Lets see if i can come up with a few questions that popped into my mind as i read this:

- Any theories as to why Tsukume is the only one who can remove the rosary? That "in sync" explanation inner moka gave sounded very sketchy

- Was Ruby always a masochist? Because it came to a complete shock to me when Yukari brought it up in the doppelganger arc

- Has anyone else considered that the bus driver might be the third of the three great dark rulers? It's crossed my mind a couple of times...

- What's the deal with Hokuto? Good, evil, what?

- Who are your favorite girls?

... i'll think of some more eventually, i'll leave you with these for now
