A custom Savage piloted by Sagara Sousuke in an underground AS combat league. It's actually a lower spec diesel engined Rk-91, as opposed to the way more common gas turbine powered Rk-92. Sousuke has it painted to emulate the colors of the Arx-7 arbalest, and nicknames the unit "Crossbow" as it's "good, but it's no arbalest".
