Review Detail of Ken_The_Destroyer in Chaaa

I remember it was a good fanfic But please don't repeat a mistake you did in previous, as It kinda was dragging the story down, at least for me, when you made a 'luffy dies then you all die' mission. It's not the mission itself, but rather the essence that OP revolves around Luffy only and if he's gone, then the world will collapse. This makes it feel like changing the plot by even a little, like Shirohige in GC is destroying the OP world. This is just my opinion you can ignore if you want, but just wanted to let you know what I think was the bad part
