Noir Starga, the third son of a minor noble family, is about to lose his only job prospect when he discovers the Great Sage's skill, an ability that lets him consult an oracle at the cost of crippling headaches. The oracle leads him to a hidden dungeon where the legendary adventurer Olivia Servant, chained for two centuries, grants him three unique editor skills: Create, Bestow, and Edit. The catch is that activating them drains massive LP, which Noir can only replenish through pleasurable experiences, entangling him with his childhood friend Emma Brightness and a growing circle of heroines as he climbs the adventurer ranks.
