Toko was assigned to clean the back shed. Moving aside the stack of journals Yoshiteru liked to read, she pulled out a whole bunch of boxes out of the way so she could clean the way back. "Why do we have so much junk.. AHHHH!"
Toko found herself falling into a dark place before crashing, coughing amidst a dust cloud. "Owww... that hurt! Huh?"
She looked around. This wasn't the shed, it looked like a simple bedroom. There was a strange box in the corner. "What the...?
"Nezuko-chan~"
A boy showed up with a bouquet of flowers, but suddenly stopped in his tracks when he saw Toko. "Nezuko... where did you get those weird clothes?"
"It's my uniform, dummy! And what's up with your hair, Yoshiteru? Mom's not gonna like the fact that you dyed it!"
"Dyed... it? Yoshiteru? Um, my name is Zenitsu."
"Zen-" Toko nearly choked. "No... way... GREAT-GRANDPA?!"
"Huh?"
Why was Nezuko calling him that? Wait... maybe that isn't Nezuko at all... is she from the future, his descendant?! But if his descendant looks like Nezuko, then that means...!
Zenitsu's shock caused him to pass out.
"Wait! Great-Grandpa, don't faint! I need your help to get home!"
