Re:Monster

After a tragic death, he wakes up to find himself reincarnated as a feeble and weak goblin named, Gobrou. However, due to his extremely unique ability "absorption", he is able to get stronger the more he feeds. He finds himself evolving at an astonishing rate and in no time becomes the leader of his community! In another world where only the strong survive, along with competent fellow goblins and friends, Gobrou becomes one of the most powerful goblins in this fun and exciting fantasy!!
