When the assassins destroyed Archduke Ferdinand's sarcophagus, they actually left behind several broken walking sticks at the scene. How could assassins who managed to produce alchemical explosives not have access to firearms?

Charles, in his deliberate manner, flicked his finger, and the Blood Rose materialized at his hand. He grasped the hilt of the magic stabbing sword and said calmly yet confidently, "Dear Ms. Leopard Woman, please resist with all your might."
