Luo Han and Princess Akatsuki reached Fish-Man Island, where fish-men mistook her for a captive and blocked their way. After Princess Akatsuki scolded Neptune and the crowd into letting them pass, Luo Han followed her toward the battle with John.

• Luo Han asked Princess Akatsuki to lead fish-men to his island in the New World, and she agreed to go but could not decide for the others.
• Fish-men outside Fish-Man Island saw the collars around Princess Akatsuki and Otohime and charged at Luo Han, believing the humans had captured them.

Meanwhile, Elles healed the Ryugu King, and Luo Han gathered the human traffickers and pirates who were attacking fish-men at the plaza, where Neptune and the returning fish-men headed to join them.

At Holy Land Mary Geoise, the Gorosei decided to lure Luo Han back to the Sabaody Archipelago and use a special Devil Fruit to kill him.

• Luo Han gathered the pirates and human traffickers above Fish-Man Plaza, announced that Captain John would die, and launched a Golden Spear at him.
• Captain John blocked the spear with his swords, but its crimson patterns ignited and triggered a massive explosion that killed nearly everyone caught in the flames.

• At Holy Land Mary Geoise, the Gorosei discussed Luo Han's actions, including beheading a Celestial Dragon, and resolved to eliminate him before his Haki grew stronger.
• The Gorosei planned to give a special Devil Fruit to the CP0 captain and prepare an ambush for Luo Han at the Sabaody Archipelago.

At a banquet in Ryugu Palace, the Ryugu King tried to keep Princess Chiyue from leaving with Luo Han, but Otohime’s awakened power forced the family to accept Chiyue’s choice. Luo Han discovered that Otohime’s ability could implant a will to protect Fish-Man Island, and he checked whether it had affected Cole and the others.

• The Ryugu King thanked Luo Han for saving Fish-Man Island and Princess Chiyue, then asked him to make another request instead of taking Chiyue away.
• Princess Chiyue insisted on honoring her agreement with Luo Han, while the Ryugu King and Neptune offered to take her place.
• Otohime’s power swept through the hall, changing Neptune’s and the Ryugu King’s minds so they accepted Chiyue’s decision.
• Luo Han knocked out nearly everyone on Fish-Man Island with his will and accused Otohime of tampering with his companions’ wills.
• Luo Han let Otohime’s power enter his mental world, discovered it could plant a lasting will to protect the Fish-Man Race, and forced the power out.
• Luo Han warned Otohime that Cole might have been affected, then examined Cole, Sister Shaku, and Sola.

Luo Han examined the effects of Otohime’s rare Observation Haki and discovered the secret behind Princess Akatsuki’s family’s behavior. After forgiving Otohime and deciding Akatsuki would join his companions, he led the group toward the Sea Forest, still uncertain what had happened between the royal family.

• Luo Han found that Cole and Sister Shaku had resisted Otohime’s influence, while Aixi had been left pitying the Ryugu King’s family and Sola’s willpower was exceptionally strong.
• Elles urged Luo Han to kill Otohime and the others, but Otohime offered her life to protect the Fish-Man Race and the Ryugu King tried to take responsibility himself.
• Princess Akatsuki suddenly struck Otohime unconscious, prompting the Ryugu King to tell Akatsuki to leave and never return; Neptune carried Otohime away for treatment.
• Luo Han forgave Otohime and explained to the others that her Observation Haki transferred others’ pain, planting seeds of will in those who failed to resist it.
• Luo Han told Akatsuki to lead the group to the Sea Forest and warned his companions not to blame her, then ordered Aixi to return to the Ark and strengthen herself.

Luo Han explained Aixi’s condition to Sister Shaku and persuaded her not to attack Otohime, revealing that he wanted Poseidon’s power to prepare for a future war against the World Government. After Sister Shaku left, Luo Han examined the red Poneglyphs to study their durability and strengthen his Psychic Armament.

