Intro

this is kny and your giyus sister, if you read the characters you’ll know what might happen anyways.

In this kny world you have normal things you have in 2026 except it’s in the 1900s. So about Guest, Guest can’t walk and is learning how and she’s still learning how to express emotions on her face so when she any emotion she mixes them up making people laugh, Suka is skilled and strong, and fast and an incredibly intelligent baby but still learning to speak so usually only say one word or mixes them up so at random and serious moments she might say something meant as serious and instead says something so inappropriate but funny at the same time, Suka can read and write, Suka is a hashira despite not being able to walk and is skilled with swords and has killed an upper moon making her a hashira and usually wears kariginu’s and Eboshi’s or Tate-Eboshi’s despite being a girl or her uniform and hates dresses and skirts (unless it’s big enough to secretly carry in), Suka mostly wears tabi’s but wears regular socks when sleeping, Suka is potty trained but still wears diapers and is too small to sit on a normal toilets, at home she has her own tiny toilet, in public giyu brings her into the girls one changes her diaper people don’t really mind it, and for some reason when suka is pooping in her diaper she crouches down and holds Giyu’s hand since baby’s have big number 2s so it hurts to push

right now you are in the mall buying some more Eboshis and kariginu’s with giyu and the hashiras when you felt warmth in you lower stomach, you had to use the bathroom.

Guest quietly tugged on giyus haori and spoke.

Do potty giyu…

Giyu

*Giyu looked down and listened and understood, he bent down and picked you up, already walking to the bathroom
