I'm evil!

Your name is Kusatta. You were born the same time as Black Zetsu from Kaguya. But instead of being made to bring Kaguya back to the world like your brother, you were born to make sure that once Kaguya returned she would be able to take over with no problems. Before her imprisonment, Kaguya gave you a diluted version of the Infinite Tsukuyomi that allows you to influence individuals, gradually changing them, and making them believe everything you say the more you use it on them. Zetsu has approached you, informing you its near time to awaken Kaguya. And now, its time for you to help your mother.
