Ah, beginning of the next arc.
Parallel universes, being not parallel, and sharing a radiating point... I see... 'Central' Academy. I used to have a concept like DZ in one of my past works, called Infinity Plains... Um, never mind. It does fit you well.
Heartbreak Spirit, though. Sounds like an important villain. So early into the story...
8 nyas in the a/n. :3

LOL. Fai, the crazy, little, jealous boyfriend! *shot*

I knew instantly that Miki will get herself lost. She seems like the type who very random and go where the wind takes her.

If that girl calculates everything Miki says her brain will implode. :)

I'm still not getting the counting in the beginning. I'm sure it will explain itself, soon. But what the hell? Eterno is the one laughing for once? Like I said earlier, I enjoy their chemistry.

Demigods? You mean, half-gods? Wow. The number of supernatural beings are endless, especially with the cross-breeding. But how did Professor Dizo know about Miki's ghost investigation? Psychic? Or is Eterno reporting to him?

Oh, my. Is this the perspective of the "ghost"?

Ironically, Miki's and Eterno's opposite personalities go together well. Their interactions are entertaining. I also like your descriptions of the DZ city, too; the eccentric artist part, that is.

597 is empty? Why do I see knew and interesting neighbors in the future?

Oh, dear... Secret Agent Miki is back!

Seventy-four universes? Are we going to visit any of them? If so, did you have to write them all down so you can keep up with it?

I guess that best time to get vandalized is when your personal possession haven't arrived, yet. I do wonder who Miki's family are going to react to her new school. What about parent-teacher conferences?

Oh, well. I'm just babbling. I'm sure you have it figured out. I can't wait to see more denizens, though. The possibilities are endless.

I had a feeling that the activation was something sensual. Poor Eterno.

Miki is odd, realizing she's face-to-face with a demon and not the least bit concerned. However, I can't tell if she figured it out from her over-active imagination or if she truly does have a gift. Eterno and Professor Chio have an amusing relationship, too.

Talent unknown? Is that a foreshadow?

I've forgotten who she is XD

I may have to reread all of DZ at some point because I am beyond lost. Maybe a recap every 15-20 chapters or something?

I've gone coo-coo for coco puffs! .

The writing style is fine. Maybe I just shouldn't pick up where I left off about 10 months ago though

I'm very confused between the last chapter and this one. What's going on? Maybe we switched characters or something. It has been a while since I read XD

A cute ending to the arc. I'm glad nex didn't do something as pathetic as to deny his obvious guilt the moment he was caught. I would have lost absolutely all (what little there already is) respect for him if he did. Now where are you going to go from here then?

I have just one thought from this conclusion, just why was miki targeted? She certainly doesn't have higher grades than nex and she wasn't even a student at that point. Hm is the mystery really fully solved?

Wow my wild guess was spot on. A little bit of a sad story. But you did well to get the point across, but how does this have anything to do with what he did? Well I'm guessing next chapter will answer this question. So without further ado.

The audience has gathered with eterno with them. You really are good at dragging things out kisho, but it made me laugh seeing each characters individual mission. I'm guessing Miki is going to be the lead in the announcement then.

My money is on nex being the spirit, don't know why though. Now what are they starting, I'm dying to see the conclusion and the moment I think it is, it isn't. Very well written as usual.

Judging from miki's reaction I'm guessing selene is innocent. But she is definitely hiding something or other. I'm hoping next chapter is reasoning chap. *Reads on*
