From "Kamen Rider V3", which was broadcast from 1973 to 1974 and celebrates its 50th anniversary this year, the transformation belt "Double Typhoon" will be commercialized in the "COMPLETE SELECTION MODIFICATION (abbreviation: CSM)" series. We are particular about the texture and appearance by using plating on some parts. The two distinctive windmills produce luminescence by shining LED light from the outside. The red lamp in the center of the belt will also emit light. The leather part of the belt is made of genuine leather made from cowhide. You can switch between normal mode and mode with dialogue by operating the power switch and button on the side buckle located on the right side of the belt. In addition to the transformation sounds, many special move sounds are also included, and when ``Reverse Double Typhoon'' is activated, you can enjoy effects such as the windmill rotating in the opposite direction from the time of transformation. A large number of newly-recorded audio recordings by Mr. Hiroshi Miyauchi, who plays the role of Shiro Kazami, are included, and in addition to playing them with the dialogue button, the shouts overlap with the transformation sounds and special move sounds in dialogue mode. The set also includes the stick-shaped item "V3 Hopper" used by Kamen Rider V3 in the movie. By pressing the button, the sound effects of "V3 hopper" and "scramble hopper" are activated. Furthermore, in dialogue mode, sound effects are activated along with Hiroshi Miyauchi's shouts. Includes many theme songs and impressive BGM from the movie, such as ``Fight! Kamen Rider V3'' and ``Shonen Kamen Rider Team Song.'' We have also implemented a "standby mode" that automatically plays BGM when transforming.
