I, Toru Shiina, a high school boy, found that a dungeon portal has been created in a my dorm room closet. Inside, the dungeon is as vast as a video game, and when I reached the bottom, under a large tree in the heart of the dungeon, my eyes widened in surprise. Because my younger sister, A-chan, who had died in an accident when we were children and whose body was never found, was sleeping there under the tree. From that day on, A-chan and I became masters of the dungeon in the closet, and we watched over the dungeon's growth. Today, I will go into the dungeon once again, to see my sister who is supposed to be dead. I'm still not sure what might be waiting for me there. This is a story of joy and misfortune, about trying to capture some happiness. (Source: MF Bunko J, translated)

"In this world, levels are absolute, and the weak are deprived of everything. I was once like that..." This is a world where dangerous monsters roam the land and adventurers make their living by defeating them. With level as the symbol of absolute power, those with the higher levels gained wealth and fame while those with the lower levels exploited others further beneath them. The protagonist, Alca, was called a "corpse scrapper" because of his "Unable to gain experience" skill, which prevented his level from rising, making him the lowest in society. Under such circumstances, he obtained the "Abyss Armor," a suit of armor of calamity. This armor makes him able to use "Level Drain," which allows him to absorb the level of the person he kills! "With this power, all those who stand in my way will be..." Alca, who now has obtained "Level Drain," begins to increase his fame and abilities as an adventurer by absorbing the levels of both humans and monsters alike. But before his path, dragons, the strongest species in the world, as well as adventurers of the natural disaster class, of which there are only a few in the world known. stand in his way. However, even they are nothing but stepping stones for him. This is a heroic tale of a jet-black knight, once despised as the lowest of lowest, who now takes from those above and grows to become the most powerful being in the world.
