Like other Crossbone Vanguard mobile suits the technology for the Ebirhu-S is derived from the basic XM-01 Den'an Zon. However the Ebirhu-S is not a combat mobile suit and is designed for reconnaissance. To facilitate this role the Ebirhu-S mounts a remote controlled reconnaissance probe on its right shoulder which can be launched and sent to scout ahead of the mobile suit. Also the Ebirhu-S has an additional bank of advanced sensors and cameras built into the left shoulder.

The Ebirhu-S is the smallest and lightest mobile suit used by the Crossbone Vanguard. It also possesses the second slowest acceleration speed and its power generator has the lowest power output. Though it is a reconnaissance mobile suit the Ebirhu-S possesses an astounding amount of weapons, though only two of those weapons are beam weapons, a single beam spray gun and a single beam saber. Its other weapons are a shot lancer with two charges, a four barrel heavy machine gun and four shot claws mounted in the left hand, and a rack of three rocket propelled grenades mounted above the left shoulder.
