With a single glance of the Sharingan, this technique forces a nightmarish genjutsu on the victim, overpowering them and bringing them to their knees. Even the usually emotionless Sai was deeply affected by this genjutsu.
The potent and fearsome nature of tailed beast chakra allows Ryuuki to perform this technique with a lot more power than most Uchiha. He was once able to bring an entire army of shinobi to their knees all at once with ease when they all looked at his eyes. He is also able to add his Killing or Evil Intent and refers to this form of the technique Sharingan: Killing Intent and Sharingan: Evil Intent respectively.
