- Name: Water Style: Killer Whale Jutsu (水遁・鯱の術 Suiton: Shachihoko no Jutsu)
- Type: Ninjutsu
- Users: Ankō Shachihoko
- Hand Seals: Ox, Monkey, Rat, Boar, Rooster
Befitting of Ankō's family name, this technique creates a giant killer whale made of water that Ankō can either ride upon or launch at his enemies as a projectile. A technique very special to the Shachihoko clan, the ability to use it represents a coming of age in the family, similar to the Uchiha clan's use of Fire Style: Fireball Jutsu.
