Fighting Tongue Bind

After focusing senjutsu chakra to her tongue it grows to its maximum limit and has been reshaped with a face. The tongue will then seek out the scent of its target. When the target is found, she ensnares it to prevent escape and marks it with a corrosive chemical. Shima uses this to find Pain's camouflaged Giant Chameleon, allowing Fukasaku to use Fighting Tongue Slash on it.

Trivia

 * "Zessen" is written with the kanji for "tongue" and "battle". It can be translated as to "battle with tongues". In normal use, however, it means "war of words", or "verbal dispute". Just like Fukasaku and Shima are having all the time. The full kanji can be translated as "War of Words Binding".
