The fragile peace between humans, vampires, and werewolves begins to crack. As Ema's immunity becomes the epicenter of escalating conflicts, she's drawn deeper into a clandestine war where alliances shift like shadows.

A covert faction emerges - monsters who believe Ema's blood could tip the balance of power. With Taiga at her side, she stalks the spectral corridors of Tokyo's underbelly, following haunting whispers of a ritual that could awaken something ancient and catastrophic.

As moonlight collides with neon, Ema faces a harrowing truth: to protect those she cares about, she may need to embrace the very darkness she's resisted. Her bond with Taiga intensifies - but can love endure when destinies - and lifetimes - are at stake?
