I really hope they show off November Rain's full stand page next chapter, I'm really curios as to what the stand did to get rid of the threads since the only thing we know is that it makes things heavier. Also kinda expected pink guy to betray the group but no this quickly.
I think it removes weight/matter from whatever it hits, at least temporarily.
Like the first chapter, the cops skin didn't pierce, but started evaporate with each rain drop. I assume they return to the original location after a while if exiting stand range/stand deactivation.
That's the extent of my "knowledge".
I don't see enough of the stand ability to know it's potential.
It looks like a close range stand, maybe medium power like Gold Experience, but maybe not as strong as Star Platinum strength wise?
I wish more JoJo's could have had more than just close range punch barrages plus some magic power. This one looks kind of interesting, but it's still not a different stand type.
