Users: Natsumi clan
Description: The Nijigan is a semi-well known kekkei genkai limited to the Natsumi clan. It grants the ability to release any genjutsu by one person. It can also control where a genjutsu is going. Like if someone uses the tsukyomi on someone else, the Nijigan user can make it so that it doesn't damage the victim. It can also master any genjutsu. This dojutsu makes you the master of Genjutsu.
