Then I was unexpectedly summoned by a minor, forgettable noble household to deliver a sealed item for an unusually high payment.

As I made contact with the noble, a calm, foreign voice commanded me to kill, and my body moved without control. A sudden surge of unnatural power erupted from me, killing the noble instantly. When I regained awareness, the sealed item had vanished, replaced by a mysterious book in my hands, as chaos broke out around him.
