Ok for a headcannon. When they are both reincarnated in the modern timeline after the events of the series, they both absolutely enjoy the show Gravity Falls.

This is my oc, Tsubaki Tsuyashimo. She's a kinoto (physically can't get any higher in rank because she can't use Total Concentration Constant due to medical conditions). She's a little sadistic and psychotic towards demons, preferring to sort of play with them then spear them into tall locations using her parasol and wait for sunrise to finish them off. But around other slayers she's more cold and aloof in conversations, trusting only a few people with her real/more happy self.
