From Endless Abyss:

This is the story of a very smart student called Hirama Ren who is used to always getting the top results in his school, and is the chairman of the student's council. One day, he walks past a group of bullies and asks them to leave--and because of that, they decide to teach him a lesson. They decide to beat up a couple of guys and they reported it to the teachers, blaming him.

Hirama becomes enraged by it and so he decides to attain some power that could allow him to change the world to a world that he wanted; one without such pathetic people.

Coincidentally, his vice-chairperson called him and asked if he was fine with her inviting a hypnotist for some event at school to hype up the school population. Thinking that the ability of hypnotism is just what he was looking for, he agrees to it. During the "trial" test of the hypnotist's ability, he set up some plan and later on used it to test if hypnosis was able to hypnotise people who were avoiding it. With his new found knowledge, how will Hirama use this new power to reshape the world?

At first I was interested in the series when I first saw a couple of pages for ch01. Then as I read on and read the summary, the eerily similar plot just made my brows twitch. Not just that, the character looks like Light/Kira too! Reading the first chapter didn't convince me enough about this series... Maybe if it was a different setting and motive or goal, it might have been different. Now, it just reminds me too much of DN.

I like this better than Death Note. No surreal death gods and a magic book ~
The art is good, the plot around hypnotism is interesting as well, the characters are interesting enough to hope something happens.
There arent many mangas like Death Note so be happy that theres another one as good.

The authour didn't make full use of the theme

While the theme about hypnotizing people to "destroy their weaknesses" was interesting, this series lacked logic. Hiyama's actions were extremely stupid for someone with such a power:
1> When I read the first chapters, I thought that Hiyama was going to be the hypnotist's disciple. He would have grown to become a great hypnotist while secretly executing his master plan. But no, the author decided to make him stand on his own. How could Hiyama be able to master hypnotism all by himself if many in the field, including Kuonji couldn't?
2> The suicide bombing: Irrational. If you are someone with such power, you don't reveal it to the public. We can see that later on, this attack will have serious consequences to Hiyama's plan. If he hadn't made up the attack, Kuonji wouldn't have noticed his power. He should have controlled goverment leaders and use them to make changes. Or perharps the author should have made him go to war-torn countries to stop conflicts and make himself a god-like figure.
This was a huge mistake. Didn't he know that he will be isolated from the rest of the world? And in the worst case scenario, the US may even attack the place with an atomic bomb! Think about it, in such a situation, the world would already been in chaos due to the shock.
4> The Bluebird Project:
His deduction about this project just proves that in the manga, the US may have acquired hypnotic power, maybe beyond that of Hiyama. But then again, it would mean that Hiyama would have to battle US's experts in hypnosis, which didn't happen. Too bad.

It's different.

Yes it was obviously inspired by Death Note and Code Geass, both series I loved, but it is hardly a 'cheap imitation'. That's just an immature comment from Death Note and Code Geass fanboys (or fangirls). No media should be judged *because of* the media that preceded it. The story's different, obviously.
Spoiler (highlight to view)
The main character's ultimate goal is different - he wants to eliminate the weakness in men's hearts, not merely suppress the 'evil' of society, he wants to change mankind from the ground up; the methods are different - hypnosis, he uses hypnotic suggestion not only to achieve objectives as in Geass, but to change the people themselves;
and the exploration of the human mentality is deeper. I believe that it's a manga that stands tall on its own.

Well, if you liked Death Note and Code Geass, then you`ll probably like this one. About a genius student who`s tired of the world and wants to change it (DN). Then he learned hypnotism, and used it to control, etc. people (CG). Well, so far, so good. We`ll see how it will develop.

Author makes the opposition too weak to make Hiyama seem intelligent instead of allowing both sides to have intelligent people and then have Hiyama be yet more intelligent. It has some interesting theories on hypnotism and the human mind, but they feel more and more far-fetched as the story progresses.

Even though I've never read Death Note before, I understand the basics of L, and seriously...the start...was totally Death Note styled. it isn't horrible (for someone who hasn't read Death Note) but still okay, slightly interesting. And then it went on, and all the weird stuff came out, the hypnotism theories...and my brain dies. Usually I like these kinds of manga-with all the interesting theories-but this one was simply overloaded (similar to Qualia the Purple, in terms of theories) and the text and background ain't exactly friendly on the eyes. I mean, black background and tiny words all crammed together?

The story is also quite unbelievable-the main character's motives are questionable (or more like, questionable for a teen his age) and the way he goes around achieving it is strange. Though I'm only on chapter 3. I feel the character's overlap, and the overall effect isn't so pleasant.

This manga is okay, overall...just gives me a hell of a headache, which in this case, stretches on for too long. I'm gonna have to drop this one.

The entire time I was reading this I could only think of Light from Death Note..... Only Light was a much more rounded character. You could really understand the character, unlike Hirama...

Emm... Shounen genre is a bit too straight forward for this plot, I think. It's not bad, but somehow the pace kills all the mystery and some of the dialogs are awkward.
It's too dark for it to be fun(protagonist is a sociopath), and too childish to take it seriously(hypnotism is a suggestion, not a remote control).
well, maybe I expected a bit more.
