One Piece: The Strongest Experimental Subject at the Beginning
A traveler without a system—Subject No. 88.
On Punk Hazard, he was known as the strongest experimental subject: the perfect adaptor, the sole survivor.
Souta Kiryuu carries within him countless rare bloodlines, from the Oni, the Lunarians, and the Ancient Giants, to many others long thought extinct. Layer upon layer of genetic modification has reshaped his body, endowing him with terrifying powers—searing lasers, deadly toxins, and the ability to vanish into transparency.
During the catastrophic poison gas explosion, Souta seized his one chance at freedom. Consuming the artificial Azure Dragon Fruit, he finally escaped the nightmarish prison of Punk Hazard.
Now reborn as a raging dragon, his fury burns across the seas. Souta Kiryuu will not rest until he overturns the world order itself—and slays Satan, one of the Five Elders!
