Wood Release: Wood Coffin Burial Technique

Akuhei Iwao utilises this technique to create a tough, wooden coffin-like structure which spontaneously traps an opponent after it erupts from underground around the opponent, effectively trapping them. Several spikes are formed on the coffin, impaling the victim before the coffins are dragged back underground. Iwao sadistically describes this as a "cost free burial, on the house".
