Level Up Just By Eating

The young man named Kehma who was summoned to another world, and the useless Goddess Laura whose only strong point is having huge breasts. Gaining a cheat skill that absorbs the abilities of what he eats, he enjoys his new adventurous life eating delicious monsters and playing with the easy to handle Goddess, all while becoming wildly overpowered/peerless in this otherworld fantasy. — Description from novelcodex.org
