The Unknown World : Whispers between Realms.

The key to salvation… might also be the end of everything.



When Hikari Mayumi becomes a Soul Traveler, she gains the power to walk between the living and the dead—at the cost of everything she once knew. Hunted by spirits and torn between two powerful guardians, she must uncover ancient secrets, face betrayal, and protect a world that can never remember her. As darkness stirs and love complicates destiny, Hikari’s journey becomes a fight for balance, identity, and survival in a world where not even the dead rest easy.
