In this story, I headcanon that Mo Mo was born in the Taisho era
and joined the Demon Slayer Corps,
becoming the Ice Hashira (or serving alongside Shinobu as a Kinoe swordsman, haha).
#Could an Upper Rank Demon become a swordsman in the Demon Slayer Corps?#
#Mo Mo doesn't want to be human today, either#
