Tameshi Ittō-ryū Hiken: Futa wa no Tsuki (試一刀流 秘剣 二輪月, Literal meaning: One Sword School Test Cutting Secret Sword: Two-Wheeled Moon) is the "tenran" (展覧試, Literal meaning: exhibition) form of the Tameshi Ittō-ryū where two Yamada Asaemons synchronize their blades to cut down a target in half. In a Tao illusion, Sagiri and Shion used this technique in combat to destroy Rien's tanden.
