Re:Monster

Tomokui Kanata has suffered an early death, but his adventures are far from over. He is reborn into a fantastical world of swords and magic-- as a lowly goblin. Not content to let this stop him, the now-renamed “Rou” uses his new physical abilities and his old memories to plow ahead in a world where consuming other creatures allows him to acquire their strengths and powers.

Super sadly this is the only one of its kind
