This technique shapes a large amount of water into a giant, powerful dragon, which hits the opponent with formidable might, dealing physical damage. The ideal place to use it is near a body of water, but if the user's skill allows it, it is possible to use it even in a place where there is none. The amount of water used will be in proportion with the user's skill.
During this technique's first appearance, forty-four hand seals were used to perform it; the highest amount of hand seals necessary to use a technique shown in the series so far. However, later appearances of the technique have implied that the exact number of seals required isn't fixed.
When conducting A's lightning-natured chakra through this technique, Mei Terumī referred to it as "Lightning Water Dragon Bullet" (雷水龍弾, Raisuiryūdan).
