GT Fisherman's goal is 100 pounds (45kg) GT. If you're doing GT fishing, someday, GT fishermen around the world will dream of catching a fish of this size. And since you can't just aim and catch a fish, there's a strong element of luck, but in the case of GT, it's difficult once you catch the fish. It's difficult to even start, but you can only get the title by conquering a fierce battle from the time you start until you land.
After Koinobori's test, we were confident that this 100-pound GT was perfect. The captain was told by sight. It wasn't like that the moment GT came out, and it wasn't like that at first either. The GT managed to land despite feeling like it was about to be taken away by violent force.
He is also the driving force behind the completion of Koinobori.
