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

"Let's aim for the strongest, for now." Halbert reincarnates into the world of "The Voice That Beckons to The Abyss (Dungeon)", a legendary erotic RPG known for its sexual violence. In this world, adventurers conquer dungeons to gain rewards, and the common sense is that "HP 0 = being attacked by monsters and suffering a horrific fate," so reducing HP is to be avoided at all costs. However, Halbert, possessing knowledge of the game, takes an unprecedented action—he levels up by reducing his HP and then recovering it, shocking everyone in this world!? (From the outside) Halbert's insane actions cause him to become feared as "a complete maniac"—!? This otherworldly fantasy kicks off as Halbert single-mindedly conquers dungeons and chases after nothing but becoming the "strongest," completely ignoring the erotic aspects of this world!
