"Elek/Ice/Devil Steam!"

―Special attack announcement^[src]

The Valve Rotator Steam Blade (バルブ回転 スチームブレード, Barubu Kaiten Suchīmu Burēdo) is a weapon wielded by users of the Transteam Gun and Nebulasteam Gun. It combines with the Transteam Gun to form the Steam Rifle (スチームライフル, Suchīmu Raifuru) or the Nebulasteam Gun to form the Nebulasteam Rifle (ネビュラスチームライフル, Nebyura Suchīmu Raifuru).

Design

• Overheat Blade (オーバーヒートブレード, Ōbāhīto Burēdo) - The yellow bladed portion of the Steam Blade. An inbuilt heating unit can change its surface temperature, allowing the user to melt objects upon contact.
• Steam Change Valve (スチームチェンジバルブ, Suchīmu Chenji Barubu ) - The red valve in the middle of the Steam Blade, it allows the user to change between Ice, Elek or Devil Steam for attacks.
• Tri-Attack Trigger (トリアタックトリガー, Toriatakku Torigā) - The trigger of the Steam Blade. After changing the Steam Change Valve to the desired steam attack, pressing the Tri-Attack Trigger will activate the finisher.
• Transtock Grip (トランストックグリップ, Toransutokku Gurippu) - The grip of the Steam Blade, it seperates from the rest of the weapon when combining with the Nebula/Transteam Gun. It is excellent at absorbing impacts during attacks. When combined with the Nebula/Transteam Gun, it serves as a counterweight so as to prevent the weapon's trajectory from being affected by the weight of the front blade.
• End Shot Muzzle (エンドショットマズル, Endo Shotto Mazuru) - The gun muzzle of the Nebula/Steam Rifle, it is capable of shooting out bombardment bullets called Trans Burette (エンドショットマズル, Toransu Byuretto) or special light bullets containing various types of steam, inflicting great damage upon the target.
• Long Snipe Scope (ロングスナイプスコープ, Rongu Sunaipu Sukōpu) - The scope mounted on the Nebula/Transteam Gun, it has an inbuilt computer system which measures distance to the target, wind speed, air density, etc. and uses it to pinpoint accurate trajectory and perform automatic correction of sighting if necessary. Using the Long Snipe Scope, it is possible to snipe up to 3km with pinpoint precision.

Functionality

The Steam Blade splits at the handle and its front half (blade part) connects to the front of the Transteam Gun/Nebulasteam Gun, while the rear half (handle part) connects to the back of the Gun to form the Steam Rifle. The connected front half serves as the barrel with its blade being bayonet for close combat while the rear part serves as the stock.

The Steam Blade's valve turns in both Blade Mode and Rifle Mode to change attack types.

Notes

• Interestingly, the pipes on the Steam Blade and Transteam Gun match.
  • Additionally, the pipes are colored after 3 common colors of electric wires in real-life (Red, Green, Yellow).
• Unlike the Transteam Gun, the Steam Blade only has a full-size prop.
  • In order to fit with DX versions of the Transteam & Nebulasteam Guns, the DX Steam Blade is considerably smaller than its in-show prop.
