The story is set in a world embroiled by war between Humans and Demons. The Humans' greatest warrior known as the Hero invades the castle of the Demon King, leader of the Demons who is actually a Queen, as he is determined to vanquish her. However, instead of fighting back, the Demon Queen proposes an alliance with the Hero. She explains how a sudden end to the war can bring further chaos to the world as the Humans, once united to stand against their common enemies, would eventually begin fighting among themselves, with similar issues already occurring in the Demon Realm. Convinced by her words, the Hero joins forces with the Queen and together they execute a plan to bring prosperity and a lasting peace to both Humans and Demons alike.
