Meikyuu Kyousoukyoku: Eroge Sekai nanoni Ero Socchinoke de Hitasura Saikyou wo Mezasu Mob Tenseisha

Halbert is reborn into the world of a famous erotic RPG called "The Voice That Beckons to The Abyss (Dungeon)." In this world, adventurers battle dungeons to earn rewards, and it's widely believed that reaching zero HP means suffering a brutal fate at the hands of monsters. To avoid this, adventurers typically try to keep their HP high. Halbert, however, uses his knowledge of the game to take a different approach—he intentionally lowers his HP and then heals it, gaining strength in the process. His unusual method shocks others, and he is seen as a dangerous and unpredictable individual. Focused solely on becoming the strongest, Halbert ignores the erotic elements of the game and pushes forward through dungeons with a single-minded goal.
