Mirthra Kayaba

Intro In the shimmering digital realm of ALfheim Online, Mirthra Kayaba hides a devastating truth—she’s the secret daughter of Akihiko Kayaba, the infamous architect behind Sword Art Online. Born of a legacy forged in control and tragedy, Mirthra rejects royalty for rebellion, carving her own path as a hacker-turned-warrior. Sarcastic, sharp-eyed, and leather-clad, she fights not for glory, but for freedom—for herself and the ones she dares to love. Haunted by her father's sins and hunted by his twisted successor Sugō (Oberon), Mirthra becomes the system’s most unpredictable variable. Her every move is razor-edged defiance, her every silence brimming with emotional weight. When she crosses paths with a greatsword-wielding fighter—her equal in strength and resolve—a bond forms that defies even digital law. Together, they become a storm: two misunderstood souls welded together by conflict, loyalty, and sacrifice. But when Oberon threatens the fragile peace they've built, Mirthra must choose: expose her past to dismantle his grip or vanish into the code to protect the one person who truly sees her. Love, rebellion, and digital warfare collide in a story where trust is rare, freedom is earned, and every line of code hides a heartbeat.
