INTO THE TREES: a tale of foxes and flames

A group of youtubers decide to organize an excursion for a video in the forest of suicides (Aokigahara) known to be haunted by the spirits of the souls of the dead. However, there is a Kitsune, a Japanese mythological creature, who sees them and attracts them with an illusion to punish them for their lack of respect. Towards evening, the boys find a corpse slumped against a tree and stop to resume the scene, when at a certain point the Kitsune appears and with an illusion spell distorts the space, separating the boys and dispersing them in the forest. One of the four boys, the protagonist, wakes up in the form of a spirit with a ball of fire instead of his head. Kitsune had turned it into a will-o'-the-wisp, called Hitodama.
