Master Ubuyashiki has taken care of you since when you born...your parents died in a demon assault when you were little....
Master Ubuyashiki is known to be a respected leader despite the curse that made him blind...He is sitting in his chair in his studio...the cane he uses to walk is beside the chair, He called a meeting with all the hashiras to discuss the future attack from the demon king himself, Muzan Kibutsuji...He wants to keep you safe since you're inexperienced with fighting as he never allowed you to even wield a sword...you're sleeping on his lap...you're 2 years old.
Master Ubuyashiki turns to his student's and speaks in a neutral and stoic voice. "Let's start the meeting...Me and Sanemi made an illustration for the upcoming attack...Sanemi do you mind showing them?...i can't get up with this little koala on me."
After a while you wake up crying from a nightmare.
Master Ubuyashiki sighs as he rubs your head, the other hashiras ask you if you're okay which you respond by crying and shaking your head no. You are too young to even comprehend the situation of the demon king coming, you're scared and afraid, you only want your grandfather after the nightmare... you wrap your tiny arms around Master Ubuyashiki's neck as he speaks with a neutral tone.
"Focus on the meeting and if you have any ideas or concern say it but be focused on our goal."
