Twin Snakes Mutual Death Technique

This forbidden jutsu 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 jutsu against Orochimaru, he replaced himself with a clone to avoid harm, leaving Anko unable to finish the jutsu.

Trivia
* In Naruto: Ultimate Ninja 3, when Anko performs this jutsu, 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.
 * Also this jutsu activates Anko's Curse Mark Stage 1, but only if it is used against Orochimaru.
