When Kanbara Kanata is whisked away from his mundane life to a world of adventure, he inadvertently offends the all-powerful being who brought him there. As punishment, he is sent to the bottom of the most dangerous dungeon without a single special power or ability! He is sure that he's a goner until he meets a lich girl named Lunaère--an undead powerhouse who hates humans, but grudgingly decides to assist him all the same. With Lunaère's help, Kanata may just grow into someone truly incredible!
