An osmium bullet in Phase 100.
|Type||Large caliber bullet|
An osmium bullet (オスミウム弾 Osumiumu Dan?) is a bullet made with the element osmium. The ones used by Zazie were large caliber Magnum revolver bullets with titanium nitride jackets. Unlike a conventional bullet, the tips were slightly recessed. Because they are made with osmium, which is very dense and hard and thus difficult to work with, the bullets are very expensive, each one costing more than Lyuben's salary. The benefit is that they have extremely high penetrating power and thus could not be blocked by Rakan's Bullet Pierce.
