The is the transformation device and personal weapon of Kamen Rider Durendal.https://www.nihonhero.com/post/blades-tategami-hyoujuu-senki-first-scan-kamen-rider-durandal-scans?fbclid=IwAR34gtqrCMqSNUUr-7guHiw43ATga1WsDNEnLXlr0c_iIenht-VCNWJ-3EA
==Design==
The Jikokuken Kaiji is composed of the following parts:
*: The hilt. It is designed to maximize the Kaiji's attack power in both Sword and Spear modes.
*: The trigger. When operated by a swordsman, the Jikokuken Kaiji forms a mental link with the wielder and distorts time. It also assists in initializing Rider Finishers.
*: The source of Kaiji's time powers. It has the role of granting the Seiken the power to reverse time and protecting the wielder at the present time. The coat of arms representing Kamen Rider Durendal is engraved in the center.
*: The base of the Jikokuken where the Wonder Ride Book is placed in. In addition to drawing power from the Wonder Ride Book and transmitting it to the Seiken, it also brings various abilities to the "Sword Robe".
*: The input device for the Seiken's blade portion. By removing and altering the blade, the Wonder Ride Book will activate and the swordsman will transform. After transformation, the user can change the mode by removing and altering the blade's position.
*: The blade end. Being forged by holy flames over the frost of stars, the blade has the ability to increase its sharpness each time it utilizes its time power.
*: The trident end. It has excellent piercing power and can be used as a harpoon by expanding and contracting.
==Modes==
The Jikokuken Kaiji has two modes: the basic and the trident-based . The two modes are alternatively named and https://twitter.com/RedMemoraiza/status/1377153401033646083/https://www.tv-asahi.co.jp/saber/rider/item/jikokuken_kaiji.html respectively.

==Functionality==
===Transformation===
To transform, the user plugs the Ocean History Wonder Ride Book into the slot before pulling the Tri Edge out of the Kaiji Splitter before inserting the Kaiji Edge instead changing the weapon to its spear mode. The user then appears in a library surrounded by waterfalls, delivering a diagonal slash as a projection of a school of fish surrounds the user and forming the armor. The diagonal slash then forms the visor, finishing the transformation.
===Kaiji Erasure===
By pulling the trigger while the hilt is detached, Durendal can activate the unique ability of the Jikokuken Kaiji called the , which allows him to erase a given frame of time lasting up to few seconds. During this period, other people will perform the actions that they would have otherwise, but are unable to experience anything in the erased time frame and will retain no memories of it. Durendal, however, is aware of his surrounding and is able to see the actions others would have taken within the erased time frame. Durendal is also able to move within the erased time, allowing him to avoid enemies' attacks or perform ambushes. 
The ability ends when Durendal reattaches the hilt and presses the trigger again. After the state ends, other people will suddenly find themselves in the situation they were supposed to be afterwards, with both themselves and Durendal appearing to have teleported.

# Pressing the trigger three times in a row.
