If you see a spirit with an axe, you better pray for your life. Spirits only hold axes if they're thinking about murder, so pray as hard as you can to try and get it to spare you.
You pray and pray and pray and nothing happens. You stop praying and dare to open your eyes. There is a key (き) in front of you. Grab the key and hold it before you and pray for the spirit to take it. Moments later, both the key and the spirit are gone.
