As reported previously this impressive item features an IR sensor that lets the Laser Blade detect your hand as you slide ir up the blade to “charge” it in the same way that Gavan does for his Gavan Dynamic attack. Whilst doing so you can press a button on the hilt to the either the series BGM, or rapidly press it to recreate sound effects from the show. These images also confirm the inclusion of the fantastic set of display hands to hold the Laser blade. See the promo video below with the legendary actor who played Gavan, Mr. Kenji Ohba, demonstrating these wonderful features.
The Tamashii Lab Laser Blade is set for January 2017 release for a whopping 16,200 yen.
