Each Guts Hyper Key is richly equipped with sounds such as transformation sounds, shouts, special move sounds, and color timer sounds that represent each Ultraman, and you can play the sounds in sequence by briefly pressing the button on the main unit. As a first-time feature for this set, it also includes the roars of the monsters that fought fiercely with each Ultraman. Also, by holding down the button, the state switches to three modes, and the content of the sounds changes as follows: 1. Hyper Key Mode (Transformation Play Mode) This mode is specialized for role-playing play just like in the show. When you press the button, the Guts Hyper Key's activation sound will play, and by setting it in the "DX Guts Sparklence (sold separately)", the transformation sequence sounds of each Ultraman will be activated. Also, after the transformation play, operating the trigger of the Guts Sparklence will play in-show sounds such as technique effect sounds. 2. Sound Mode This mode allows you to play the transformation sounds, shouts, and special move sounds built into the Guts Hyper Key in sequence each time you press the button. 3. Monster Picture Book Mode This mode allows you to play the roars of the monsters that fought against the Ultraman of that key each time you press the button. A total of 8 keys are planned to include over 70 types of roars. Each Guts Hyper Key also works with the separately sold "DX Circle Arms" to enjoy special move play. Furthermore, the package specifications have also been upgraded, and the product will be commercialized with a special design with a door that allows for cool display even when left in the box. This is a permanent preservation item to give to fans of the Ultraman series.

I was able to confirm that all the sounds play when I press the buttons. The contents are clean, but the box has folds and scratches from when it was opened.
