When the user implements this fūinjutsu on a summoner, it removes any direct control the summoner has over a summoned creature. Close contact appears to be required for the implementation of the seal. Minato Namikaze used this technique to wrest a Sharingan-controlled Kurama from Tobi's control. Though the Contract Seal removes the summoner's ability to control its summon, it does not give the user of the fūinjutsu the ability to control the summon in turn, nor does it remove a summoner's ability to continue to summon the creature.

Trivia

• In an anime cutscene of Tobi's storyline in Naruto Shippūden: Ultimate Ninja Storm Generations, Hashirama performs the technique on Madara during their battle, though in the manga, the reincarnated Madara attempted to summon Kurama during the Fourth Great Shinobi World War, demonstrating that the summoner does not lose the ability to summon a creature, and that it just breaks the nature of control over it at that moment.
