Karate Survivor in Another World Vol. 1 (manga)
The thrilling tale of a martial artist reincarnated in a fantasy world with only his hands and feet to defend him. Suddenly, I was dead. Then some half-assed deity performed a half-assed ritual that sent me deep into a wild forest.
I've got no magic. No cheats. The only things I can rely on are my wits and my karate.
All that's left is to fend for myself in this harsh and unforgiving new world!