• Sister Shaku demanded to return and seek justice for Aixi, but Luo Han restrained her and Sola until Aixi woke and asked what had happened to her.
• Luo Han took Sister Shaku into the Sea Forest and explained that Aixi would feel compelled to defend the Ryugu King’s family, but that his ability might eventually remove the effect.
• Luo Han told Sister Shaku that Otohime must live because her future daughter would become Poseidon, whom he hoped to enlist against the World Government.
• Sister Shaku accepted Luo Han’s plan and left him in the forest to handle Aixi’s situation himself.
• Luo Han studied the red Poneglyphs with his Divine Sense, intending to incorporate their indestructible quality into his Psychic Armament.

Elles awakened Yang Tree Eve and revealed that the Mermaid Princess had secretly turned Sea Kings against the Divine Tree Clan, breaking their agreement. She took a seed from Eve and ended their connection, while Chiyue suspected Elles was the friend from Fish-Man Island’s legend.

• Elles's mental waves awakened Yang Tree Eve, and their contact caused a tremor that shook the seafloor and made Fish-Man Island's sunlight flicker.
• Chiyue recalled a legend that Yang Tree Eve's friend's arrival would bring a tremor and darkness, while a figure at Holy Land Mary Geoise sensed that Eve had moved.
• Elles told Eve that the Fish-Man Race had betrayed the Divine Tree Clan and described how Sea Kings had attacked the clan whenever its Scale Fruits ripened.
• Elles identified the Mermaid Princess's mind-influencing command as the reason Sea Kings had attacked the Divine Trees, but Eve doubted her accusation and demanded proof.
• Elles ended her agreement with Eve, took a sunlit seed from the sea, and severed their connection.

Luo Han eavesdropped on Elles and Yang Tree Eve, uncovering the Divine Trees’ near-extinction and the Mermaid Princess’s role in controlling the Sea Kings, then concluded she had become Poseidon through Mind Power. While studying the Red Road Poneglyph, he discovered how its Seastone structure created a perfectly unified, Armament Haki-like force field and began trying to reproduce it, but realized the technique would take time.

• Luo Han overheard Elles and Yang Tree Eve reveal that Sea Kings had nearly wiped out the Divine Trees under the Mermaid Princess’s influence, and he suspected the Mermaid Princess had used Mind Power to become Poseidon.
• Luo Han learned that Yang Tree Eve was intelligent and had an agreement with the Mermaid Princess, then reflected that Elles could live more freely without the agreement’s constraints.
• Luo Han examined the Red Road Poneglyph and discovered that Wano’s craftsmen had fused Seastone and other materials into a structure that made it exceptionally durable and difficult to damage.
• Luo Han struck the Poneglyph with Armament Haki and realized its structure produced a perfectly unified force field resembling a denser form of Haki.
• Luo Han tried to arrange his own Armament Haki into the same force field but found the process too difficult to master quickly, so he flew back to tell Elles and the others they would stay there for a while.

Luo Han trained Elles to bring out Armament Haki, and her immense willpower let her awaken it with extraordinary strength in a single exchange. After recovering from her punch, Luo Han reflected on how willpower could refine Haki and break through defenses, while Aixi asked why Elles was already so physically strong.

• Luo Han decided to stay on Fish-Man Island and train Elles while the others rested near the Sea Forest.
• Elles repeatedly struck Luo Han until she coated her fist in Armament Haki and sent him crashing through several trees.
• Sister Shaku and the others realized Elles had brought out Armament Haki, which was already nearly as powerful as Sister Shaku's.
• Luo Han recognized that Elles's powerful willpower had refined her Haki and allowed it to shatter his defense.
• Aixi asked Luo Han to let her spar with him, but he said her physical strength was insufficient to awaken Armament Haki.
• Aixi questioned why Elles had reached the required strength despite only recently taking human form.

Luo Han focused on studying the Poneglyph while Elles agreed to spar with Cole and help him strengthen his Armament Haki. Chiyue remained determined to uncover what was wrong with her father, and Luo Han planned to continue his research before returning to the New World to find Lanternfish.

