Eighty Gods Vacuum Attack

Kotoamatsukami!

The "strongest Illusion Technique" housed within Shisui's Mangekyo Sharingan could directly invade an opponent's mind without them noticing and permanently, completely alter their will.

According to rumors, Kotoamatsukami was known as the strongest Illusion Technique for controlling wills. Anyone the caster set eyes on could be turned into their puppet!

Its drawback was its excessively long cooldown. Without Hashirama's chakra, the cooldown could last more than a decade. Duke did not have Hashirama Cells, but he possessed the Yang Release of Six Paths Power, so Kotoamatsukami's cooldown was not quite so outrageous.

According to further rumors, the strongest Illusion Technique could crush all living beings. Forget Six Paths Madara—even if the Sage of Six Paths' mother showed up, she would become an RBQ the moment you wanted her to. Tie her up in the basement, make as many tally marks as you liked, and having Six Paths-level sons would be as easy as playing around.

Whether any of that was true was hard to say. In the original work, only Itachi had been hit by this Illusion Technique. Everyone else had merely heard of it.

Of course, the rumors might have been true!

It was not impossible that the Sage of Six Paths' grandfather had come to Earth searching for his runaway daughter, only to have Shisui alter his will and return to his alien home to find his daughter a stepmother.

Without anyone knowing, Shisui had saved countless lives in the Shinobi World.

What followed was that Kotoamatsukami entered its cooldown period, Danzo ambushed Shisui, and Shisui gave his eye to Itachi. More than ten years later, the cooldown ended. Kotoamatsukami saved Itachi, and Itachi saved the Shinobi World...

What an incredible eye. Without anyone realizing it, it had saved the Shinobi World twice!
