So I was watching the anime's fantastic version of that scene and noticed the "sky parting" effect. Apparently it is seemingly in the manga, just understated compared to the anime.
Thing is, we've only ever seen the sky parting as a result of two powerful conqueror's clashing equally. If the knot is supposed to be Joyboy's haki alone, how does it make sense for a single person's haki to do this? Joyboy tells Emet it's "(my) greatest haki", but what if there's more to it than that? I somehow doubt the narrative answer to this is going to be something as boring as "Joyboy charges a rope with haki like a battery"... so what about this- it's not "just" Joyboy's haki. It's a conqueror's clash sealed away to conclude in the future, basically "capturing lightning in a bottle" from a conflict centuries ago that never resolved.
I'm willing to bet that if this is the case, it's a clash between Joyboy and Davy Jones that was stored in the knot. Aside from apparently Imu, there aren't really any other contenders
