When the socially awkward former Water Pillar Tomioka Giyu suddenly travels to the world of One Piece and is forced to bind to a baffling "Interpersonal Communication Manual" system, witnessing the Straw Hat Kid on the execution platform, about to be executed by Buggy, saving him, breaking the platform, and becoming entangled seem like the natural progression. Luffy: "Wow! What a cool move! Be my partner!" When the taciturn Giyu encounters the most free-spirited pirate group, this sea is destined to be turbulent by the least chatty swordsman. ... "Let's have a party, Giyu!" [Interpersonal Communication Manual] [Target: Monkey D. Luffy] [Status: Extremely Excited] [Preferences: Throwing parties, hanging on to the host] [Suggestion: ... (Analysis impossible)] Right now, that rubber boat captain is swinging from my only arm. What should I do now...

Travel through the world of pirates, carrying a treasure appraisal system with you. An apple was identified as a Devil Fruit. A gold coin was identified as a Destiny Coin, which can withstand three fatal attacks. Ace's necklace was identified as the Entei Necklace, doubling the wearer's fire power. The beads can be manipulated to transform into giant fireballs that chase enemies, and any enemy hit with the beads restores health. The Alabasta Golden Scepter was identified as the Horus Scepter, allowing two or more Devil Fruit-bearing objects to exchange their Devil Fruit abilities. This can only be used once! Smoker's cigar, Nami's weather stick, and Usopp's slingshot all underwent dramatic transformations after being identified. So much so that Im exclaimed, "A fruit even more powerful than the Sun God Nika has appeared!"...

After his defeat on Onigashima, Kaido, submerged in the seabed's lava, opened his eyes and was reborn in 1484, serving as a trainee on Rocks' ship. The God Valley Incident was about to unfold! "One bad thing after another. If defeat by Joyboy is fate, then I will tear it apart!" Kaido picked up the Eight Saber Rings, and with a wielding of his Domineering Haki, he blasted the mountain to smithereens. A Devil Fruit awakened? Enveloped in Domineering Haki, he could see and kill! Only Haki could forever stand at the top of the world! In this age of brilliant heroes and powerful warriors, Kaido must rely on his own strength to challenge Roger and Whitebeard and make up for the regrets of his past life!

Remos traveled to the world of pirates and activated the destiny simulation system.

As long as you follow the concept of destiny, the degree of fit will continue to improve, and you will walk on it and become a destiny traveler.

"My first destiny is hunting? Very good. From today on, I'm a sea ranger... Hey, that title is quite fitting."

Remos blew on the muzzle of his gun, threw the bounty order on the pirate's body, and said with a smile.
