Inhuman Makyo Shinjuku Showdown, Part 14

Hajime Kashimo, the God of Lightning, hurls himself forward as the next to take on Sukuna. His aim is twofold: to bring down the King of Curses and to grasp what it genuinely means to stand as the strongest.

From two hundred three meters up, Kashimo descends to challenge Sukuna, just as a huge ice block sinks toward them with Uraume, the Frozen Star, perched on top. Hakari, who had foreseen the interference, strikes from overhead, declares he vowed to secure Kashimo a clean one-on-one, and locks Uraume within his domain. The plummeting ice reaches Sukuna, who cracks it open and snatches the prize inside: a flawless duplicate of Kamutoke, the cursed tool. That replica was crafted by Yorozu as a parting present for Sukuna, sealed through a binding vow as her own life drew to an end. Sukuna immediately rains lightning down, yet Kashimo's potent electrical resistance renders it harmless.

Before the duel, Kashimo presses Sukuna on whether the title of strongest was earned or his from birth; Sukuna replies only that his birth was a cursed and unwanted one. When Kashimo, who could never bond with anyone weaker, asks whether strength means endless solitude, Sukuna brands him greedy like Gojo and offers to teach him. The clash begins, Sukuna deflecting with Kamutoke until Kashimo triggers Mythical Beast Amber, whose burst of speed lands clean strikes and a shout fierce enough to crack a sonic boom. The technique rebuilds his body to turn any electrical phenomenon into a weapon, sharpening reflexes, tuning sound, and vaporizing irradiated matter, but pushes him past human limits so that his flesh will collapse once it ends. Kashimo batters Sukuna with a signature lightning combo, yet Sukuna endures by mending himself without reverse cursed technique, a single-use method he had saved, fully incarnating back into his true original shape.
