Ringu, but the curse is mentally ill teenagers It gave me a kind of Ringu vibe, where people need to keep passing the curse to another in an infinite cycle. Saya did the same as Mitsuko (all the others), survived a mass suicide and must create her own suicide club, becoming a new Mitsuko and passing this curse on to the next girl who survives the suicide, which happened to Kioko. I thought the manga should have evolved more. Kioko narrates the events before the subway incident, and ends up investigating what Saya is doing. What we imply is that in the end she carried this "curse",since she survived the fall, but the manga ends right there, without evolving and giving a concrete ending.

I feel like the manga was missing something, that it was just a fair ending and that it wasn't an open ending. It could have shown who the first Mitsuko was, how it started, etc.
