Mamonogurai no Boukensha: Ore dake Mamono wo Kuratte Tsuyoku Naru

Nobody wants "Grubby Forager" Rudd on their adventuring team. His nickname—and his stench—come from his constant treks into the Noxious Labyrinth to gather medicinal herbs, a job he survives only thanks to his status immunity skill. When he's finally recruited as a party porter, things seem to be looking up... Until a deadly dungeon monster appears and his fake allies use him as bait before abandoning him! Wounded, destitute, and barely surviving the attack, Rudd breaks a forbidden taboo to stay alive: eating monsters. But the more he devours, the more power he gains, kicking off a thrilling, adventurous gourmet fantasy! (Source: Square Enix)
