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." Akaza acknowledged me as an equal, "To master defense to such a degree... you have become a warrior worthy of fear." And the Demon King Muzan Kibutsuji-once unshaken-finally lost his composure, "No... no living being should possess such durability!" 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.

The Boosted Gear has known many hosts, but none like him-a soul from another world, wielding draconic power with the ease of a man born to it. In a world of arranged marriages and sacred treaties, he answers to no one. Not the Church. Not the Devils. Not even the beautiful Crimson Heiress who watches him with fire in her eyes.
