Arifureta: From Commonplace to World's Strongest (Manga) Vol. 4

Along with their new rabbit-eared companion, Hajime and Yue are ready to challenge one of the world's most perilous dungeons: the labyrinth of Miledi Reisen. As one of the ancient Liberators, Miledi boasted tremendous power, and her sadistic, trap-riddled lair won't go down easy. Inside its confines, Hajime and company find themselves unable to use any of their magic--but he won't back down from the challenge. No matter what stands in his way, Hajime will fight his way back home to Earth!
