Rosebound

In the year 5864, Johann Heimbrodt, a wandering mercenary stuck with DIRAC Corp., is approached by an opulent man with a promise of moving up in the world. A simple assignment: slaughter a prestigious family of Bloodphantoms known as the Rozenvojeras. His target, Vladimirella Rovenvojera, seems to evade all sense of decorum—and deathblows—as she effortlessly throws out insults and attacks. Johann, unable to trap Vladimirella into a corner, must find another way to ensnare her before she—and his promotion along with her—can escape.
