When I awoke, I found myself in the perilous world of Demon Slayer. Bound to a mysterious system-the Ultimate Defense System! Mitsuri Kanroji murmured in awe, "His strength surpasses even mine..." Kagaya Ubuyashiki nodded in admiration, "Truly, the Demon Slayer Corps' strongest shield." Even the fearsome Kokushibo conceded, "You embody the strongest defense our generations have ever seen."

In a world where offense reigns supreme, I chose the path of resilience. I do not wield a blade to kill. I stand to protect. No demon shall pass me. No comrade shall fall behind me. I am not the hero this world expected- I am its unbreakable shield.

Since he couldn't become a Jujutsu sorcerer, he would forge a new path, a Shinigami with Heavenly Restriction! Thus, Gojo Satoshi, born without cursed energy yet possessing the legendary Six Eyes, became the true nemesis of Jujutsu sorcerers.
