The day had come and Y/N was on a bed in the Butterfly estate, holding Haganezuka's arm harshly while their children trembled outside the door in fear. A soft high pitched cry was heard and the young boys rushed into the room to see a tiny being with long eyelashes curled up against their mother's neck. Their father smiles,

"Well, now we have a little daughter and a sister. Her name is Akane."

Kou jumped up and down happily while Hiro and Shiro tried to imitate him. 2 years went by pretty fast and Y/N very well knew how Haganezuka acts with a girl in the family. He'd shoo away anyone that tried being close with her, always getting dragged away by his wife for being too protective. Hiro and Shiro played with her and Kou would usually take care of them while their parents were busy. For a 5-year-old boy, he had a great sense of responsibility.

"Kou, Aka-chan wants milk."

"Mik! Mik! Me want!"

The three brothers went jelly from the cute gesture, quickly getting some warm milk for her. She was the princess of the family. When dinner came about, Y/N returned and threw something into Haganezuka's face. Everyone laughed at the smack except her. He took the object and looked at it, face paling.

"Yeah. I'm pregnant again."

Kou whined,

"Papa, mama, why do I have a lot of siblings?!"

Haganezuka laughed wholesomely,

"Our love for each other is too much!"

Kou 'pukes' at how his father was overly affectionate with their mother. Hiro and Shiro just giggled along with Akane who had food spilled everywhere. A couple of months passed and the family followed their parents to the Butterfly estate. Shinobu sighed as she did an ultrasound,

"You guys really are bunnies. Congratulations. Another set of twins."

...

...

"TWINS?!"

Haganezuka beamed,

"Girls? Boys?"

"Both. A boy and a girl."

"Heaven's by my side."

Y/N growled,

"Hell's by my side."

Another journey of pain and joy, the birth of more children. Kanroji, who was by Y/N's side the entire time during the ultrasound, tiredly sighs.

"Haganezuka, if you guys ever want to hanky panky again, pray that you won't have quadruplets. I suggest you get some pills or else the entire village will become the Haganezuka village."

"That doesn't sound bad."

His wife hit him hard on the shoulder, making him wince in pain. On their way back, Haganezuka was on cloud nine thinking of buying another house to expand their current house. It's going to cost a fortune but if his children can live comfortably, he doesn't mind spending. Y/N had a meeting with Ubuyashiki about this, which she thought of retiring. He told her that he wants to keep her in case of an outbreak and that she can stay at the swordsmith village if she agrees to be a standby. She'd still receive pay but it will be slightly lower than before. From the start of her assignment to protect the village, she eventually became a mother of the village. 3 years went by fast and it was the peak of demon activities. Y/N was caring for the younger twins that seemed to learn to waddle while she let her older children roam independently. Tanjiro, a young boy who has the potential of being a demon slayer that will change history, entered their house because he had broken Haganezuka's blade again. Haganezuka blasted angrily at the boy because of the broken blade and also because his 5-year-old daughter looked so comfortable on Tanjiro's lap.

"TANJIRO! IF I SEE YOU DO ANYTHING INAPPROPRIATE TO MY PRINCESS I'LL KILL YOU."

Y/N appeared from the corner, rubbing her belly with the twins by her side.

"Oh, Hello Y/N! Hello Sora and Haru! How's - Wait, Y/N are you pregnant?!"

"*Sigh* Yep, again. Because that sorry ass over there does not know how to keep his hands off and agree to buy pills for me."

"I-I see... I guess what Shinobu said about the Haganezuka family was true..."

"WHATCHA SAY TANJIRO BRAT?!"

The Haganezuka family was indeed a family of bunnies.
