Questions for Onikakushi-hen (what really happened, I mean)..

Spoiler for .:

1. Why did the van with the yamainu guys try to run Keiichi over?
2. Why did they chase him after he ran away from Rena?
3. What happened to the ohagi? I can't remember if his parents were still home, so this question only needs an answer if they weren't.
4. Why was Rena pulling on the chain in the first place, especially if he was yelling at her?
5. Why did Rena have the machete in episode 4? Was she trying to show him that she'd protect him with it?

Questions for Watanagashi-hen/Meakashi-hen..

Spoiler for .:

1. When Rika had the syringe, what was in it? The same thing Satoko uses for Hinamizawa Syndrome?
2. Why would Keiichi be dumb enough to go outside and see Shmion when she clearly told him not to?
3. Why did Rika get so weak after being injected with the contents of the syringe?

Questions for Tsumihoroboshi-hen..

General..

Spoiler for .:

1. Is Hinamizawa Syndrome real?
2. Is the "queen bee" story true?
3. How can Keiichi get Hinamizawa Syndrome?
4. Did Shion get Hinamizawa Syndrome or was she just crazy/obsessed?
5. What happened to the one person believed to still be at large from the dismemberment murder?
6. How was Hanyuu able to become human?
