Background
Who placed the repeating curse upon me?

The video shows Miku who, for reasons unmentioned, holds a grudge against MEIKO and attempts to lay a curse on her by means of ushi no koku mairi. However, after she's finished nailing the straw doll to the tree she gets stabbed by an unseen force and dies. It turns out MEIKO had also had been using ushi no koku, and managed to start atleast a day earlier than Miku.
