Ultra Super Butt Festival Duet (超々尻祭連弾, Chōchō Shirisai Rendan) is a technique used in Keijo.


Moving at high speeds, the user places their butt on multiple places. Producing a vast amount of butts, their butt later takes the form of an Oni, and is accompanied by a dragon. The attack can't be blocked easily as the user is fully protected by a series of butts. By using this technique, Sayaka is able to defeat Naki Kujaku.
