Sengoku Driver

"Lock On!"

- Activation announcement

The Sengoku Driver (戦極（センゴク）ドライバー) is the transformation belt for Armored Riders Gaim (who found it by accident in Helheim Forest), Baron (who got his from Sid), Ryugen (who used his status to convince Sid into "leaving behind" a Driver), Zangetsu, Gridon & Kurokage (who got theirs from Sid), Bravo (who confiscated it from the leader of Team Red Hot after they got it from Sid), and Bujin Gaim. It was invented by Ryoma Sengoku of Yggdrasill Corporation. To transform, the user opens the lock on the Lockseed, then attaches it onto the Drive Bay (ドライブベイ). The Rider then closes the lock to secure it onto the Lock On Arm (ロックオンアーム) and presses the Cutting Blade (カッティングブレード) knife down, which cuts open the Lockseed itself.

The Driver announces the Arms granted by the Lockseed, then a giant mechanical piece of fruit corresponding to the Lockseed used appears from a dimensional opening to the Helheim Forest above the user, and falls on top of their head. Once on the user, the fruit forms the helmet, materializes the suit, and the fruit disassembles to form the chestplate and pauldrons. If the Rider is already in the Helheim Forest, the fruit would just materialise above the Rider from energy in the same color as the Arms armor is in.



Even though all the Riders use a Sengoku Driver which share the same voice, they each have a unique Rider Indicator (ライダーインジケーター) plate on the wearer's left hand side. Each Indicator has different voice tones, as well as different phrases for each Lockseed being used. Each Sengoku Driver shown originally has a blank plate signifying that it is without a user; this is due to the fact that Sengoku Drivers are designed to synch with the first person that uses them, allowing only that individual to transform from thereon. However, a Yggdrasil Corporation employee was shown wearing a blank Driver with no Cutting Edges attached to the Driver, but the significance of this is unclear, but it could be linked to the fact that, with the exception of Zangetsu's, the Sengoku Drivers used by the Riders are prototypes.

Moreover, the Sengoku Driver can be combined with the Genesis Driver. This can be done by replacing the Rider Indicator with the Genesis Driver's Driver Bay with the Energy Lockseed. Currently, it's purposes are still unknown, but it is likely that it will power up the Rider.

When the Cutting Blade is pressed down between one and three times, a Rider can activate a certain ability:
 * Once: The Squash (スカッシュ) function can either initiate the Rider's Rider Kick or power up the Rider form's primary weapon for a finisher.
 * Twice: The Au Lait (オーレ) function gives extra power to the Squash function.
 * Thrice: The Sparking (スパーキング) function converts the user's armor into its fruit form, which can be used as a shield before it reforms back into armor. Gaim's Orange Arms has the potential to rotate at high speeds when using this function, making any attack thrown at it glance off at an awkward angle, leaving the attacker wide open for a counterattack.