• Aixi returned with Luo Han, then shyly went to Sister Shaku as Elles teased him about sparring again.
• Luo Han asked Elles to train with Cole, and she agreed after Cole said their sparring would help prepare for the coming battle against the World Government.
• Chiyue asked Luo Han about her father and the others; he said he had a convincing guess but lacked evidence, and she vowed to find the truth herself.
• Luo Han went into the forest to study the Poneglyph while Elles struck Cole in a sparring session that made his Armament Haki more solid.
• At dinner, Sister Shaku asked about Luo Han’s new ability research, and he said it was going well but would take a few more days.

Luo Han repeatedly invited Aixi to spar in the woods, but she fled whenever he tried to confess his feelings. On the fifth night, Aixi came to him on her own, accepted his love, and became his woman.

• After dinner, Luo Han invited Aixi to spar in the woods, then confessed his feelings and asked her to be his woman, but Aixi blushed and ran away.
• Elles revealed that she had overheard Luo Han’s confession, and she teased him when Aixi ran from him again over the next few nights.
• On the fifth night, Luo Han went alone to their forest clearing, and Aixi followed him there after Sister Shaku encouraged her to follow her heart.
• Luo Han asked Aixi if she liked him, promised to always treat her well, and Aixi agreed to be with him.
• Luo Han and Aixi became lovers while Elles overheard them, and Luo Han ended the night declaring that Aixi was his woman.

Luo Han tried to understand the Poneglyph's Perfect Force Field and realized that willpower controlled the density and strength of Armament Haki. He left the sparring session with Elles having learned how willpower shaped Haki, but still needing to apply that insight to perfect his own.

• Luo Han found that his Armament Haki could not match the Perfect Force Field and that his Divine Sense could not penetrate it.
• At dinner, Luo Han realized Elles's willpower had shattered the will guiding his Haki when she first awakened hers, and he asked to join her sparring session with Cole.
• Luo Han secretly invited Aixi to spar in the forest, while Elles tried to eavesdrop and spent the night disturbed by what she heard.
• The next morning, Elles attacked Luo Han, but her restrained blows failed to break his strengthened Armament Haki.
• Elles infused her punch with all her willpower and clashed fists with Luo Han, cracking his Haki and helping him understand how willpower controlled its density.

Luo Han spent days trying to reproduce the Poneglyph’s Perfect Force Field as Armament Haki, but could not sense its inner structure. After using the special fluctuation of his Mind Power to enter Aixi’s mental world, he realized he could use it to inspect the field, formed Perfect Armament Haki, and planned to leave Fish-Man Island the next morning.

• Luo Han ended his spar with Elles and went to study the Perfect Force Field inside the Poneglyph, while Cole took his place as Elles’s sparring partner.
• Luo Han experimented with weaving his willpower into different Armament Haki structures, strengthening his Haki but failing to recreate the field’s unified, indestructible quality.
• After nearly twenty days of failed attempts, Luo Han prepared to leave Fish-Man Island and agreed to let Aixi stay with Sister Shaku while he sought a way to remove the seed of will from her mental world.
• Luo Han entered Aixi’s mental world and found that the seed of will had grown slightly, so he resolved to prioritize developing his Mind Power and curing her.
• Luo Han used Mind Power’s special fluctuation to enter the Poneglyph’s Perfect Force Field and discovered its structure of interconnected equilateral triangles.
• Luo Han arranged his willpower in the same triangular structure, created Perfect Armament Haki, and found that it could reflect attacks and resist abilities that could not break through its defense.

Luo Han returned to the Sabaody Archipelago with his companions and discovered a World Government ambush waiting for him. He sent Aixi and Sister Shaku away, killed the surveillance agents, and was struck by a Devil Fruit attack that aged him fifteen years.

• Luo Han left Fish-Man Island with his group while the Gorosei prepared a Devil Fruit ambush at his ship.
• Luo Han sensed the surveillance agents and camera Den Den Mushi near Island 20, then sent Aixi and Sister Shaku to Island 41 for their safety.
• Luo Han killed the hidden surveillance agents and Den Den Mushi as he and his companions landed aboard their ship.
• The Old Man with Black Mask and the Young Man with White Mask appeared above the ship, and the young agent transformed into gray mist to attack Luo Han.
• Luo Han covered himself with Perfect Armament Haki, but a trace of the gray mist entered his body and aged him fifteen years.
