Chapter Summaries

After waking as a fish near Thriller Bark, Xia Qiu explored a nearby island and ate two large shrimp. His body then underwent a painful change, and after digesting the meal in half an hour, he became hungry again.

• Xia Qiu caught and ate two sea shrimp, then estimated his size and weight.
• Xia Qiu felt heat and swelling pain after eating, hid in the sand, and endured the changes for half an hour.
• Xia Qiu defecated and became hungry again, suspecting something abnormal was happening to his body.

Xia Qiu hunted large yellow croaker and observed his rapid growth and unusual abilities while trying to identify the waters where he had transmigrated. He spotted a ship bearing the One Piece Marine emblem, leaving him shocked and unsure where he was.

• Xia Qiu examined the traces of his growth and wondered why he grew so quickly after eating sea shrimp.
• Xia Qiu attacked a school of large yellow croaker, killed one, and ate its flesh.
• Xia Qiu endured a stronger warm current and noticed sand lance feeding on the large yellow croaker's remains.
• Xia Qiu surfaced, saw an island covered in Sea Mango, and guessed he might be in the South China Sea.
• Xia Qiu saw a three-masted ship bearing the Marine emblem and wondered how he had reached the world of One Piece.

Xia Qiu discovered that he had been transported to the world of One Piece after spotting a Marine warship and overhearing sailors discuss the Goa Kingdom and Celestial Dragons. Realizing how dangerous the world was for a fish, he gave up on grand ambitions and decided to live an ordinary life.

• Xia Qiu approached a sailing Marine warship and recognized its uniforms and Seastone-lined hull as evidence that it was real.
• He entered the harbor and overheard two sailors complain about the Marines’ fees and discuss the Celestial Dragons’ visit to the Goa Kingdom.
• Xia Qiu connected the Marines, Seastone, Goa Kingdom, and Celestial Dragons to One Piece and concluded that he had entered that world.
• He considered the danger and difficulty of becoming powerful enough to pursue his ambitions, then decided to live an honest life and sank to the bottom.

After half a month of feeding and evolving, Xia Qiu grew into a powerful fish and learned that he was in the East Blue during a pivotal year in One Piece history. He found shelter in a sunken boat, where an increasingly intense itch began spreading across his body.

• Xia Qiu ate a crab and a yellow croaker before heading back toward the harbor.
• Xia Qiu reflected on his growth, his exploration of the island, and what he had learned about Naruto Village and the year 1510.
• Xia Qiu swam to a sunken fishing boat and settled inside its cabin as a place to rest and hide.
• As Xia Qiu waited for his food to digest, heat flowed through his body and an itch grew unbearable.

Xia Qiu’s old scales fell away and were replaced by tougher, silver-white Ctenoid Scales, making his body stronger. After two days of voracious hunting, he felt confident in the waters near the island but knew he still needed to grow to survive larger predators farther out.

• Xia Qiu felt an intense itch and watched nearly half his Cycloid Scales fall off as he rubbed against the ship cabin and seabed.
• Sharp pain spread across Xia Qiu’s body as new silver-white Ctenoid Scales grew in, and he realized he was replacing his scales rather than suffering from an illness.
• Xia Qiu hunted sea shrimp, sand dartfish, crabs, and other fish to satisfy the hunger that accompanied his rapid growth.
• Over two days, Xia Qiu replaced all his Cycloid Scales, and his body became rounder, tougher, and stronger.
• Xia Qiu snapped a warped ship plank with his body and judged himself invincible near the island, but he remained wary of larger fish in deeper waters.

Xia Qiu expanded his hunting grounds to satisfy his growing appetite, but a school of sharp-toothed fish injured him when they swarmed him. After returning to the sunken ship, he discovered that eating gave him enough energy to heal his wounds quickly.

• Xia Qiu hunted down and ate a large bass in deeper water.
• A school of small fish surrounded Xia Qiu and bit his vulnerable barbels, fins, and belly.
• Xia Qiu shook off the attackers, crushed some against the sand, and escaped back to the sunken ship.
• Xia Qiu's wounds healed within an hour as his food digested, revealing that he could recover quickly when he had enough to eat.

