Ajin (亜人 Ajin, also known as Ajin: Demi-Human) is an anime series that aired from January 15, 2016 to April 9, 2016.
17 years before the story's time, humans who are immortal appear in the war zones of Africa. These humans, known as "Ajin", are high priorities by the government and are captured when found. In the current world, about forty-seven Ajins are known to exist in the different countries. Kei Nagai, a student, is a supposedly normal human being until he gets hit by a truck on a road crossing. Though seemingly killing him, he comes back to life with many "Ajin" characteristics. Now wanted from the government with a price tag on his head, he goes to hiding from the authorities, calling his only trustworthy friend, Kaito, to help him escape humanity's attempts to capture them.
The following weapons were used in the anime series Ajin (2016):
Nambu Model 60

Satou is using a Winchester Model 1897 "Trench Gun" to shoot at SAT operators that had him captured. In all the scenes, the bayonet lug is easily visible.

US Special Forces capture the Ajin in Africa using tranquilizer rifles. It seems that these are the most effective weapons against Ajins, due to their immortality. The tranquilizer rifle has a high similarity to the Dan-inject air rifle.
