The Hidden Dungeon Only I Can Enter

Noir Starga, a noble titleholder, is at the bottom of the social hierarchy due to his circumstances. He possesses a rare ability to communicate with the Great Sage, who grants him answers to any question. This unique ability leads Noir to the Hero Academy, where he hopes to improve his strength and secure a better place in society. There, he discovers a hidden dungeon, where he meets Olivia Servant, a captive woman who gives him powerful skills, but with a life-threatening caveat: each use of his powers reduces his life points.
