Synopsis:
Kain is transported into the world of One Piece. By a stroke of luck, he is rescued by Nami and eventually joins the Straw Hat Pirates.
At the same time, he acquires the Gray Wolf (Pleasant Goat and Big Big Wolf) Template, granting him the ability to invent all kinds of incredible gadgets and technologies!
From that moment on, the world of pirates is never the same.
Smoker: “Why can the Straw Hats’ ship not only dive underwater but also fly?!”
Big Mom: “The giant race I’ve dreamed of obtaining can actually be created with a single pill?!”
When a giant humanoid mech appears during the Marineford War, Vegapunk begins questioning his entire life’s work.
Could there really be someone even more brilliant than him?!
As if that weren’t enough, Kain goes on to develop powerful inventions such as the Hyperbolic Time Chamber, boosting the Straw Hat Pirates’ strength to unprecedented levels.
Faced with the admiring gazes of his crewmates, Kain simply waves his hand and says:
“Relax. This is basic stuff.”
