I'm not sure why many gave bad rating from Chapter 120 onwards.. Yes, there's alot of technical terms, new people from other manga (Jesus and Shield of Aegis - I didn't read any of them). But the whole story still progress in a great way.
The manga is overall really good and addictive. Every character has their own storyline, even the tiny ones.
Remember to read editor/translator/scanlator (not sure who wrote them) comment at the end of every early chapters. They're simply not to be missed!

I read at least three comments stating how they didn't understand the new characters and the plot. This series is a sequel! Read Yami no Aegis and read Jesus. Don't be the idiot who complains about not knowing back-story when the back-story has so convrniently been scanlated for him for free!

I started to read this because of the art but man, if the reason is the art only, a reading material ain't worth wasting much time. On the side note, I rarely read action or seinen for the reason that manga fights scenes/panels most of the time left me hanging for details so I rather like to see the fight scenes animated. In this case, the fights scenes were drawn effectively that someone like me who shy away from this genre got engaged till I can't control the urge to read chapter after chapter. Pack with action, tactics/strategies told in here keeps me going until I reach the latest chapter scanlated so far which is 96. Truly, when art and story merged together produces an excellet reading material to get one hooked that you can imagine. High recommended!

I really liked the beginning and believed it had very good potential.
But then it slowly turns into a battle manga. Right now as of chapter 123 it is a full out battle manga with the past few chapters not really making any sense. I am very disappointed but i suggest you read the first couple of volumes but when wiseman shows up that is the time in which it slowly starts to turn into a battle manga
on a side note the physics of this manga also slowly gets thrown out the window but that's not that much of an issue with me

Man~, this one makes me harder and harder to criticize, even in little details, as it goes on and shows itself as far as this much involving all that spy and/or underground thingies. And, I can truly say one thing to you: the author(s) did damn deep research on them and presented them so convincingly. Although, I can't really say that they have done it cleverly enough, to the extent, I can sincerely applaud for their ingenuity, but I think it's the most well-informed and well-constructed story in overall that gradually hallucinates its readers to its own world. I might have made a bit exaggeration there but after reading up to the current releases, it rocks!

Here and there, I did feel flimsy on some details due to familiar jargon that I thought I knew, but, well, they were convincing enough. Anyhow, try it out! It's enjoyable especially if you like some cool stuff.

After reading all of the positive reviews given for this manga I decided I had to read it. I was quite un-interested in the manga when I began reading, only after about 20 chapters did I finally start enjoying it. The story is decent, it's not a great story, it's not creative or new, but it's enough to keep you going. But I'm guessing that I'm not the only one here that doesn't read UDDP for the story. I read it to see where this romance is going, but mainly I read it to watch Mamoru kick ass and take names. He is an expert in the "ass-kicking" category in my opinion. ^.^

you have to read this !!! it's so good !!!! lot of action. nice drawing, and good story

to be completely honest i only looked at this manga because the cover caught my attention, i wasn't going to read it because it didn't sound too interesting too me, but.... i read it anyway..... and guess what? I'm totally in love with this manga!!! just cant get enough of it!
great read the plot is extraordinary and the characters are the most well made Ive ever seen
recommended 100% no over exaggeration ether, its just that good

Up until the last few volumes I would have given it a six or seven. However, it is becoming more and more like Berserk, one of my favorite mangas, except with sci-fi instead of magic. We have a scarred swordsman with a dark streak a mile wide and a heart of gold. We have a tiny little witch (in this case the psychic) who is his partner. Seperate, each is strong. Together they are invincible.Surprised no US company has picked up this title.

this is the best manga ever! seriously. the plot just drives you mad with anticipation for the next ones and the art is really really good!!!
and the girl in me is looking forward to mamoru and haruka's relationship in the future...;p
