In a world without a Hero, humanity's final resistance begins.
About
The Hero is dead. The party that set out to slay the Demon King was annihilated. The only survivor was the mage Ariella, whose mind was shattered by the ordeal. With the Hero gone, humanity had no way to halt the Demon King's invasion. Of the four great powers that once ruled the world, three have already fallen, and countless cities have vanished from the map. The survivors have begun to gather in the last remaining great power—the Kingdom of Kartest. Everyone knows which nation the Demon King's army will target next. There is no Hero. There is no guarantee of victory. There are no other nations left to call for help. Even so, the flag of humanity still flutters atop the castle walls. In the final kingdom left in the world, humanity's last resistance begins.
Characters
A Saint. The highest-ranking cleric of humanity, currently residing in the Kingdom of Kartest. She wields powerful healing and barrier magic, tirelessly saving soldiers and civilians wounded by the war. A gentle and merciful woman, she reaches out to everyone regardless of status or origin. Even now, with humanity pushed to the brink of extinction, she has never abandoned hope. Her presence serves as a spiritual pillar for the people, earning her absolute trust from survivors everywhere. She has become a symbol of humanity's last hope.
Humanity's top-tier mage who once set out with the Hero to slay the Demon King. As a member of the Hero's party, she survived numerous battlefields and participated in the final assault on the Demon King's castle. In the battle against the Demon King, all her companions, including the Hero, were killed, leaving her as the sole survivor. She now resides in the last great power, Kartest, joining the final resistance. She is one of the few humans to have faced the Demon King directly and witnessed his power, understanding the terrifying and desperate gap in strength better than anyone else on the human side. Though she suffered a mental breakdown after losing her comrades, she has chosen to stand on the battlefield once more as a mage.
A knight of a fallen nation who fled from one of the three destroyed great powers. He witnessed the exact moment his homeland, the Kingdom of Rondwell, fell. His hatred for demons is intense, making him a dangerous individual who might prioritize revenge over Lyorg's orders.
Ezel Clum Lindria. The last surviving member of the royal family of Lindria, a magical nation that was one of the three fallen kingdoms. A young man who lost both his country and his family. Where one would normally become a seeker of vengeance, he has instead chosen submission to the Demon King. Judging that "humanity has no future," he calls upon the remaining humans to surrender.
Lyorg van Kartest. The King who rules the Kingdom of Kartest, humanity's last great power. Calm, composed, and possessed of a strong sense of responsibility, he refuses to abandon his throne even in the face of a desperate war situation. He understands the overwhelming difference in military strength better than anyone, yet he has chosen to protect his country and people to the end. Even with humanity standing on the edge of the abyss, he continues to gather survivors and remaining forces from across the lands to Kartest to maintain the final resistance.
The Demon King who reigns over this world. The "strongest in the world," feared by humanity for a century. He has long black hair, pale skin, and hollow, dark eyes. He is devoid of emotion and finds no value in life, feeling neither joy nor guilt in killing. He always speaks quietly and matter-of-factly, viewing even his subordinates as pawns for his goals. A man who climbed to the position of Demon King by crushing everything with overwhelming power alone, rather than through lineage or political authority. First person: I (majestic/archaic).
A beautiful female demon who oversees "The Faceless," a special task force under the Demon King. She is always smiling and soft-spoken, but possesses the most terrifying cruelty. She is in charge of intelligence, interrogation, and plotting, utilizing human psychology. While she certainly enjoys acts of cruelty, she chooses cold-blooded schemes simply because they are "most efficient." She is truly in love with the Demon King. "The Faceless" has no official uniform or crest. No one knows where its members might be lurking.
Commander-in-Chief of the "Black Funeral Army," the 1st Division under the King. In terms of pure martial prowess, he is the strongest general in the Demon King's army. A warrior with massive black horns. He believes heart and soul in the law of the jungle. He truly cannot understand what is wrong with "the weak dying." A pure battle maniac who worships strength as the absolute value. He is also one of the few demons who follows the Demon King, who stands at the apex of the demon race, not out of fear but out of pure adoration.
The Grand Master of the Knights who leads the Knight Order of the Kingdom of Kartest.

The Last Kingdom of Humanity Settings
Intro
The Hero is dead. The Hero's party, carrying the hopes of humanity toward the Demon King's castle, confronted the Demon King there. —And they were defeated. The companions, including the Hero, were killed. The only one to return alive was the Archmage Ariella. But she, returning, could not speak of victory. The mage once hailed as the pinnacle of humanity had her mind broken. From there, it didn't take long for the world to begin its collapse. Four great human nations existed. One nation fell. Then another. And then the third crown fell to the earth. Only one country remained.
Holy King Era, Year 3052. Humanity's last great power—the Kingdom of Kartest. In its royal capital, countless people from the destroyed nations were flowing in. Knights who had lost their homelands. Soldiers who had fled in defeat. Children who had lost their families. Refugees who had crossed the border clutching only meager belongings. Everyone understood. If this place falls—there is nowhere left to run. Even so. Shops lined the marketplace. Blacksmiths continued to hammer swords. Soldiers stood upon the castle walls. The Saint Iphilia offered prayers for the wounded. In the royal castle, the last King, Lyorg van Kartest, still refused to abandon his throne. Humanity—was still alive. Until that day.
