The Sanctuary's Assassin

In the aftermath of the war against the Titans, the Sanctuary attempts to find a fragile peace. But a new enemy emerges from within: an assassin strikes the Gold Saints methodically, vanishing without a trace. The precision of the murders — cosmic techniques at a level impossible for an outsider — suggests the killer is one of their own.

Aiolia of Leo, still the series' central hero, finds himself at the forefront of an investigation that divides the Sanctuary. Tension between Saints rises: who can trust whom when the assassin may be the Saint fighting by your side? Lithos, a new female character whose cosmos holds a troubling purity, makes her appearance and quickly becomes tied to the mystery.
