Y/n is a new, young, demon, already number 2 in the uppermoons, knocking everyone below Kokushibo down a rank (Which means Daki and Gyutaro are no longer part of it). However, when introduced, everyone melts into a platonic love and possession over them, even Lord Muzan himself. Everything Y/n does is seen as adorable and even important, and it takes them almost everything in their willpower to not just cuddle you forever
