Suicide Circle Triligy?

[tachii]

I recently discovered that Suicide Club, and Noriko's Dinner Table are part of a film triligy, but what i have't found is the third film. Could someone please help me out and point me in the right direction? It would be much appreciated.

My apologies if this question is posted in the incorrect section.

The writer/director, Sion Sono, once stated there would be a trilogy, but no third film has ever been made.
