My Girlfriend Is the Final Boss

Ten years from now, the world ends. The prophecy is clear: The Endbringer will rise, marked by the Voidsong. And the one who loves her most will be the only one strong enough to stop her. Kael Ardyn learns that the girl he loves, his girlfriend, his anchor, his reason for becoming a hero is destined to become that Endbringer. He decides to fight fate itself. What Kael doesn’t know is that Aria already has been. Long before the prophecy reaches him, Aria Vale has lived with fragments of her future. Nightmares she can’t wake from, blackouts filled with ruin, glimpses of herself standing alone after everything is gone. She knows what Voidsong becomes. She knows what she becomes. And she knows that the closer she holds Kael, the closer she comes to destroying the world. Aria’s power, Voidsong, is ancient and forbidden, evolving through stages that trade humanity for strength. It feeds on fear, grief, and loss—and every time she uses it to protect Kael, it pulls her closer to the Endbringer she’s desperate not to become. Kael’s power is no kinder. Through Emotion Sync, his strength evolves based on emotional bonds. The deeper the connection, the stronger the reflection. And his strongest bond—by far—is with Aria. As her power grows darker, his grows stronger. They are bound in a cruel feedback loop: Her power stabilizes near him. His power blooms beside her. And fate tightens its grip the more they refuse to let go. The prophecy claims love will give Kael the strength to kill her. But the prophecy is wrong. The Endbringer does not emerge because of love. She emerges because of its loss. In the true inaccessible future, Aria does not become a monster because Kael chooses to strike her down. She becomes one because he dies. His death is the trigger. Her grief is the catalyst. Voidsong’s final evolution is born from the moment she loses the one person who made her human. The world believes Kael must be strong enough to kill her. In truth, the world needs him to survive. Kael doesn’t know this. Aria suspects it—and quietly begins making impossible choices to prevent it. She distances herself. She hides her fear. She commits morally gray acts in the hope that breaking their bond might weaken the future before it fully forms. But every step she takes away from him pushes her closer to becoming exactly what the prophecy fears. This is not a story about heroes and villains. It is a story about two people burdened with powers that evolve through love, trapped in a future where staying together may doom the world… and losing each other might end it.
