Kuzuya

The protagonist is a nameless middle-aged soldier living the life of a "junker"—scavenging useful items among ruined cities to survive.

He has a tough personality that comes from trying to survive in a dystopic world. He carries a grenade launcher with him and covers himself with a waterproof coat to protect his skin from the toxic rain. For drinking water, his canteen has a water purifier that can purify the rain. He is constantly searching for rarer substances such as cigarettes and alcohol which can be sold at high prices.
