The Rousing Gun Garren Rouzer (醒銃ギャレンラウザー Seijū Gyaren Rauzā) is Garren’s primary armament, which is a hi-tech gun that serves as a weapon for combat and storage unit for Rouse Cards. It has a built-in 'rousing' technology, which enables Garren to "rouse" the sealed Undead's power to utilize personally.
After activating Jack Form, the Garren Rouser gains an enhancement in the form of a bayonet-like blade on the barrel below the muzzle, as a way for the Rouzer to be used for close-range attacks. This form is called Empowered-Type (強化型 Kyōka-gata). As Garren's non-canon usage of King Form didn't affect the armor's design like Kazumi's, the King Rouzer-like weapon possessed the same form of storage as the Garren Rouzer.
