Karen is the last survivor of the Thorn family and humanity's only S-Class mecha pilot, hiding her identity to honor her mother's dying wish for a quiet life. She marries Ryder, a debt-ridden A-Class pilot, and quietly funds his career and his family for two years.
When Ryder rises on her money, he dumps her for a B-Class pilot and leaves her with nothing. Karen stops hiding. She reveals her combat training, claws back every asset, and digs into the couple's past — uncovering the monster tide that framed her family and killed her parents. With a five-star beast breaking the barrier, she reactivates her Phoenix mecha to hold the line and take back her rank.
