Five warriors. Four shamans. One saké-loving demon.

Heian Capital, 1002: As Shrine Miko, Masako loves her job and new home, but her powers have vanished and rumors fly that she'll be forced to leave. When the Crown Prince's consort dies in front of her and a lady-in-waiting disappears without a trace, Masako volunteers for the perilous mission to battle a demon and save the innocent young woman from a gruesome end. But without her powers, she may be destined for the same fate.

Kyoto, 2019: Mina longs to return to the life of a normal college student, but unsettling visions and dreams won't leave her alone. Her mysterious friend Kenji offers to help her search for Masako's journal to find closure, but instead, they find desperate letters Masako wrote a thousand years ago.

Now Mina faces a choice: return to the past to save Masako, or move on with her life and leave the ancient world - and her best friend - behind forever.

The Iron Palace weaves Japanese history and folklore into a captivating tale of courage, strength, and the unbreakable bonds of friendship.
