During a heavy storm, lightning strikes an ancient stone, chipping two pieces off of it. In response, the Wild Hunt appears, but with their leader missing, they begin roaming the forest randomly, much to Spriggan's concern. Meanwhile, Chise prepares to attend the College, but suddenly begins to feel ill. Elsewhere, a young boy named Gabriel has recently moved into the countryside with his parents due to his illness. That night, the Wild Hunt still roams the forest, their deadly aura killing every living being they come across.

Elias and Chise head out to find the horse's master. Meanwhile, Gabriel decides to name the young spirit Evan, and both begin exploring the countryside looking for Evan's home. Elias and Chise come across Titania and Oberon, who point them towards the ancient stone. Gabriel meanwhile becomes more self conscious about his illness which isolates him from other children, which attracts the attention of an evil spirit. Gabriel and Evan flee from the spirit and find their way to the ancient stone, where Elias destroys the spirit pursuing them. Evan is reunited with his horse and regains his memory and true form. However, the Wild Hunt does not respond to his summons. The group decides to rest of Elias' home until nightfall to search for the Wild Hunt. However, Gabriel begins to grow angry and jealous of Evan due to his belief that Evan prioritizes his duty as a part of Wild Hunt over their friendship.

As night falls, Evan summons the rest of the Wild Hunt as they prepare to return home. Wanting to bring Gabriel with him to free him from his frail body, Evan hypnotizes Gabriel into riding with him, intending to take him to their realm. Chise and Elias give chase, but have trouble getting close to the Wild Hunt due to their aura. Gabriel tells Evan that while he does value their friendship, he does want to return home. Evan allows him to dismount and return to the human world. The Wild Hunt return to their own realm, and Elias and Chise take Gabriel back to his home. Chise receives her new school uniform, and she wonders what the College is like.
