Neo Green Life, also know as the NGL or N.G.L. NGL was a isolationist self-governed neo-Luddite country with the former population of 2.17 million people and was part of the Mitene Union, along with East-Gorteau and 4 other countries.
The people of NGL lived in harmony with nature and rejected any form of modern technology while preventing anything created from synthetic materials entering their country.
Chimera Ants are one of the many animals and magical beasts that could be found in the country along with dozens of other exotic animals.
Gyro will be relevant soon. Love that there are people who still hope in Togashi!

The history of the country isn't really explored, but most were probably just primitivists and just had a dislike for industry and modern society. The NGL has some parallels with Jim Jones' The People's Church, so maybe there were also religious and socialist motivations.
Volumes always release whwn Togashi starts releasing the next batch of chapters. It is probably a contract thing. Shueisha might refuse to print unless the manga continues to make sure Togashi doesn't slack off too long.
