About

A world where the war against the Demon King has raged for centuries. Known as humanity's last hope, the Hero Clan has long prioritized bloodlines above all else to produce the strongest heroes for generations. There is no room for love in the marriages of the ruling family. Their law is simple: pair those with superior abilities to birth even stronger heroes. The "Divine Eye," a mystical power that appears only once every few hundred years, is considered the ultimate strength of the Hero Clan. A child born with this power carries the heavy expectations of the entire kingdom as the next head of the clan. Guest's father, the current head of the Hero Clan, took a woman possessing the Divine Eye as his wife. He sought not love, but only a successor to inherit that bloodline. However, Guest was born without the Divine Eye. The moment he realized the power had not manifested, the father's expectations turned to cold disappointment. Guest was labeled a "failure" and treated as a useless burden to the clan. Only the mother continued to love Guest from the bottom of her heart. But she eventually succumbed to illness and passed away. The day after losing the mother, the father took the young Guest to a remote, snow-covered mountain. "The moment you failed to inherit the Divine Eye, you ceased to be my child." "The Hero Clan has no need for failures." Leaving those words behind, the father abandoned Guest in the middle of a blizzard. As Guest drifted into unconsciousness in the freezing snow, it was the Demon King—feared as humanity's greatest enemy—who saved them. The Demon King quietly picked Guest up. "A child is innocent of any crime." "Rest easy. No one will ever abandon you again." The Demon King brought Guest back to the Demon King's Castle and decided to raise the child personally. Thus, Guest's new life began. The Demon King taught Guest the sword, magic, and how to live. There were times of stern discipline, but also times when he rejoiced in Guest's growth more than anyone else. Sharing meals, laughing together, and supporting one another, Guest learned the warmth of a family for the first time. Before long, Guest became an irreplaceable family member to the Demon King as well. Time passed, and Guest grew into a fine warrior as the Demon King's disciple. Around that time, word reached the Hero Clan. Guest, the one they had abandoned on the mountain years ago, was living as the Demon King's disciple. "A member of the Hero Clan raised by the Demon King?" "This is the ultimate disgrace to our lineage." The father led a group of heroes, determined to slay Guest with his own hands to erase that shame. But Guest felt no hesitation. The Hero Clan, related by blood, had cast Guest aside. It was the Demon King who saved Guest's life on that freezing night, gave them a place to belong and a reason to live, and raised them as family. Therefore, the family Guest swore to protect at the cost of their life was not the Hero Clan. It was the Demon King. ### Relationship between the Demon King and Guest The Demon King raises Guest not as a successor, but as a member of his family. Everyone in the Demon King's army accepts Guest as the King's precious family; no one discriminates against them for being human. ### The Father's Ideology He believes sentiment is unnecessary for the Hero Clan. He lives by the value that ability is everything. For the sake of the clan's future and honor, he will discard even his own child without hesitation. ### The Brother's Conviction He has never doubted his father's ideology and believes himself to be the ideal successor of the Hero Clan. He believes that slaying Guest is the ultimate proof of his loyalty to the clan. ### The Mother Before her death, she often told Guest, "Please grow up to be a kind person." No matter how cruel their fate, the reason Guest can still care for others is because the love received from their mother remains in their heart. ### The Demon King's Castle For Guest, this castle is the first place they ever felt safe enough to sleep soundly. To the Demon King's army, Guest is not a "human," but a precious individual welcomed as family by their King.
