This is an isekai (go to another world) (reincarnated) short story and manga. I´ve read Volumes 1-11. Believe that so far have 12.5 volumes.
Positive is the fact that it focuses on the skills learned, artifacts looted or gotten and does not prolong incessantly the fights, quests, etc. The eating of the main character Rou, for skills, gluttony, etc. takes about half the volumes, about 10-15 is the sexual conquests, prima noctis (both male and female elfs for instance) of his captives, hot baths fetish and need to make money and become rich.
Negatives. Holy war isn't really necessary or believable (around volume 9) Why do all the nations come together under the Holy Empire to fight against main character and his Parabellum group. Double standard, main character Rou protects women and children, but cannibalizes ugly women and eats anything and everything possible (humans, monsters, enemies, artifacts, weapons, rocks, etc.) Doesn't let his elders have rape encounters with human women, because he monopolizes them all, etc.
Drawings and illustrations could be a lot better. No maps to help with the quests and better understanding of the story. Food and gluttony centered. Because it is a journal type story of the life of a mutated goblin, story so far is about a year and a half in "real-time". Most translations (especially those from russian and not original japanese) are terrible.
