Sabito lives as a soul, wandering around. He likes to watch the final selection exams, because he died during his 7th day there, and wants to know who survives. Neither humans nor Demons see him. Sabito was serious young man who believed that all of his actions should be becoming of a man. Sakonji took in Sabito and Makomo after they were both orphaned, where he met Giyu, training them until they became strong enough to enter Final Selection to potentially become Demon Slayers.
