Wind of Inari is an Exploration technique that points the Guiding Wind at Fox Dens. Follow the fox to an Inari Shrine for extra Charm slots and Charms you can upgrade.
You set the Guiding Wind's target from the map screen, then follow the breeze. It saves you waiting for a Golden Songbird to lead you.
Charm slots are what make Charms useful, so finding every Inari Shrine pays off all game.
