Elara is an ordinary worker in a magical city, struggling to get by. Hoping for a little comfort, she buys a small black creature for just two copper coins, thinking it’s nothing more than a cute pet.
But the creature is actually the Bone-Crowned Abyssal Beast, an ancient and feared Lord of the Abyss.
From the shadows, it silently eliminates every danger around her, becoming an unseen guardian. Yet as others grow close to Elara, its jealousy begins to surface.
To stay by her side, the beast takes human form—a dangerously attractive but obsessive man—willing to destroy anything that threatens her. The only risk is that Ella might discover the truth behind the “pet” who loves her too much.
