As you can see here in the image, we're back to wristband changers, a classic of Sentai. Pressing the lever down on the device causes a train station arrival announcement to play, announcing the transformation. Of particular interest is something rather new to Sentai: the fact that the heroes appear to be able to swap their colors. Presumably, colors confer different abilities, so they can change to suit the occasion. They are identified not by their colors, but by their numbers. The main hero, for example, is Tokkyu #1.
