First and foremost, the core of this item is the existence of the series Kamen Rider Black RX itself. For those who watched it in real-time back then, the Sunriser was not just a mere prop, but the very embodiment of the longing to ”transform.” The value lies in the fact that such an iconic belt has reappeared not as a simple reissue, but as a remake. By adding modern technology and interpretation rather than just reproducing old memories as they were, it has been sublimated into an ”experience that feels even more vivid than those days.”

What makes this Sunriser interesting is that it integrates the charms of two toys that existed in the past. Elements from items with different personalities—the ”Action Control” and the ”Glowing Transformation Belt”—have been combined into one, making the density of play incredibly high. The gimmick where the left and right circles rotate while emitting light, combined with the glow of the internal mechanics, instantly boosts visual satisfaction. That unique radiance when activated in a dark place has a powerful impact, as if a transformation scene from the show has been captured exactly as it was.

One of the greatest features of this belt is the mechanism that responds to ”movement.” The design—where you wear the included Wrist Bit and perform a transformation pose for the belt to recognize it, triggering linked sound and light—sets it apart from toys where you simply press a button. By having your own actions serve as a direct trigger, play instantly turns into an ”experience.” Furthermore, the sequence where holding your hand over it after transforming triggers the Revolcane sound effect doesn't just stop at ”finishing the transformation,” but naturally expands the imaginative battle scenario beyond that.

The sound production is also very substantial. In addition to the transformation sounds, impressive sound effects such as the ”RX Kick” and the de-transformation sound are included, making scenes pop into your head every time you operate it. Also noteworthy is that it supports form changes like Roborider and Biorider. Since dedicated sounds are prepared for each, the configuration allows you to enjoy multiple forms with a single belt. You can feel the ingenuity everywhere, aimed not just at reproduction but at expanding the range of play.

When you actually hold it in your hands, this Sunriser possesses a level of perfection that cannot be contained by the term ”role-play toy” alone. Because multiple elements—light, sound, and motion recognition—are integrated, a feeling as if you are actually transforming arises naturally. While you can enjoy displaying it, it is an item whose true value is demonstrated by actually moving it. There are new discoveries every time you touch it, driving an impulse to ”want to try that pose one more time.”
