The 4-Mode Change Gan Gun Saber (４モード変形ガンガンセイバー Yon Mōdo Henkei Gan Gan Seibā, lit. "Eye Gun Saber") is a sword-like multiform weapon wielded by Kamen Rider Ghost. It made its first appearance in episode 47 of Kamen Rider Drive. It is summoned from either the Ghost Driver or the Eyecon Driver G by Ghost. When summoned by Grateful Damashii, if applicable, the Heroic Eyecon spirits each hold their own main mode of the weapon; even those usually armed with the Sunglasseslasher sometimes instead hold the Gan Gun Saber, such as Himiko wielding Naginata Mode.
