1st Shift/Armaments & AbilitiesEditBeing more advanced than its predecessor, the Silent Zephyrus boasts superior agility and has 6 shield bits alongside its offensive bits. The controls for the bits alone are difficult enough to deal with, which surprised Cecilia when confronted with the unit the first time, since she took a long time to master her own (in the novel she mentions that M has mastered some unique abilities of the bits Cecilia herself hadn't yet mastered until the Cannonball Fast battle).
In addition to the bits, it is equipped with a high-energy rifle that has a bayonet attachment.
- Star Breaker: a gun capable of using both BT energy and live ammunition.
- Zephyrus may be a reference to Zephyrus who is the Greek god of west winds.
- From a full body view, it seems to resemble a butterfly.
