Leech Break

Leech Break is a technique that Utakata uses in his transformed state. His body begins to secrete an extremely alkaline fluid that burns everything on contact. The substance is so powerful that Killer B, in his full Eight-Tails form, noted that it was capable of burning through his skin. When this technique was used in Version 2, Utakata's chakra cloak turned blue (in the anime). This offensive technique is designed for close combat and allows inflicting serious chemical burns.
