I just watched the first episode of Gunjou no Magmel subbed. It was great as far as I'm concerned. Magmel is a new continent that rose out of the Pacific Ocean like 4 x the size of Australia. People and nations flocked there to get rich and exploit it. I assume the guy that I saw on this episode is the main character. He's a search and rescue guy but is super strong and fast and has tech for weapons and assistance. I recommend at least watching the first episode since this one is so unique from what I just finished watching.
