Peerless Dismantler
Musou no Kaitaishi / 無双の解体師

Dungeons appear across the world, drawing explorers in search of resources found only inside them. Sakuto Kurose enters the dungeons to find the Elixir, a cure-all medicine that could save his childhood friend, who has an incurable disease. When his comrades decide he is no longer useful in battle, Sakuto is dismissed. With danger in both the dungeons and the real world, he faces monsters and malicious people in a battle to pursue the medicine his friend needs.
