Synopsis
LIFE AFTER DEATH

Kaito Ukei was destined for greatness in his new world, landing himself the role of a hero and defeating the evil sorceress alongside a band of noble adventurers. When he's double crossed, though, and brutally murdered by his former allies, something inside him snaps. Death brings Kaito neither peace nor salvation. Rather, it instills in him a singular desire—to squeeze the life out of his blasted betrayers in the cruellest manner possible...! The strange twist of fate that gives him a second chance in the world with all his memories intact provides opportunity to do just that, and so begins his quest to stalk and torture the members of his former party in the bloodiest, unholiest, most sadistic ways imaginable!
