Ore dake Haireru Kakushi Dungeon

Despite his noble title, Noir Starga is at the bottom of the social hierarchy. Because of this, his fellow nobles oppress him and treat him like garbage. However, he possesses a rare yet powerful ability to communicate with the Great Sage, an oracle who grants Noir the answer to absolutely anything. After failing to secure a job as a librarian, Noir decides to join the Hero Academy. He knows he must become stronger to enter the institution. The Great Sage advises him to explore a hidden dungeon deep within the mountains. There, Noir meets Olivia Servant, a beautiful yet enchained maiden trapped within the labyrinth. Olivia bestows upon Noir a set of ridiculously powerful skills that grants him virtually total control over reality. Naturally, there is a catch—every time Noir attempts to use his powers, his life points decrease, putting his life at risk. To replenish his energy, he must give in to worldly pleasures such as kissing his childhood friend! With his newfound powers, Noir begins his journey as a student in the Hero Academy, meeting new acquaintances and helping them through the dire situations ahead. Noir is the son of a minor noble with very little to his name other than a job offer—which is canceled before he can even start his first day. He does possess one rare trait, though: the magical ability to consult with a great sage, even if using the skill gives him terrible headaches! Unsure of what his future holds, he accesses the sage for advice on how to move forward and is directed to a secret dungeon filled with rare beasts and magical items. It is here that Noir will train, compiling experience and wealth, until hes powerful enough to change his fate.
