Door-Ju



The Opening and Closing Loading Door-Ju (開閉装填ドア銃) is a firearm weapon wielded by Kamen Rider Drive, resembling Tridoron's driver-side door. It first appears in episode 8.

Like the Handle-Ken, Shinnosuke names this weapon for the car door attachment on the barrel's side, and Mr. Belt disapproves of his lackluster choice. When the Door-Ju is summoned, it comes from the front portion of Tridoron's hollow section.

A replica of the Door-Ju is also wielded by the Imitation Drive, with this version shooting out water.

In the future, when the Drive system becomes corrupted, the Door-Ju ended up in the possession of Eiji Tomari's Shinnosuke's son in the future, using it to fend himself against Future Roidmudes.

In episode 42, the Door-Ju was stolen from Drive and used by Gold Drive during their first battle with each other.

Usage
The Door-Ju can fire several shots before needing to be reloaded, which is easily accomplished by opening and closing the door, as well as project a car door-like energy shield. If the door is open while being fired, the Door-Ju will give an error announcement of "Open Door" (半ドア) and misfire. Once reloaded, it will say "Charge" (チャージ). If the door is opened and closed multiple times while there is still ammo, the bullets will become much stronger. During his fight against the Open Roidmude, Drive's performance with the Door-Ju was disabled by the Roidmude constantly opening the weapon's door until it became jammed ajar.

In terms of Drive's main forms, Type Technic has the most compatibility with the Door-Ju due to its near pin-perfect precision fitting with the long range combat nature of this weapon.

Finishing attacks
The Door-Ju's Full Throttle finisher PerfecShot (パーフェクショット) is activated when Drive loads a Shift Car into its Shift Landing Panel (シフトランディングパネル) (in Gold Drive's case, either loading them into his Shift Brace or not) behind the barrel after turning his Drive Driver's Advanced Ignition. Drive=
 * Shift Speed: Drive fires several flaming shots, then accelerates them by kicking an energy wheel that forms on the side into their path, slamming into their target at terminal velocity.
 * Fire Braver: Drive fires a beam of energy resembling the Ladder Expander, which grabs the enemy and pins them to the nearest wall before he pulls the trigger to detonate the energy construct, taking out the target along with it.
 * Rolling Gravity: Drive fires a ball of energy resembling the 10-ton Weight, which flies over directly above the enemy and pelts them with a series of bullets before the energy construct falls like a rock, detonating as it hits the target.

Arms Weapon
The Door-Ju is an Arms Weapon wielded by either an Armored Rider or a New Generation Rider when they transform into Drive Arms. It is absent when Kamen Rider Gaim uses Drive Arms in Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle, solely wielding the Handle-Ken. However, it is avaliable alongside the Handle-Ken in the Arms Change series.
