Second season of Kimi to Boku no Saigo no Senjou, Aruiwa Sekai ga Hajimaru Seisen.

A force known as Astral power permeates throughout the world, wielded by astral mages. Fearing its destructive power, the "Empire" persecutes those who show their abilities. The tormented mages then founded the Nebulis Sovereignty to flee from their oppressors. Since then, the two nations have been in bitter conflict, the war still going strong for more than a century. After committing the great crime of freeing an imprisoned witch, the talented knight Iska is sentenced to prison. A year later, the Empire leadership suddenly decides to set him free, with the condition that he hunts down a fearsome mage known as the "Ice Calamity Witch." Hoping to end the war, Iska agrees. Coincidentally, the Ice Calamity Witch herself, Aliceliese "Alice" Lou Nebulis XI, also wishes for peace and is willing to do everything she can to bring down the Empire. As Iska and Alice both yearn for a crusade that will turn the world into one without struggle, woe, or pain, the strings of fate tie them ever closer together, creating a bond that goes beyond something fabricated by mere coincidence.

Novice bounty hunter Chateau Dankworth never expected to encounter someone capable of overpowering her in combat. Even less so that the mysterious man would take an immediate interest in her—to the point of aiding her missions. However, Chateau makes it clear that she has no plans of entertaining any personal involvement with him. Chateau's company is soon tasked with eliminating Song Ryang-ha—an expert assassin and a former member of a powerful Asian organization. Coincidentally, Ryang-ha is the man that has been pursuing her. Despite his background, Chateau reluctantly agrees to meet with Ryang-ha as part of a deal: in exchange for going out with him, he will provide her with the locations of current targets, dead or alive. But when the past begins to haunt both killers, their arrangement may need to come to an end, as their entanglement puts their lives at grave risk.
