Karate Survivor in Another World manga volume 1 features story by Yazin and art by Takahito Kobayashi.

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!
