Sagitta is a strain of Animus parasite with a peculiar arrow shape. Upon finding a suitable host soul, it impales itself through the soul, extending its long barbs to ensure it stays put.

Sagitta is shown to exhibit superficial changes to the host's appearance including arrow shaped markings across the body, spiral shaped irises and arrow shaped pupils, and complete replacement of the teeth and nails with sharp, arrow shaped versions of them.

Ironically, as the parasite impales itself upon the soul, a curious change to the host's body is they are seemingly immune to such wounds. While not exactly elastic, the host's tissue becomes supple yet extremely durable, unable to be torn, cut or punctured. Bones, while still feeling and having the properties of a normal bone, can endure great deals of physical force exerted to them, and instead of breaking, somehow magically bend as more force is applied to them.
