Help needed!

I have some pertanyaan about the PV's. anda don't need to answer all of them, just ones that anda know atau have a legit theory for.

Yobanashi Deceive: Is the "monster" Kano speaking about one of Azami's snakes?

Yuukei Yesterday: When she's running because she needs to tell Haruka something, why is she dressed as the Headphone Actor? I thought Actor's goal was to get to the hill.

Headphone Actor: This one really confuses me. Where is she, even? Is she in the Kagerou world, atau some dream, atau just in the real world with people testing on her? atau is this just the video game character's story? So confusing! :(

Jinzou Enemy: is this song about Ene and Shintaro, atau Ene and Headphone Actor, because there are two different video that both make sense.

Otsukimi Recital: How did Hibiya get out of the time loop? Did someone just decide that he should go back? Also, what happens to Hiyori? Does she keep dying, atau does she just get to chill there?

Shounen Brave: Do the people Seto encounter say the things out loud, atau does he read their minds? Same pertanyaan for Mary.

Outer Science: OK, I'm super confused about the routes. Which comes first? Does Mary reset the time all the way from the beginning, atau up to a certain point? Does she remember that she reset it? What happens to Kuroha when it's reset?

lost Time Memory: Does Shintaro go to the Kagerou world? Why is he encountered oleh Azami? Does the end of the song tampil Ayano's ghost? Does she come back?

Summertime Record: Does Konoha turn back to Haruka, and wouldn't that give him amnesia?

I think that's it. -,-
