The youkai curse Taki that he will eat every 13 person that Taki mentioned their names if she unable to find her in 365 days.
A month before the due date, the youkai finds out that Taki have ask for help from Takashi Natsume to search for him. Since Natsume is able to see youkai on his own, without any circles or outside help, the youkai despises Natsume for this.
