The Hidden Dungeon Only I Can Enter

俺だけ入れる隠しダンジョン

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.
