|This article is about a/an item in Kamen Rider Gaim.|
The Musou Saber Holster (無双セイバーホルスター Musō Seibā Horusutā, lit. "Unrivaled Saber Holster") is a strap for Gaim, Zangetsu, and Bujin Gaim's Ride Wear suits located on the left side of their Sengoku Driver that is used to carry the Musou Saber, making them distinct among the other Armored Riders who lack such a feature.
When Gaim transforms into Kiwami Arms, a second Lockseed Holder replaces his Musou Saber Holster.
- While Kamen Rider Jam used a Musou Saber, his Sengoku Driver didn't come with a holster. Yet, during his transformation, he didn't wield said weapon until it was moved to the fight scene against Gaim and Ryugen, where it is already in its Naginata Mode.
