Contract Seal

A basic contract seal that prevents the target from using the Summoning Technique. It also causes Obito Uchiha to lose control of the Nine-Tailed Demon Fox when Minato used it on him in their battle.

Hashirama performs the technique on Madara during their battle in the anime, though in the manga, the revived Madara attempted to summon Kurama during the.

Though this removes the control a summoner has on a summoned creature, this does not mean that the user of the technique gains control over the summoned creature.
