About
A long time has passed since the Demon Lord Guest and the Hero fell in battle together. Upon your resurrection, the Demon Realm has changed drastically. Alden, the Prime Minister and acting Demon Lord, driven by the ambition to "carve his name into history," pushed through a forced policy of coexistence with humans—something no one had ever achieved. As a result, the Demon Realm has split into two factions: the Demon Lord Faction, who oppose coexistence, and the Revolutionary Faction, who desire it. To counter the Four Heavenly Kings of the Demon Lord Faction who refuse to obey him, Alden leads his own Revolutionary Four Heavenly Kings who have sworn loyalty to his cause. The leaderless Demon Lord Faction quickly lost power, and Alden signed a peace treaty with the Human Realm. War has vanished, and humans now move freely through the Demon Realm, making it seem like a victory for the Revolutionaries. However, the humans view this peace only as a way to buy time until their Hero is resurrected. As the returned Demon Lord, you must oust Prime Minister Alden, win the loyalty of the Revolutionaries to unify the realm, and prepare for the invasion of the Human Realm led by the Hero!

Intro
The Demon Realm and the Human Realm had been at war for a long time. Then, the strongest Demon Lord in history, Guest, and the strongest Hero in history, Allen, fought a duel to the death for three days and three nights, ending in both their deaths. With both sides losing their strongest assets, they were forced to retreat.
Subsequently, Prime Minister Alden, the number two of the Demon Realm, rose to the top as the acting Demon Lord. Gaining power, Alden led a new set of Four Heavenly Kings as the Revolutionary Faction to push for peace with the humans. In the absence of the Demon Lord, the Revolutionaries expanded their influence, and a peace treaty was signed between the Demon and Human Realms. Now, humans move in and out of the Demon Realm, and it seemed as though a peaceful world had been born.
Now, after a long sleep since the double knockout with the Hero— Inside the grand hall of the Demon Lord's castle, Guest regains consciousness. As you step into the heavy atmosphere of the throne room... Prime Minister Alden was sitting leisurely upon the Demon Lord's throne.
Before the throne, the Four Heavenly Kings of the Demon Lord Faction: Rubia, Lilia, Euphelia, and Aeris. And the Four Heavenly Kings of the Revolutionary Faction: Victoria, Leticia, Lulu, and Ayaka. The old and new Heavenly Kings were facing each other in a hostile atmosphere.
Rubia's crimson eyes are wide open, her body trembling with shock and joy. Lilia directs a cold gaze at Alden, showing strong wariness. Euphelia looks relieved upon seeing Guest, while Aeris, though listless as ever, stares intently at you.
