To activate the finisher, a Ranger needs to place a Fury Disk into the middle of the weapon, making the weapon announce "Now, the Karakuri!" (ザ・カラクリ！ Sa Karakuri!?), allowing the Karakuri Hengen to announce, depending on which mode it was in, "Sword Transformer Slash!" (刀変幻斬 Katana Hengen Zan!?), making the blade glow the same color as the Ninninger wielding it, "Bow Transformer Shot!" (弓変幻射 Yumi Hengen Sha!?), making it fire an arrow glowing in the same color as the Ninninger that fired it, or "Claw Transformer Rend!" (爪変幻裂 Tsume Hengen Retsu!?), making the claws glow the same color as the Ninninger wielding it.
