Forbidden Individual Curse Tag

A cursed seal that is placed directly on the target's heart. The cursed seal is designed to restrict or force certain actions on the target in key situations such as preventing them from taking their own lives and removing the cursed seal themselves. Directly striking the heart appears able to remove the seal, albeit risking one's life in the process. According to Obito Uchiha, the cursed seal also interfered with him becoming the Ten-Tails' jinchūriki.

Trivia

 * Both Rin Nohara and Obito Uchiha, who were branded with this cursed seal, had it removed by Kakashi Hatake's Chidori and Lightning Cutter, respectively.
