Literally all the people who know something --> let's get special powers to rule the world and defeat Imu.
Literally no one --> nah, let's get some Joy Boy (Shanks) tier haki, fruits are not needed --> not even Shanks imself says that lol.
Imu:
Joy Boy tier haki? --> doesn't give a fuck, let Shanks be
Nika/Niddhog Powers are found? --> let's fucking go to Erbaf right now and in person, our fight will divide the world.
