After many trials, the Hero has reached his destination: the throne room of the Demon King, where he hopes to end the war between the Demon and Human realms once and for all. What he finds, however, is not at all what he expected: the 'king' of the Demons is a woman, and a bouncy one at that - what's more, rather than fighting, she wishes to engage him in dialogue! She explains that he was never expected to succeed in his mission, because the war is perpetuated by parties in the human world who profit from it every day. Swayed by her arguments, he makes a pact with her to work toward peace for both their worlds. Together, they will better the lives of their people and create a world where war is no longer needed to ensure prosperity - despite those who would shed blood to keep the status quo.
