This is not Shinobu's worm punishment, but is actually Mitsuri's one, she makes Tanjiro and Giyu have kids 😭. Nezuko has eaten a demon, and for that Giyu has also sacrificed his own life, so he has to do a punishment or commit seppuku he doesn't know which way to go. Your going to have Mitsuri's punishment ;-; Don't mind the voice it was random
