In Japan's warring states period, the village of Saika is home to a group of independent mercenaries with extremely powerful weapons. But when an unidentified army supernaturally resilient soldiers attack, the Saika may be faced with more than even they can handle.
The age is now one of chaos;
 bloodshed leading to ever more bloodshed.
العصر في حالة فوضى الآن، وتؤدّي إراقة
الدّماء إلى مزيد من إراقة الدّماء
und das Land verfiel in Unordnung,
während Blut mit Blut vergolten wurde.
Pour le monde,
È un'era di caos, dove le stragi portano ad altre stragi.
A era é de caos, onde derramamento de sangue
resulta em mais derramamento de sangue.
Воцарилась эпоха хаоса,
и кровопролитию нет конца.
