Weighing 120 lb. (approx. 60 kg) unloaded, the 30 mm, single-shot breech loader cannon uses various types of shells, including depleted uranium with silver for piercing armored targets and incendiary napalm rounds for destroying large groups of opponents both on land and in the air. Carrying this weapon, the vampirically-enhanced Seras serves perfectly as long-range fire support. Her immense strength also allows her to use the weapon while moving; sometimes, especially in the manga, she wields it with an extraordinary ease, even firing over her shoulder.
