The transformation sound is the same as the previously released TV Power DX Kingstone, which was re-released as part of Kamen Rider Black Sun's crowdfunding campaign. After transformation, pressing the ACT button again will play additional sound effects, which includes Shadow Moon's foot steps and the Shadow Punch attack.
Just like the TV Power DX Kingstone, the belt will automatically operate depending on what is happening onscreen. By pressing the TV POWER button on the transformation belt, and playing the included DVD (which is episode 47 of the Kamen Rider BLACK TV series), the center of the Shadow Charger will glow green and rotate according to what is happening on the video. Lastly, pressing the FLA button will cause the front white light of the item to light up. This Premium Bandai web exclusive item cost 9,350 yen and is set for an April 2023 release. Pre-orders will end on November 26th.
