Jailed in Guillé Prison and awaiting execution, Watt finds himself rescued by the Royal Knights, led by their captain and Watt’s old friend, Carome.

As a Diviner, the most powerful class of Mechsteel, Inferno Cerberus boasts a power unlike anything they’ve ever seen. Watt and the Royal Knights are locked in a fiery battle for survival! Afterward, an uneasy calm hangs in the air as Legalisbelm seems poised to reach its conclusion. As Watt quickly finds out, however, this battle for the throne is far from over. With the shadowy tendrils of a plot sinister beyond imagination now creeping ever closer, does this old knight have what it takes to make it out alive?