• Xia Qiu ambushed and killed a tiger shark with a powerful tail strike and bite.
• A school of hundreds of purple fish swarmed the shark’s corpse and attacked Xia Qiu, whose scales resisted their bites.
• Xia Qiu swallowed several purple fish, then fled when the rest of the school arrived and hid in an underwater trench.
• Xia Qiu considered its new size and abilities, the danger of large schools, and its boredom with its repetitive life.
• Xia Qiu longed to meet others and explore the world, but fear of danger made it resolve to grow stronger and rest.

Eli, Lia, and Angelo learned that the Marines planned to deal with the enormous sea fish near Naruto Village, while Captain Kurume prepared a trap under orders from Lieutenant Colonel Berio. At dusk, Xia Qiu spotted the baited trap in the harbor and realized it was meant for him.

• Eli met Lia and Angelo beneath a tree, and the children discussed the dangerous sea fish near the shore.
• Captain Kurume collected the village's security fee and agreed to kill the sea fish for an additional payment.
• Lieutenant Colonel Berio kept the payment and ordered Kurume to lead the sailors in dealing with the fish before the Marines had to return to base.
• Kurume ordered the sailors to gather bait and equipment, and they prepared to capture the sea fish.
• Xia Qiu swam into the harbor, spotted a lamb surrounded by nets and attached to a chain, and recognized it as bait for a trap aimed at him.

Xia Qiu escaped the warship’s net and weapons, but Lieutenant Colonel Berio pursued him underwater and wounded him with harpoons. Unable to flee with his injured tail, Xia Qiu turned to fight Berio.

• Berio repeatedly wounded Xia Qiu with his harpoon, but Xia Qiu realized Berio would eventually need to surface for air.
• Xia Qiu used his pectoral fin and tail to drive Berio away, then blocked his route to the surface and forced him to charge.

• Xia Qiu reflected on how dangerous Berio had been and swam away to recover from his wounds.
• A powerful, scorching current coursed through Xia Qiu as his injuries healed, and he swallowed fish drawn by the scent of his blood.

• The pirate captain accepted the deal, and his men began rowing the supplies back to the ship.
• Xia Qiu charged toward the two returning boats.

• Naruto Village residents discussed the danger Xia Qiu might pose to fishing and merchant ships, and the village chief planned to ask the arriving Marines to kill it.

Kurume sailed to Naruto Village after receiving a report of a pirate attack, but found that the Porcupine Pirates had already been devastated by the Black Fish. After reporting the creature as a growing sea-beast threat to the Marines, he left the matter to Colonel Lido while Xia Qiu wondered where to find powerful humans to strengthen himself.

• Xia Qiu hid in an ocean trench and realized that he needed to find powerful humans to gain more Reinforcement Energy and grow stronger.

Xia Qiu hunted tuna and grew spikes, then followed a powerful scent that made him ravenously hungry. The scent came from a Marine trap set by Colonel Lido and Kurume, who planned to kill Xia Qiu and use the deed to promote Kurume.

• Xia Qiu devoured tuna schools and grew hard spikes along his back and belly, discovering he could gain traits from certain marine fish.
• Xia Qiu continued hunting and reached eighteen meters long and nearly fifty tons, while remaining cautious as he explored deeper waters.

• On a Marine warship, Kurume and Colonel Lido used Capture Agent to lure Xia Qiu, hoping to kill him for military credit.
• Lido promised Kurume the credit and promotion, valuing his loyalty and administrative ability despite his limited strength.

Xia Qiu discovered that the Marines were using a scent to lure large fish and realized they were tracking him. He turned to confront the warship, and Colonel Lido jumped into the sea to hunt him.

• Xia Qiu realized Lido had been a Marine Colonel and resolved to grow stronger before swimming away from the warship’s fire.
• Xia Qiu encountered a sea fish at least thirty meters long that charged toward him.

Xia Qiu fought a gigantic Coelacanth while injuries and a body-strengthening heat flow weakened him. After badly wounding it, he pursued what he thought was its retreat and realized too late that it had turned to attack him again.

• Xia Qiu spotted a thirty-meter Coelacanth and fled, but the enormous fish kept pace as the heat flow in his body intensified his pain and slowed him.
• When the Coelacanth lunged from behind, Xia Qiu dodged, turned, and bit into its side, then slipped beneath it to tear a larger wound from its belly.

• Xia Qiu shattered the coelacanth's upper jaw, tore off both pectoral fins, and ripped open its belly until it fell onto the seabed.
• Xia Qiu ate the coelacanth, then endured two hours of pain as Reinforcement Energy and Evolution Energy transformed him.
