He was once Ryan Hart, a rising star in the Naval Science Corps, immersed in the cold world of formulas and data. However, a deliberately hidden fragment of an ancient weapon design drew him a fatal cleansing order from CP0, the top minion of the world government - to "recover all unstable elements", including his brain. In a desperate situation, Renn detonated his homemade electromagnetic pulse device, hijacked the ship and fled in the blue light of destruction. He was seriously injured and on the verge of death and drifted to the ruins of Future Island.
After being rescued by the mad scientist Grigo and given a mechanical prosthetic limb to regain his life, what awaited Renn was the cold "death declaration" from the Navy. The world declared that the traitor had been executed by Shen Hai. But when a storm raging night, a black ship "Impulse" with a destructive blue arc wrapped around it and a lightning emblem branded on its bow tore through the sea surface, the lie was ruthlessly shattered!
Combining the forbidden blueprint technology with his own awakened electromagnetic power, Wren transformed into Captain "Pulse" and roared revenge against the hypocritical world. His iron hand controls the electromagnetic force field that can deflect cannonballs, the terrifying impact that tears apart steel ships, and the world-destroying main cannon that makes the entire sea tremble. The cold mechanical eyes overlook all living beings, and every pulse of the arc is a ruthless judgment on the betrayers of the past.
However, during the dangerous voyage of the Grand Line, a fatal encounter occurred unexpectedly. Anne, a red-haired dancer who is as passionate as fire and dances as wildly as a firestorm, has a ruthlessness and secret that is no less beautiful than her molten gold eyes. Like an unpredictable wildfire, she bursts into Captain Pulse's cold world, bringing dangerous intelligence and deadly temptations.
