While Touya rose to the rank of Commander, a shadow emerged on the New World—a pirate known as "Dread Sun Eater – Kael D. Vorn." In reality, it was Touya's high-tech clone, a vessel used to harvest the "Prime Variables" of this world. The clone moved like a ghost, extracting blood samples from Kuzan, Borsalino, Sakazuki, Whitebeard, Marco, Charlotte Katakuri, Donquixote Doflamingo, Bartholomew Kuma , Kaido and even securing an artificial Azure Dragon Fruit. Kanae and Shinobu was kept in dark
Back in the East Blue, the real Touya secured the Mera Mera no Mi in easy blue and systematically dismantled Crocodile's operation in Alabasta. He didn't turn the Warlord in; he stuffed the "Desert King" into his soul-bound space, replacing him with a biological dummy for the Marines to find. Later, alongside Kizaru, he raided Skypiea. While the Admiral played with Enel, Touya's nanites were busy draining the "God's" lightning-charged blood.
The stage was set. Touya requested a Zoan fruit as a reward, which Sengoku granted, but the "Architect" was already planning his exit. He needed to leave this world's narrative without leaving a trace that could be followed.
The "Fake Death" plan was initiated during a routine patrol. The clone, Kael D. Vorn, intercepted Touya's ship. The battle was a masterpiece of deception. Kael, augmented with "future-tech" limbs, tore through the crew. He "slaughtered" the clones of Kanae and Shinobu before Touya's eyes.
In that moment, seeing the lifeless faces of the women he had grown to cherish—even if they were duplicates—something snapped inside Touya. A wave of Conqueror's Haki erupted from him, so dense it cracked the hull of the ship. He suppressed it instantly, pouring every ounce of his Haki into a final, suicidal strike. Kael's arm impaled Touya's chest as the Admirals' ships appeared on the horizon. The clone escaped, and Touya, coughing up "blood," crawled toward the bodies of his sisters, dying in a tragic tableau of failed protection.
