Villain System: Activated> Alignment: Chaotic EvilObjective: Obey the plot, serve the empire, die like a good villain.Yeah, no thanks.I woke up as Dorian Valen—sadistic noble, arsonist, war criminal, mid-tier villain with a face everyone wants to stab.

“Um, are you really Mashin?”

The boy knelt down and asked with a trembling voice. At this, the Nanomachine attached to his cerebrum realized it had been misunderstood.
