If you want a spirit sword, you have to be the first one to find it. Do you really think the first person to come across a spirit sword wouldn't want it?! No. So if you're any place but first, you're not getting anything.
If you were lucky enough to be the first one to find the spirit sword, you should open up a small show (しょ) to show it off! And then you can make yourself the first in line every day to see the show.
