Scroll of Seals

The Scroll of Seals is a scroll containing many kinjutsu, starting with the Multiple Shadow Clone Technique. Because of the dangerous techniques it contains, the scroll was sealed away by the First Hokage.

After failing his graduation exam, Naruto Uzumaki was tricked by Mizuki into stealing the scroll from the mansion of the Third Hokage, stating that if Naruto can learn one technique within it, he would be allowed to graduate (which did turn out true). This was apparently mostly dangerous because the scroll contains techniques that might have unleashed the Nine-Tails, sealed into Naruto. This means it might also contain the Dead Demon Consuming Seal or the Eight Trigrams Sealing Style.
