Within this battlefield is a cat. Arthur Rain is a mercenary and skilled sniper who is feared as the “Wild Hunt”. As he prepares for another day of sniping, a black cat appears before him. A cat that seemed like a stray who had taken up residence on the battlefield, happily playing with an empty bullet cartridge like it was a toy. This is the story of one man and one animal living in a deadly battlefield, trying to make the days a little more lively.

この戦場には猫がいる。その狙撃の腕前から“ワイルドハント”と恐れられる傭兵、アーサー・レイン。今日もまた狙撃の準備を行う彼の目の前に、1匹の黒猫が現れた。どうやら戦場に住み着いた野良らしい。空薬莢をおもちゃにして楽しそうに遊んでいる。「…少しだけ、このおかしな生き物を観察してみるか」死地に生きる1匹と1人の、少しほっこりな戦場デイズ。
