Y/n had to take a break for at least three days to make sure she took care of Katsuya. The other twin however, became too protective of his twin sister, that he almost didn't sleep at night just to guard her. It seemed cute at first, but everytime Y/n saw Katsurin drifting off, she could only force the little boy to go to sleep.

After a few days, Katsuya was finally free to go home. Of course, after a few debates on whether they are going to their home, or Katsuki's home. They decided that they'd stay in their own home for now, since then, Katsuki could only visit everyday.

It shouldn't bother Y/n. But it does. To the fullest.

How did it suddenly come down to this?

Y/n had to go back to work the next day. Now, she was just preparing dinner for them. The twins are playing in the living room but are taking it slow for Katsuya's sake.

There were knocks on the door that caught all three's attention. Y/n walks up to the door and opens it, revealing Izuku still in his hero costume.

"Oh, nii-chan!" Y/n said with wide eyes.

Izuku smiled and handed her a bag full of sweets and mumbles a "For the kids," and then enters the room.

"Uncle Deku!"
"Izuku!"

The twins shouted and jumped on their uncle.

"Hello my favorite twins in the world! How are you both?!"

"I'm great!" Katsuya says with a smile.

"I'm working on my quirk now, uncle! I have a strong quirk, I can easily become a hero!!" Katsurin bragged.

"I know! You have such a strong quirk!" Izuku praised.

"Oi, don't praise him too much or else his ego will burst! It's fine to compliment him from time to time, but not too much!" Y/n scolded from the kitchen.

"And why not, mama?!"

"Do you wanna end up like your selfish, egocentric, narcissistic, big headed like your dad?" Y/n rolled her eyes.

"Eh?! Papa was like that?! I don't wanna be like papa!"

"Y/n!" Izuku called in a threatening tone. He went to the kitchen, Katsuya still in his arms.

"Don't be like that to Kacchan. You're making the kids hate him. He's still their dad,"

Y/n just rolled her eyes.

"Mama, Uncle Deku, when will Katsuya get her quirk?" Katsurin asked, small explosions sparked on his small palms.

The two adults could only look at each other.

"Actually, sweetheart..."

"Did you know that uncle Deku is actually quirkless?" Izuku said with a smile, eyes basically disappearing as he looked at the girl he was carrying.

"Huh?! Mama told us before but I'm not believing! You have a super strong quirk!!!" Katsurin said, eyes wide.

"Yes, well.. Not much people know about this. But do you know All Might?"

"Yes! I'm  a big fan of him! It's just sad that he had to retire before we were even born," Katsurin replied.

"Yeah, well, before he retired, he gave me his quirk. It's super hard to explain, but that's how I got my quirk! If it weren't for All Might, I wouldn't have a quirk, study in UA, fight so many villains, and become the number 1 hero!" Izuku gleefuly said.

The twins looked at each other, and then looked back at Izuku with stars in their eyes.

"That's so cool!"

"That probably explains why there's a possibility that Katsuya might be quirkless.. But we'll go to a doctor tomorrow, I'll ask Shoto if I can go home early."

"Mama, we don't have to do that. I'm fine with being quirkless!" Katsuya said with a smile.

"No no. We're gonna get you checked up with a doctor. You should be getting your quirk at this age, at the same time as Katsurin."

"I won't let Katsuya be quirkless! Uncle Deku, you can give your quirk to her, right?!" Katsurin turned to his uncle.

"I could, but before she can use it, it requires hell of a training,"

"Oh no. I've seen you clean up a whole beach," Y/n said as she continues to set the dinner table. "It was hell. And Katsuya is too young! And, not to mention, your uncle Izuku isn't looking for someone to take his quirk yet! All Might only did that because he's old!"

"Y/n-chan... If All Might heard that..."

"So? I'm telling the truth! Uncle Izuku won't be transferring his quirk to Katsuya because it's dangerous, okay?"

"Okay mama." Katsuya simply replied.

"No! That's not fair! She has to have a quirk!" Katsurin argued.

"Don't worry, kid. We'll find another way, if Katsuya-chan here is really quirkless." Izuku comforted him.

"Well you better, uncle Deku! I want me and Katsuya to be pro heroes, just like mama and you!"

"I'll make sure to find a way. But I better be going," Izuku said as he walked towards the door.

"What? You're not staying?" Y/n asked.

"Yeah. I have to work overtime for an entire week. I better go and have some rest. I'll see you two again,and I'm gonna bring lots of presents!" Izuku patted both Katsuya and Katsurin's heads and opened the door. As soon as he opened it, he was surprised to see another person outside, just about to knock.

"Ghh--! Deku?! What are you doing here?!"
