Katanagatari — S1E8 · Sai, the Minute

Having returned to Owari, Togame's home, Togame and Shichika meet with Princess Hitei who tells them about the location of Shikizaki Kiki's workshop and the possible sword hidden there. Following the lead, although distrusting of it, the two go to the location, Lake Fuyou accompanied by Emonzaemon. Upon their arrival, Emonzaemon departs and leaves Togame and Shichika to deal with Bito Kanzashi. While away, Emonzaemon tracks down Umigame Maniwa and reveals that he is the sole remaining heir of the Aioi Corps, a village of ninjas that were wiped out by the Maniwa Corps 170 years ago. Having told him this, he engages Umigame in battle and defeats him completely and effortlessly using Aioi Kenpo.
