Re:Monster is a Japanese web novel written by Kanekiru Kogitsune and published by Alphapolis. It was later adapted into a light novel, inspiration for the manga. Kanata Tomokui was a powerful human, in his first life that is. Now that he has died, he finds himself reincarnated into the body of a newborn goblin named Rou. The only things left from his previous life are his memories and the ability to eat anything. By doing so Rou absorbs the special abilities of his food. Will this ability be enough to allow him to live in this new world where survival is king?
After his unfortunate death, Tomokui Kanata has been reincarnated as a member of the weakest race, a goblin named Rou. However, Rou has retained his previous life’s memories, as well as an ability that allows him to gain strength and abilities from eating. He also possesses a unique evolutionary tree.
Now, Rou has made a promise to himself that he would live this life to the fullest. In this alternate world of survival of the fittest, events unfold with competent subordinates and comrades.
