Katyusha

In their eternal struggle against all of that which they perceive to be evil, the heavens, driven by their own ideals, bestowed upon the Sacred Nyrheimian Kingdom a supernatural power, known as "the Energy of the Gods." They ordered the people of the kingdom to use the power they were given to convert the rest of the world to their own religion, Jafnaorism, a religion centred around a set of ethical principles, according to which a person possesses human rights only insofar as that they are a fully morally good person. The Nyrheimians were given a time period of three years to master the Energy of the Gods, before they are to declare war against every country that would refuse to convert to Jafnaorism. While the Jafnaorists prepare for their upcoming crusade, two seemingly ordinary schoolgirls from a faraway country also experience their own personal battles against evil in their day-to-day lives. However, by some unknown process, they, too, develop the Energy of the Gods at the climax of their conflicts with their enemies. Guided by this power, as well as their own senses of justice, Shirosakura Hakutenshi and Arumariya Angeletta continue their fights against evil, which very quickly escalate to a scale far grander than the personal struggles they have encountered thus far.
