I have not seen the anime but by the previous review I need to.

The story revolves around revenge which starts out with the scarring of a woman's face. The MOST HEINOUS crime of all of Asian culture. Her attacker provokes her by saying she deserves to live the scars cause she will always think of him when she sees them. She will get revenge in exchange for her own soul going to the same place she is sending his.

Thus begins the never ending cycle of revenge Japan loves to showcase. "When seeking revenge, dig 2 graves".
There was no lead time between each incident, thus it felt cramped and hindered by the short time span of the movie. I had no context who the four harbingers were that accompanied lady death. Its Time passer, but only if nothing else is available.
