I watched the drama first. Then I read the manga.
First of all, I must say that I love this manga a whole lot. It has pretty nice twists and turns. Also I like the art work. Well, actually, I have a soft spot for badasses such as hackers or assassins, so I naturally like this story.
Comparing the drama and the manga... Manga is much better in my opinion. The character of Fujimaru in the manga is fairly different from the one in the drama. I like the the Fujimaru in the manga a lot more. I'm not saying that the actor in the drama didn't play out Fujimaru well. He did fine. It's just that he portrayed the character in a different light...more like a coward? and his expressions are kind of repetitive. (Miura, the actor, is pretty cute)
Anyway, if you are deciding between the drama and the manga. Manga is much better.
Enjoy!

I just caught up after not reading it for so long (reading 40 chapters in 2 days). The plot will get more and more complicated as it goes. I'm not going to say a whole lot because i don't want to give anything away, but man... i'm impressed. this is one of those mangas that turn your point of view around again and again. bad guys are not really bad and good guys are not really good. the situation is not really the real thing. and the problem just got bigger and bigger as each chapter passes. Of course, the main character develops very well.
all in all, i still love.

An amazing thriller. A manga soooo good, it's more addicting than crack ! I get withdrawal symptoms after only 4 days of not reading any !

It reminds of Deathnote (love) for some reason. Probably because this manga also offers planning, scheming, masterminding!

Hilarious how the villans in this manga are Russian, and in real-life, the most lethal Hacker-Criminal Organization is Russian lol

CoCo love's this Manga's MoMo!

This manga is nice, it is intense, suspense and is sort of a thriller too.
For those saying that the technical know how of this manga in regards to hacking should understand the author and artist are not hackers and even with research their knowledge would be average at most.
I enjoyed reading this manga esp when it comes to the twist, suspense and intensity. Pls dont judge it from the technical aspect.I also adviced anyone enjoying this to check out the bloody monday series which is quite interesting although slightly different from the manga

...the "high-end security" in this manga makes me laugh. The obvious one is the MAC adress...LMAO, that thing can be traced easily under 10 mins

Overall, i like this manga & the story/convo is pretty intense @ sometime...except some supposed- to-be "high-end security" stuff here

Okay i liked the story, the characters all... but the sense of the main male character... lol
actually i like his personality but he's kinda messed up

Super addicting. Very suspenseful and pretty nerve-racking. I will just leave it at that for now. Just my opinion but if you are reading these comments to see if you want to start this series, just read the first few chapters and decide for yourself.

all you guys are talking about how you have such how tecchie credentials and that all he could do was a trojan... well u guys are retarded.....
Sometimes the best solution is the simple one, not the flashy one.

The plot about the "bloody monday" stuff was not bad and rather interesting like "what are their plans or motives for unleashing Bloody Monday?" However, the so-called "computer intelligence" of all the various characters involved was quite low-level. After all, "social engineering" is the easiest and fastest way of obtaining and confirming data and information and any seasoned hacker(black or white) would never confide in an "outsider". Plus, a seasoned hacker usually has their own set of hardware and software(either DIY or purchased), in the event of various emergencies.

And methinks the naivety of the various characters casts certain doubt on the direction of the plot since harebrained decisions and motives would be a total disappointment, given how important some of these people are.

The art, btw, is pretty good for an action manga and the pacing of the action scenes is decent. In essence, read this if you really crave for a main character who's a hacker and if you have low expectations for the story.

its a great stroy and i like it very much, but the main character makes really stupid mistakes and i cant say wat the are cuz its gonna be spoiling it. but for a super hacker he makes really easily avoidable mistakes if he only thought about it. also for a super genius he fell for a easy trick by tht teacher...i mean come on dude your smart, u should hav out-think the teacher.

anyways did the translators drop the manga or are the busy wit other mangas cuz this has 6 volumes but only 6 chapters are release...well im jus wondering


updated...i cant believe he is so stupid for a super hacker...he needs to be cautious bout "outsiders"(i.e. teacher), jus dumb

for anyone obsessed with computers and hacking, this is awsome. yeah he included his friends, but he didnt know into what until. 5 chp so far, but i like it. i give it a 10. he may seem stupid but he was clueless. its like that starting out in all manga. learn some judgement restaint till chp 10. in america, no 10 yr old is like that. damn. i may have been hacking at 10 but i also didnt have any friends till high school.
