The Rousing Gun Larc Rouzer (醒銃 ラルクラウザー Seijū Raruku Rauzā) is a bow gun-type card reader exclusively for Kamen Rider Larc developed based on Garren Rouzer. The effect of Vesta (ベスタ Besuta) is demonstrated by rousing the Rouse Card above the barrel. Its initial AP is 5500.
The bow at the tip called as Basilicus Bow (バシリクスボウ Bashirikusu Bou) can be opened and closed. By closing, it becomes a cutting edge for short-range battle that cuts off enemies with high frequency vibration and high heat radiation. By opening it, Larc can respond to long-range battles as a bow gun that fires a powerful light arrow.
Scanning the Mighty Ray Rouse Card initiates the Ray Bullet (レイバレット Rei Baretto) finishing attack.
