Evil Sealing Method

This jutsu is used to suppress jutsu-induced marks on a person. Marks of weaker power can be completely suppressed by this jutsu alone, but for marks of higher power like Sasuke Uchiha's Cursed Seal of Heaven, causes the seal's power to become dependent on the recipient's own willpower to some extent. It is also capable of holding back certain Kekkei Genkai, such as that of the Kurama clan as seen when Kurenai tried to do this.

This seal requires a number of hand seals and a large amount of chakra to be performed. Preparation for this jutsu requires two concentric circles with kunai placed in intervals along the circumference, in addition to a number of characters written in blood that radiate out from the center of the curse seal.

According to Kakashi, this jutsu is quick, but painful. The seal can be removed at any time by the caster or whoever the seal is on, as demonstrated during Sasuke's battle with Naruto in the Valley of the End. Since this seal does rely on the will of the individual on to whom its placed the affected may be able to just will it away without an unsealing jutsu.

When Orochimaru was extracted from Sasuke through Itachi's Sword of Totsuka, not only was the Cursed Seal of Heaven removed, but also the Evil Sealing Method around it.
