haha funny how we all guessed pretty much the same thing... except I put my guesses in a PM coz I didn't want to take up space and annoy people.. coz my random messages annoy sum ppl..
Anyway, from what I have gathered
Miki is evil
That dude is really evil
Miki doesn't seem to like her job so I am going to assume she is being forced to do it
She is friends with Yoshi
I am going on a limb saying this but guessing that she and Yoshi and Aya were all working the same job, although it seems that Aya is out of the pic now as in either dead or just moved or something. Either way it's obvious she and Miki can't be together right now, in other words someone or something is keeping her from Miki.
Yoshizawa is still working like Miki (guess though)
Ai and Risa are going to become much more important in this story
One of the girls in the start is either Miki or Ai
The other girl is either Aya, Risa or Koharu
I am guessing Koharu is also evil
Another guess is that Koharu is the new 'Fujimoto' to Miki's 'Matsuura' or a baddie even bigger and badder than the dude if not the same as Miki but just really annoying
I am hoping Koharu dies but doubting it.
I think that Ai's dad either walked out on her or died or just divorced her mum and the mum remarried. BUT it looked like somehow both girls lived with the same dad and since Ai called him dad too and not stepdad Im gonna go ona limb and say he is her dad and something happened to Aika's dad.
Maybe he died or did the things I thought Ai's dad did. Either way their only connection is the same mum, which we haven't seen yet so is it safe to assume she died with Ai's stepdad? That's what I thought. I thought maybe Aika's parents died so her sisters' dad took her in.....
What else? ok, about Sayu and Eri, they will probably get together or die, either way it wont matter much because they are so not main characters but if I had to guess I would say that Eri gets Sayu and drifts away from Risa and Ai and then she and Sayu do teir own lil thing while Ai and Risa are dealing with the supernatural aspect of the story, meanwhile we don't hear abou tthem because they are together and busy hanging out together and not with the main characters or something.
Also I think Miki was in the same situation as the girl in the picture and Ayaya was probably the man that helped her (but she was a girl............unless she used the goatee/sideburn props

)
I think they were in love and something happened and they couldn't be together and that is one of the reasons why she is so reluctant to be a new girls' mentor/Matsuura thingy
Also I think a Matsuura in the way he meant it is a mentor who will teach someone to be evil and steal souls
Maybe they also steal hearts.... we only saw the soul bit but maybe the dude also fell for her. I dunno, maybe that is how she became one in the first place, falling for Aya... maybe that is why she wont be with her, because she fell for her and realised she was doing it to get her soul or to turn her. And even if she really loved Mii back, Miki could be angry with her all these years and that is why they are not together.... aww then poor Ayaya would be sad and lonely for centuries, waiting for forgiveness or somtheing
anywayz gtg mwah keep up the awesomeness! Luv yah
