Shinkenmaru

Secret Playback Katana Shinkenmaru (秘伝再生刀シンケンマル Hiden Saiseitō Shinkenmaru?): The Shinkenmaru is the Shinkengers' primary sidearm. It is first activated by taking any of the Secret Disks (秘伝ディスク Hiden Disuku?) from a compartment on the Shinkengers' belts and attaching it to the hilt to become the guard. By spinning that Secret Disk, the Shinkenmaru acts as a praxinoscope and it powers up depending on the disk itself. By spinning the Common Secret Disks fast enough, the Shinkenmaru transforms into the Shinkengers' signature weapon. Using a personal Secret Disk allows a Shinkenger to execute a Spiral Sword (螺旋之太刀 Rasen no Tachi?) attack depending on the element that the disk represents. The five Spiral Sword elemental attacks can be used in the Quintuple Sword (五重之太刀 Gojū no Tachi?) attack. The four Spiral Sword elemental attacks can be used in the Four Continual Slash (四連斬り Yonren Giri?) and the Quadruple Sword (四重之太刀 Yonjū no Tachi?) attack.
