Spoiler:

Rule X is basically someone will go crazy in each arc. Rule Y is Tomitake and Takano's death, and Rule Z is Rika's getting Watanagashi'd followed by the Great Hinamizawa Dam disaster. So does that mean that once Rule X + Rule Y happen, it will ultimately lead to Rule Z?

In this arc, everyone is busy trying to prevent Rule X from happening. Despite that, it's important to prevent both Rule X and Rule Y from happening in order for Rule Z to not happen. However, Teppei is literally a bad "piece" that can ruin a world even if Rule X never happens. Is that right?

Actually, it's:

Rule X: Someone will be paronoid, suspecting everyone of hiding something (leading to murders)

Rule Y: There are some hidden, outside influence.

Rule Z: The Sonozaki seems to be center of the "curses," which feeds Rule X.
