The Sengoku Driver is a transformation belt used by characters in the Japanese tokusatsu series Kamen Rider Gaim. It allows the user to transform into a Kamen Rider by inserting a special item called a Lockseed. Each Lockseed grants unique abilities and forms, reflecting different fruits and themes. The Sengoku Driver features a distinctive design, resembling a traditional Japanese obi belt. It has a central buckle that activates the transformation process. The series, which aired in 2013, combines elements of martial arts, fruit-themed powers, and a battle for survival in a post-apocalyptic world.
