When a rift tore open in the world and monsters poured out, humanity braced for the demon lord Rukimedes' return. Yet, even the gravity of this crisis cannot stop the antics of the straight-man hero Alba Frühling and the sadistic soldier Ross. Ross, trapped in a plane between two worlds by Januar Ein's magic, finds the demon lord napping and looking far too comfortable in his confinement. Meanwhile, Alba, back in prison once again, is sidelined by his eccentric companion's hijinks. Though separated, Ross and Alba persist in their efforts to prevent the demon lord's resurgence, unaware that a ghost from Ross' past may jeopardize their quest's success.
