Twin Snakes Mutual Death Technique

is a forbidden technique, which is a murder-suicide attack, killing both the user and the target. The user makes a one-handed seal with both their hand and the intended victim's. Two snakes are then summoned from the user's sleeve, biting both their wrists and killing them with deadly venom. When Anko Mitarashi used this technique against Orochimaru, he replaced himself with a clone to avoid harm, leaving Anko unable to finish the technique.

Trivia

 * In Naruto: Ultimate Ninja 3, when Anko performs this technique, two summoned snakes wrap themselves around her and her victim and lock themselves in that position by biting each others' necks, the snakes then detonate. For game play reasons, however, Anko is left unharmed.
 * This technique also activates Anko's Cursed Seal of Heaven, but only if it's used against Orochimaru.
