The Lockseed Holder (ロックシードーホルダー Rokkushīdo Horudā), also known simply as the Lock Holder (ロックホルダー Rokku Horudā), is a strap for Gaim's Ride Wear suit located on the right side of his Sengoku Driver. It is used to carry Lockseeds, making him distinct among the other Armored Riders who lack such a feature. It carries Gaim's three standard Lockseeds (Orange, Pine, and Ichigo).
A second Lockseed Holder appears on the left side of Gaim's belt when he transforms into Kiwami Arms, replacing his Musou Saber Holster. This Lockseed Holder carries his three Energy Lockseeds (Lemon Energy, Cherry Energy, and Peach Energy).
The Lockseed Holder is retained by Gaim when his form is corrupted into Gaim Yami, holding his corrupted Dark Orange Lockseed as well as the Pine and Ichigo Lockseeds.
