Out of the corner of his eye, Sasuke caught sight of the Second Hokage Tobirama Senju's icy expression.
At the same time, with a thought, Sasuke manifested his skeletal Susanoo. A skeletal arm swept out, knocking away every Flying Thunder God Kunai.
"The evil Uchiha Clan brat seems to know the Flying Thunder God Technique quite well!" Tobirama Senju narrowed his eyes and appeared beside Hiruzen Sarutobi with a thought.
"Monkey, we're leaving!" Tobirama Senju said quietly, then prepared to disappear with Hiruzen Sarutobi.
Seeing this, Sasuke's lips curled into a faint smile. He had anticipated exactly this.
"Futsunomitama: Black Lightning!"
Crackle!
Countless bolts of black lightning erupted from Sasuke, spreading in every direction and instantly engulfing Tobirama Senju and Hiruzen Sarutobi.
"This is... pain?! How can a reincarnated body feel pain... This attack is hitting the soul!" The moment the attack struck him, Tobirama Senju realized something was wrong.
He was exceptionally accomplished in matters of the soul himself. Otherwise, he could never have developed a forbidden technique like the Impure World Reincarnation Jutsu.
Watching Tobirama Senju and Hiruzen Sarutobi freeze in place, unable to escape with Flying Thunder God, Sasuke gave an icy smile.
He held no affection whatsoever for either of them.
With a thought, the Futsunomitama Sword appeared in his hand, wreathed in black lightning.
The longsword, wrapped in black lightning and radiating the power to destroy all things, swept down toward Tobirama Senju and Hiruzen Sarutobi.
Just as the black Futsunomitama Sword was about to strike them, a golden streak pierced the thunder domain. Though it had moved later, it arrived first, colliding with the sword of destruction.
Black lightning and golden chakra tangled together, erupting into a storm of destruction.
Once Sasuke saw who had arrived, disbelief filled his face.
It was Naruto Uzumaki!
