Ch. 354Young Powerhouse

Li Xiao became the youngest S-rank powerhouse after winning the World Martial Arts Tournament and challenging Whitebeard, then sought a fight with Mousse. Mousse demonstrated the overwhelming gap between them by knocking Li Xiao unconscious with his Conqueror's Haki, but Li Xiao woke up excited rather than discouraged.

  • Praline trained after her earlier defeat, but Li Xiao won the second World Martial Arts Tournament by defeating her, Red-Haired Shanks, and Hawk Eyes Mihawk.
  • Mousse praised Li Xiao's rapid breakthroughs in Haki and judged him nearly equal to Whitebeard and Garp.
  • Li Xiao challenged Whitebeard on Hachinosu Island, then ended their fight after recognizing Whitebeard's declining health and deciding he would win if it continued.
  • Li Xiao went to challenge Mousse, who refused to fight under conditions that would make the outcome one-sided.
  • After Li Xiao insisted on trying, Mousse released his Conqueror's Haki on the Red Line and knocked him unconscious; Li Xiao woke up excited.

Ch. 355A Twenty-Year Promise

After Li Xiao endured Mousse’s Conqueror’s Haki, Mousse promised him a head-on rematch in twenty years, giving him a goal that would also keep him from causing trouble. Mousse then reflected on Yamato’s escape from Kaido and how she had lost her tournament savings after facing Li Xiao.

Ch. 356What Did You Do with It?

  • Mousse called Praline and decided she would travel with Yamato aboard his newly built ship, taking the children in his care along.

Ch. 357They Just Don't Know How to Appreciate It

Mousse took Brulee to the East Blue so strangers could judge her third eye without being influenced by their family’s reputation. At Baratie, Sanji praised her eye for the first time, and Brulee wept with joy.

  • Mousse comforted Brulee about her third eye and invited her to travel with him to hear honest opinions from people outside the New World.

Ch. 358As Expected of You

Mousse brought Brulee to Baratie to see how Sanji would react to her, and discovered that Sanji’s Observation Haki might overcome the fear inspired by her third eye. After Sanji made Brulee finish her leftovers and then cleaned her plates himself, Mousse revealed himself and reunited the two men, while Brulee learned Sanji had once nearly been taken to Totto Land.

  • Mousse realized that Sanji’s lack of fear toward Brulee’s third eye likely came from his powerful Observation Haki, and wondered if that ability had once countered the Three-Eyed Tribe.
  • Brulee admitted she had ordered too much food and offered to pay double, but Sanji insisted that wasting food was wrong and made her eat the leftovers.
  • Brulee cried that she could not eat any more, so Sanji sorted the untouched food for later and ate the portions she had already bitten.
  • Mousse revealed himself, laughed at Sanji for cleaning the plates, and delighted Sanji, who greeted him warmly.
  • Brulee learned that Mousse and Sanji already knew each other and that Mousse had once nearly brought Sanji to Totto Land; Sanji remembered that choosing otherwise had led him to Zeff.

Ch. 359Teach's Tears and Kaido's Death

Mousse advanced global trade and education initiatives while Marshall D. Teach led the Whitebeard Pirates to invade Wano and defeat Kaido. Momonosuke killed Kaido, but Kaido’s final blow killed his chief retainer as he protected him.

  • Sanji remained grateful to Mousse for helping Reiju escape, while Zeff declined Mousse’s offer to have Law restore his leg and discussed relocating Baratie near Reverse Mountain.
  • Mousse proposed a World Trade Organization, and the Flower Kingdom agreed to abandon its isolation after Amon reshaped its terrain to improve farmland and protect against disasters.
  • Mousse advocated for a global Education, Science, Culture and Health Organization, and the Whitebeard Pirates supported the plan under Marshall D. Teach, who had received the Dark-Dark Fruit from Whitebeard.

  • Momonosuke killed Kaido with a powerful slash, but Kaido’s final club strike killed Momonosuke’s chief retainer as he shielded him.

Ch. 360Spade Alliance

Mousse assessed the shifts in power after Kaido’s death, including Blackbeard gaining Kaido’s Devil Fruit and the proposed marriage alliance between Blackbeard and Momonosuke. He concluded that the alliance would strengthen the Whitebeard Pirates but still leave them far behind the Charlotte Family’s forces.

  • Charlotte Linlin woke from a nightmare in which she had never given birth to Mousse and she and Kaido were defeated by a young man in a straw hat.
  • Mousse learned that Marshall D. Teach had obtained Kaido’s Azure Dragon Devil Fruit and warned his Second Brother to master the electromagnetic cannon.
  • Mousse was shocked to hear that Momonosuke planned to marry Blackbeard, then reasoned that the alliance could secure Wano Country’s future and benefit both factions.
  • Mousse considered the forces Momonosuke would bring, including Wano Country, Zunesha, and his retainers, and recognized that they could help Blackbeard consolidate power.
  • Mousse compared the Whitebeard alliance with the Charlotte Family’s strongest fighters, elite ranks, and armies, and judged that the Charlotte Family still held the advantage.

Ch. 361Back to Being a Slacker

  • The Charlotte Family’s growing alliances and Ace’s decision to join Bartholomew Kuma’s New Revolutionary Army left Blackbeard as the Whitebeard Pirates’ uncontested successor.
  • Blackbeard used an international organization to help search for the Poneglyphs, hoping to learn the secret of Laugh Tale before the Charlotte Family could widen its lead.
  • At Laugh Tale, Blackbeard learned that Pluto could not reach its full power and that defeating Uranus required Poseidon, while Mousse and his allies already held the advantage.
  • Li Dayong arranged for Li Xiao to challenge Blackbeard, and she beat him unconscious despite her doubts about why she had to fight him.
  • Blackbeard abandoned his ambition and stayed with the Whitebeard Pirates, whose crew was spared the turmoil that might have followed his departure.

Ch. 362Different Strokes for Different Folks

Ch. 363One Sea, One Nation

Mousse’s perpetual-motion technology transformed the world, helping establish public ownership and unite much of the Pirate World under the “One Sea, One Nation” vision. As the West Blue teetered toward chaos after Li Dayong’s death, Li Xiao’s show of strength against Katakuri only made his former brothers more determined to eliminate him.

  • Luffy sailed around the world three times, while Nico Robin recorded the upheavals in her book 1080° Around-the-World Voyage.

  • Reiju seized power in Germa 66, after which Mousse supported the unification of the North Blue.
  • After Li Dayong died, Li Ya turned against Li Xiao, who defeated Katakuri to intimidate his former brothers but instead made them more determined to kill him.

Ch. 364Everyone like a Dragon

Mousse rescued Li Xiao from Li Dayong’s sons and disciples, then fought him atop the Red Line to test their strength. After revealing his mastery of Conqueror’s Haki and explaining his vision of a society where everyone could become powerful, he left Li Xiao struck by how closely their ideals aligned.

  • Mousse arrived as Li Xiao faced four S-rank opponents, knocked them down with Conqueror’s Haki, and stopped Li Xiao from taking revenge.

Ch. 365Ideal World

Mousse’s world transformed through communal child-rearing, public ownership, scientific progress, and full automation until material scarcity disappeared and society expanded into space. He remained convinced that extending his life had been necessary to protect the changes, and the story ended with him having achieved his ideal world.
