Vasilissa

Vasilissa (処刑者) is Galopoula's Trigger used by Gatlin.

Appearance
Vasilissa takes the form of a backpack-like device with mechanical arms extended from it. The device has pins inserted into them. When the pins are inserted into stubs of limbs, the limb sprouts large guns.

Abilities
This Trigger renders losing arms pointless as the user can regenerate it as a more useful firearm. The firepower is strong enough that it was able to dent the wall of guarding the Expedition ship, despite being deflected. The arms are also powerful, being able to pin down Tachikawa.

Trivia

 * Vasilissa (βασίλισσα, vasilissa) is the Greek word for "queen".
