Isekai Meikyuu no Saishinbu wo Mezasou

One moment Kanami is visiting his sick little sister in the hospital, and the next thing he knows, he wakes up in a dark corridor full of cutthroat warriors and bloodthirsty monsters. Kanami quickly learns that he is in the “labyrinth,” a deadly 100-floor dungeon in a fantasy world–and for those able to reach the deepest level, a wish will be granted. Kanami seems to have received magic powers and a special unnamed skill that kicks in whenever he is overwhelmed, which helps him stabilize but has a disturbing effect on his emotions and mind. After attracting the attention of a mysterious girl, Kanami may have the power he needs to return home to his ailing sister…but at what price? (Source: Seven Seas Entertainment)
