"Conquering Paradise". One of the war-era background music of "Always Ah" is "Conquering Heaven", which is often used as the background music after someone is sacrificed in war movies. War is a kind of behavior in which collectives, groups, organizations, factions, countries, and governments use violence, attacks, and killings against each other. It is an armed battle conducted by hostile parties to achieve certain political, economic, territorial, and other purposes. Since war is often triggered by politicians rather than soldiers, war is also regarded as an extreme means of politics and diplomacy.
