First, if you read this manga, don't be an idiot and keep relating it to Death Note.

I'm a Death Note fan too. You want to compare? Let me compare for you. We all know that DN is distinctly good but as someone who has read it all over again in both English and Japanese three times over I found a good deal of loopholes in the story, which I will list them down in a future review, simply because the story is too long and complicated for the author Tsugumi Ohba to handle. On the other hand, in case of Lost+Brain, the story is very compact, right to the points, and virtually free of loophole.

Okay, I strongly believe what makes most of you keep ranting about this manga, despite all the little interesting implications about hypnotism, is the very method the protagonist chooses to change the world - MEMORY ERASURE. Most of you may think it is unfounded, but no, it is exactly what had been happening in the world since the last half of the past century in the name of the neoliberalism crusade led by the U.S.'s economic mega-guru Milton Friedman, as described in details by Naomi Klein in "the Shock Doctrine." He craved for what he called blank slate of the society and the human mind, on which he can literally rewrite everything. Ewen Cameron was the world leading psychiatrist who share the same views and the two men's ideologies converged during regime changes throughout the world. In torture, human were made regress to infantile state, with their memory erased, mostly irreversible. Instead of hypnotism, which is more time consuming and requires extreme mastery, electroshock was used to erase memory and remake human.

I found a rather clear echo of the book in this manga. The bottom line is if you are good then you are more likely to do right more than wrong, so "as planned" is never a necessary phrase to blurt out any more and things should just go smoothly, even though it went all wrong in the end because of a single mistake. That's the narrative that Lost+Brain chooses, to let us follow a well-planned operation until its very end without inserting too much unnecessary twists to confuse readers. The ending might be kinda bad though.

You should read this manga if you are a disciple of LOGIC, not a disciple of some "death note cult."
