Description: Requires Kuroari and Sanshuou (Karasu is Optional): After extending the scoops on Sanshuou's legs, the user controls him to dig underground, tunneling under the opponent. Then he/she sends Kuroari in the tunnel, under the opponent. After the opponent and Kuroari are in position, Kuroari violently pops up from underground, his Chassis open, catching the opponent inside unexpectedly. After so, the final part of Kurohigi Kiki Ippatsu or Kurohigi Kiki Nihatsu can be used.
History: Used by Kankuro, but never named, Reido heard stories of him using this technique by reports of the site where Sasori and Kankuro had their battle. (Although Kankuro used a different method to move Kuroari underground) He recreated this technique by equipping Sanshuou with scoops to dig.
