This item has been opened. The Cast-Off Rider Series (commonly known as COR) is an action figure series featuring characters from the TV movie "Kamen Rider Kabuto." These figures have movable joints allowing for the recreation of action scenes from the show. However, the most significant feature is the ability to blow off the figure's armored parts, "Masked Armor," with a single switch (this is called "cast-off"). This allows you to instantly switch between the heavily armored style immediately after transformation, the first form "Masked Form," and the agile second form "Rider Form," suitable for high-speed combat. You can fully enjoy the two-stage transformation, a key characteristic of the Kamen Riders in "Kabuto." The armor parts included with each figure in the series are also interchangeable, and by collecting the lineup, you can recreate various armed states from the show, as well as original, never-before-seen forms, allowing for countless combinations. It was a massive hit when released, and it's a legendary figure series that quickly sold out in many shops. Don't miss this rare opportunity to acquire this essential item when discussing the history of Heisei Kamen Rider action figures.
