Yuriko was the sole survivor of a brutal program - the Omega Program, to be precise - held in the Shiro Sanitarium, a private military firm that seeks to decrease the Empire's reliance on high technology with a literally living weapon. It is unknown what effect the Sanitarium's program had on Yuriko's mental state, though she appears dehumanized. Whatever occurred, Yuriko possesses immense power; not fully understood by science.

It has been reported that Yuriko is capable of levitating infantry and vehicles into the air before ripping them apart with her psionic powers, as well as instantly destroying any aircraft by sending them crashing into the ground.
