so broken looking. I wanted you to live a normal life but you just wanted to find a reason to live. The only way I could watch over you to keep you safe was to make you a part of the Port Mafia and be by my side." Mori said. Chuuya gently squeezed my thigh reassuringly. "Why didn't you go after me when I betrayed the Port Mafia?" I calmly asked. "You think you betrayed the Port Mafia?" Mori asked curiously. "Because I did betray the Port Mafia." I said slightly confused. "Why do you think I sent Oda on that suicide mission?" Mori asked. My eyes widened in realization. "You knew his dying wish would be for me to leave the Port Mafia." I said. "Well I couldn't exactly convince you to leave any other way. You would never believe I wanted the best for you and I have always wanted the best for you Osamu." Mori said handing me a letter it was an off white color probably because of how old it was.

I opened the letter and read it.

Beginning of letter.

"Dear Osamu,

If you are reading this letter it means I'm already dead. I'm sorry that I haven't told you the truth about my past. I just wanted to protect you. Your Father is alive somewhere outside of Yokohama. I don't know his name or where he lives but I'm sure Ogai knows where he is. He wasn't very sneaky about keeping tabs on your Father after he found out I got pregnant. Ogai is such an overprotective brother. Sorry I was ranting. I love you so much Osamu and I hope you're doing well in the future. Please keep living there are so many beautiful things to live for. I want you to find your happiness.

Love, Your Mother Oksana Dazai

Ending of the letter.

I looked up at Mori. "You knew my Father was still alive that's why you didn't call me an orphan when we first met." I said. "Osamu do you want to meet your Father?" Mori asked. I was conflicted but I calmed down when I felt Chuuya's hand on my own gently squeezing it in reassurance. I softly sighed. "Yes I want to meet him." I said calmly.

After traveling outside of Yokohama with Ango's government given permission. Chuuya and I made our way to Musutafu. We were wearing our casual civilian clothes. We followed the address on the back of the photo of what my Father looked like. Once we reached the address I knocked on the door. Soon a teenage boy with purple hair answered the door. "Does Shota Aizawa live here?" I asked calmly. He turned his head back inside. "Dad! Someone is asking for you at the front door!" The boy called. I was a bit surprised at the idea that my biological father had more kids. The boy left and a man took his place at the door. "Yes?" The man said. "You're Shota Aizawa correct?" I asked calmly. "Yes I am is there anything you need?" The man asked suspicious. I looked at the photo one more time before looking back up at him. "I believe you are my biological father." I said as I show him the photo in my hand. His eyes widened in shock before he quickly ushered Chuuya and I inside then he locked the door behind him. "Are you sure I'm your biological father?" Shota asked. "Yep you knocked up my Mother 22 years ago." I said nonchalantly. "Oh my God?! I have a biological child?!" Shota said pacing back and forth. "Fuck I need a drink or 10. Can you two please go into the living room and wait for me." Shota said heading to the alcohol cellar. Chuuya gave me a look and I shrugged my shoulders as we headed to the living room. Once in the living room we sat in a loveseat next to each other. After a few seconds we heard a light set of footsteps. We turned our heads to see a little girl about 7 years old she has bluish off white hair and red eyes with a small horn on the right side of her forehead. She must be my sister. "Who are you?" She softly asked. "Well I'm Osamu and this is Chuuya we're here to talk to your Dad what's your name?" I asked. "My name is Eri. Why does Dad seem surprised by you coming here?" The little girl asked. "He wasn't expecting us." Chuuya said. "Why-" Eri was cut off when Shota walked in. "Eri why don't you go play with Hitoshi while I talk to the guests in private?" Shota asked. "Okay Dad!" Eri said running off. Shota sighed before closing the living room door. He sat in a chair cross from us. "So you have other kids, a teenage boy and a young girl." I pointed out. "Yes my partner and I adopted Hitoshi 2 years ago and Eri 1 year ago." Shota said. "Oh you're married?!" I said. "I have been for 18 years. Anyways you never told me your names." Shota said. "My name is Osamu Dazai and this is my husband Chuuya Nakahara." I said holding Chuuya's hand. "Oh you got married!? I forgot to ask earlier, how is your mother?" Shota said/asked. "She died 8 years ago." I said. "Oh...how did she die?" Shota softly. "It's a bit complicated but the end result was suicide." I said emotionlessly. Everyone just stayed silent for a long moment. "So...how have you been?" Shota asked awkwardly. "Good, you?" I said looking towards Chuuya. "Same." Shota said looking around the room. Chuuya gave me a looked that says our conversation was literally causing him pain. "Well now that has been established. Maybe you can introduce your family." Chuuya said. "Right..." Shota said getting up to walk out the living room door to go get his family. Leaving Chuuya and I alone.
