Ikaiyo's signature technique, it allows the rapid movement through water molecules. the amount of water doesn't matter, thus resulting in the technique being able to used virtually everywhere. Ikaiyo has mastered the technique to the point that many people believe that he used Space/Time Ninjutsu to teleport himself to another place, while he actually moves through the water molecules in the air. This allows him to dodge even point-blank attacks, and makes it incredibly hard to hit him in battle. It is unknown if a hand seal is required every time the technique is used, but Ikaiyo claims not.
