Aizen X Y/n - Blog Posts

Hey, can you write about Aizen being a girl dad and doting on her. Y/n and Aizen being parents and enjoying that parenthood together. The daughter looking like y/n but having similar wits as him.

Ohhh it's been a long time since I wrote Papa Aizen! Thank you for your request!

CW: this is SFW! Also human Aizen because I've been in a mood for him lately!

At his core, Aizen was a man of science and logic. He knew how genetics worked, he understood it at the cellular and molecular level.

Yet it amazed him every time he looked at his daughter, how she was a spitting image of you. The way her eyes lit up when he picked her up from daycare to the way she smiled or even cried – it was, much to Aizen's dismay, uncanny.

Yet even with your looks, your slight mannerisms (she was her own person after all – that much Aizen and you instilled into her), she was a clever little girl. It amused him and unnerved you.

Children are like sponges – he wonders what else she'll learn from him.

Today though, was just a simple grocery store run. You had asked Aizen to pick up a few things for dinner and your daughter politely asked if she could come along. Manners were important to him, and it is again, of no surprise, she learned them as well.

"Oh Aizen-san, your daughter is so well-behaved!"

"I never met such a polite child!"

He would smile and nod, thanking them for the compliments, but he always wondered about her - was she like him? Perceiving the world around them a bit differently from the rest? He noticed she would be a bit more protective of you, almost like he was.

Strangers would joke and tease how she was a “mini” version of you, but close friends and family knew she was more like her dear father.

Nonetheless, a grocery run with his daughter would provide some interesting insights. She was still small enough to sit in the cart, but he asked her (politely of course) if she wanted to sit. She nodded her head, and she became queen of the cart.

“Do you remember what mommy asked for?” Aizen quizzed her. The way she bit her lip and thought about it was so eerily like you.

“Green onions!”

“Excellent, what else?”

“Hmm… toys?”

Aizen chuckled, "no, I don't think that's what mommy asked for."

She pouted, but without missing a beat, "but mommy loves playing with me."

Interesting, Aizen thought, how she was using a fact about you to cover her own interests. An amused look crossed his face. "If I remember what mommy said, she asked for mirin."

His daughter opened her mouth to say something, but nodded along, clapping her hands. As he pushed the cart down the aisles, he would stop to look at different items. Without fail, he would see, in the corner of his eye, his daughter picking up an item with great interest, and trying carefully to place it into the cart without him knowing.

And now they were in the bakery, looking at the selection of cakes, pastries and other baked goods on display.

"Daddy, up please!" She pleaded, stretching her arms overhead. And who was Aizen to say no? He carefully picked her up out of the cart and steadied her. Her eyes lit up at the assortment of goods that laid in front of her.

Aizen walked slightly away, near the fresh breads and feigned interest in the variety of loaves. He watched his daughter pick up a pre-sliced cake piece and again, place it carefully in the cart.

Once she was successful, she quickly turned around and spotted him immediately. Rushing towards him, she clung to Aizen's leg. Without even a thought, he picked her up, "did you see anything interesting?" He asked her.

She shook her head, placing it on his shoulder. He could see she was getting tired.

"Then lets go home then, mommy must be waiting for us."

Aizen placed her back in the cart, but also began removing some of the items she had placed before. He could see her slowly blink, struggling to stay awake. He gently patted her head as she began to doze.

But he kept one item in the cart - the slice of cake. It happened to be your favourite. He wondered if it was because of you, or if she had also begun to enjoy the taste as well. Curiosity filled his mind as to what was going through his daughter's mind when she was picking up each item.

But Aizen knew better than to wake a sleeping toddler. Although his daughter was well-mannered, she was still a child, and he knew better than to start a tantrum.

But she groggily woke up as soon as they reached home.

"Welcome home!" You beamed, as you picked your daughter from Aizen. "And did you get everything I asked for?" You asked her.

She nodded her head vigorously, "we did! I also got you a bunch of stuff, mommy!"

"You did? Why don't you show me?"

Aizen couldn't help but smile at the sight of his daughter leading you to the kitchen as he carried the groceries. The three of you began to unpack, but your daughter was beginning to huff.

"Daddy," she whined, "where's all the stuff?"

"I'm not sure I know what you're talking about." Aizen lied, wondering what she would do.

She blinked at him - as if your eyes were staring directly at him. He felt a smidge of guilt but held on to his curiosity.

"I got mommy pretty things." She said, her voice cracking, eyes watering instantly.

You looked at the two of them confused, "oh, you don't have to get me anything!" You cooed at her, picking her up. You nuzzled her cheek to comfort her, as she clung on to you tight.

"Did you mean this?" Aizen asked his daughter, holding the cake slice.

She shot up in your arms, "yes! Mommy's favourite!" She giggled.

"You got this for me?" You asked her, "you're too sweet." You smiled, kissing her on her forehead. “Let’s have it together after dinner.”

Aizen had a slight smirk on his face as he continued to observe his daughter. She seemed pleased with your suggestion.

Dinner came with a show, as you watched with amusement as your daughter tried to shove her food on to Aizen’s plate.

“That’s not very nice dear, food is for eating, not playing with.” You chided her. She pouted as she looked at her mess.

“She’s trying to get me full.” Aizen chuckled. “More cake for the two of you.” He smiled, catching on to what she was doing.

Your daughter’s mouth hung open; eyes wide as she got caught, “nuh uh! Daddy you don’t like cake.”

“I do like cake.” Aizen replied calmly, a smile on his face as he wondered where his daughter would go with this. “I especially like the cake mommy makes.”

“Me too! Mommy makes the best cakes.”

You couldn’t help but smile, “you two flatter me so much, how about we make a cake on the weekend?”

Your daughter nodded her head enthusiastically, clapping.

Once dinner was put away and your daughter cleaned up, you brought out the small slice of cake. You cut a piece for your daughter, feeding it to her, but she only took two bites. Aizen himself, didn’t want much of it. You were also full, leaving the remainder for tomorrow. Although your daughter was full, she was excited, “mommy, when is the weekend?”

“A few more days.” You gently patted her head.

“Can it come sooner? I wanna bake a cake with you and daddy now.” She whined.

It was then Aizen realized, the slice of cake wasn’t what she wanted, but to have the three of you make a cake together. He looked at his daughter, who stared back to him, a small smile on her face.

How amusing, Aizen thought, thinking of what other traps and ideas she would have in store for the two of you.

Thanks for your request! I had an idea based off something that happened between my little sister and dad when she was a toddler, but it was hard to write (and I can't see Aizen at WalMart HAHAHA).
