Those Who Hunt Elves S01 E08 The End Of Life! Until The End Of The World

Junpei and the others have found an Elf. However, there is a problem, for the Elf in question IS a ghost! After some doodling around, Celsia manages to put her into a body, but, to their surprise, the much sought incantation is not on her body. To make things worse, there was a screw up with Celsia's spell and the gang cannot go back into their bodies again.
