ARC OVERVIEW
After Miyu's tragic sacrifice and her spirit's final message, Melinda Gordon is pulled into a darker, deeper mystery: an organization called Horizon once experimented on gifted children—Miyu being one of them.
But Miyu reveals one crucial truth before fading:
More children were used.
More are still alive.
And the project isn't over.
Melinda's new mission is to uncover where these children are, who is still hunting them, and how to protect them before they become the next victims of "Project Echo."
This arc shifts the tone from a single tragedy to a broader supernatural conspiracy.
