it's VERY likely, I would say. mappa did something similar w eren and mikasa at the end of the series, where they created and a extra sequence of them reuniting in the afterlife :") so yes, I think it's very possible that we'll get to see gege's artwork of yuuji and sukuna dancing in the snow animated :"))

as for the songs... EY MEANNNN *gestures vaguely* yeaahhhh. I actually talked about the lyrics of 'yoake no uta' in this ask... CRAZY stuff man. I only looked up the lyrics for aizo a couple months later, and when I did, I thought I read a fan translation for a different song or something lmaoo. it's like they looked through the pages of volume 30 like a cheatsheet before they wrote the lyrics, which made me wonder why aizo (which literally translates to love and hate) did not get the same traction as specialz did, considering that it's also from a villain's pov and has the same mocking and teasing tone to it as the other song... huh.

from you, in 1000 years.
