A/N: Hey guys! So a week or two ago I went and saw Big Hero 6 and fell in love with both Hiro and Tadashi, and not to mention Cass, so I figured I should start one of the many ideas I've thought of for this fandom. I don't own Big Hero 6, enjoy!


Birth

"Aw, sis!" Cass cooed, smiling as he stroked her brand-new nephew's warm, pink cheek. "He's too cute!"

"Isn't he?" Mrs. Naomi Hamada smiled, holding her new baby in her arms. "What do you say, honey?"

Mr. Kyo Hamada looked up from his phone while sitting in the chair across from his wife's hospital bed. He faked a smile and nodded, hoping that would be enough to answer whatever it was she was asking. He hadn't been paying attention.

"What're you gonna name him, sis?" Cass asked, almost squealing when the new baby grabbed her finger with his tiny palm.

"We're calling him Tadashi." Naomi smiled a tired smile and a yawn. Childbirth was no quick and easy process after all.

"Oh, that's so perfect!" Cass giggled, happy as her sister finally pushed the baby into her arms. "Hey there little Tadashi."

The tiny newborn in her arms made a little groan as he himself was tired. He opened his tiny eyes and smiled an little smile at his Aunt Cass.

Cass gasped happily as she hugged the baby closer. "Aw, he smiled at me! The little cutie, I love him already!"

Naomi rolled her eyes as her sister continued to screech happily with Tadashi in her arms. The nurse soon walked in with a birth certificate in hand, ready to be filled out.

She handed it to Mrs. Hamada hurriedly, before rushing over to tell Cass she needed to calm down if she wanted to keep holding the baby.

"Oh, whoops. Sorry." Cass chuckled sheepishly, before sitting in the chair next to her brother-in-law with Tadashi still in her arms.

She looked over at Kyo and smiled. "Do you want to hold him? He is your baby after all."

Kyo looked at the still smiling baby in Cass's arms, before shaking his head. "He looks pretty content with you, Cass."

The new aunt only nodded, somewhat surprised, but too in love with her nephew to question it.

Mrs. Hamada then called over her husband, much to his discontent. "Kyo, come here."

Kyo sneered, before standing from his chair and walking to his wife's bedside. "Yes?"

"Give this back to the nurse, please." Naomi said, handing the filled-out document to her husband.

Kyo sighed, before walking off to find the nurse.

Cass then stood up and walked over to her sister. "Is Kyo okay?"

Naomi grimaced and shrugged. "Who knows? That man's been acting distant since the day he found out I was pregnant."

"Hm," Cass said, holding Tadashi close until remembering that it wasn't her baby. "Oh! Here, this is yours."

She giggled as she moved Tadashi back into his mother's hold. As soon as she did, however, the newborn began to whine.

"Uh oh." Cass smirked, tickling Tadashi's tummy before giggling to the baby with mommy-talk. "Is someone a tired little thing? Aw, baby needs a nap?"

Tadashi soon calmed down, again grabbing his aunt's finger happily.

"Geez, Cass. Five years younger than me and you seem like a better mom." Naomi rolled her eyes again, annoyed that her sister couldn't seem to leave the baby alone.

"Are you kidding?" Cass laughed heartily. "I couldn't change a diaper if I tried. Let alone make baby formula. No, I'd better just stick to being the aunt he can vent to if mommy yells at him."

Naomi sighed. "Alright, no diaper duty for you then."

The two sisters chuckled, as Tadashi began to stir again.

"I think somebody needs some mommy love, sis." Cass smiled at the baby.

"Yep." Naomi nodded, before leaning down and reluctantly kissing the baby in her arms.

Cass smiled and stroked the baby's cheek again. "So are you guys moving into that little house mom and dad lived in before they had us?"

"Yeah, I guess so."

"You got pretty lucky, huh?" Cass smiled, sitting in the chair next to the bed and playing with her nephew's toes, making him giggle.

Naomi stirred, annoyed at that statement. "Lucky? I just had a baby at eighteen years old…"

"Oh, no. I meant, you at least have a house already. So you don't have to worry about payments on it or anything."

Naomi nodded, before sighing. "I suppose."

"And since Kyo agreed to take our family name like our parents made him, they'll probably help you guys if you need it."

"They only made him do that to carry on the family name. I mean, we got married barely half a year ago. Of course they'd have requests."

"Well, you can just play the guilt card and say it's their fault they didn't have any sons." The little sister chuckled. "If Kyo hadn't agreed to do it, then the family name wouldn't be continued."

"What if you got married?" Naomi smirked at her little sister.

At this, Cass laughed. "Are you kidding? I can barely take care of myself. Anyway, I'm only thirteen. I doubt they had me and my romance life in mind when you were getting married."

"Yep…" Naomi chuckled, sighing as she looked down at the baby.

Cass did as well, holding one of the baby's warm and tiny hands with two of her fingers. "He's too cute, sis."

"Yep…" Naomi repeated, looking down warily at the stirring child in her arms.

Oh no…she thought, knowing she had made a mistake.
