Lucy juggles her double life, catering to powerful men while keeping her identity hidden from classmates and professors. Each man she encounters offers both opportunity and risk-some are protective, some dangerous, and others obsessive. One day, she falls for someone who doesn't want to own her, but save her. But in this world, no one leaves unscathed. Her past, present, and future collide as enemies rise from within her own client list, and secrets threaten to explode.

Yuki Konno was abandoned as a baby and found deep within a mysterious forest in Japan. Raised in a cold and cruel orphanage, Yuki grew up being bullied, ostracized, and labeled "strange" for one reason-he constantly talked to someone no one else could see. That someone was Ame no Kuro, a powerful, invisible guardian only Yuki could perceive. Unknown to the world, Ame no Kuro holds the key to Yuki's forgotten past... and the fate of multiple collapsing realms. When a strange dungeon gate opens near the forest of his origin, Yuki is pulled into a brutal new reality. There, under life-or-death pressure, he awakens a powerful system known as the Ascension Protocol-a forgotten mechanism from a long-dead realm of gods and monsters. He becomes a Realmwalker, a being capable of traversing and influencing entire dimensions. As he rises from a powerless orphan to a feared and respected warrior, Yuki faces corrupted Guardians, rogue hunters, evolving dungeons, and an ancient war reawakening in secret. The world thinks he's weak-but hidden within him is the legacy of a godslayer, a Realmbreaker who once shattered the sky itself. But power has a price-and Yuki must decide: Will he remain human? Or become something else entirely to protect the only family he has ever known?
