The black gravitational core hovered in midair like an ominous star of calamity.
In Uesugi Sasuke's left eye, the pattern of the Six-Tomoe Rinnegan spun rapidly, pouring out ocular power with unprecedented intensity.
Damn, this is consuming more than I expected.
Chibaku Tensei essentially created an ultrahigh-density gravitational singularity, then wrapped it in chakra to keep it from running out of control. It was exceptionally effective against pure energy beings like the Tailed Beasts, but against someone like Kokushibo, who had honed his will and swordsmanship to their utmost limits...
Sasuke could clearly "see" countless building remnants, broken corridor pillars, and shattered tatami mats being wrenched and torn away by that invisible force within the Infinity Castle's distorted space, swarming madly toward the black core in the sky like moths drawn to a call.
Rumble-
An enormous sphere composed of countless ruins was rapidly taking shape. Its shadow shrouded the battlefield, bringing an oppressive sensation like the coming of the apocalypse.
Yet just as the sphere was about to close, a dazzling ray of moonlight burst through a gap from within.
"Moon Breathing, Sixteenth Form: Moonbow: Lone Lingering Moon!"
A trace of grim resolve colored Kokushibo's voice. The immense gravitational pull held him fast, and the bones in his body groaned under the unbearable strain. Yet at that moment, the Demon Blade in his hand unleashed the most brilliant-and most obsessive-slash of his entire life as a samurai.
It was not merely sword energy.
Through Sasuke's Rinnegan, it was a "blade of rules" formed from pure sword intent, endless demonic energy, and Kokushibo's own unyielding obsession. The instant it struck, it did not rush toward Chibaku Tensei's gravitational core. Instead, it slashed directly at the "principle" sustaining this "heavenly star."
"Trying to seal me? My sword can sever even fate!"
