Teenage genius Hiyama is fed up with the world: daily life is boring, and everyone around him is little more than living filth. One day, after a particularly trying day of tolerating the human scum that populates his high school, the boy decides that the only logical solution is to completely destroy the world and all of its useless creatures, then rebuild it as he sees fit. To this end, the teenager starts dabbling in hypnotism, and in a matter of months has half the school and even part of society under his control! However, this violation of free will won’t go unchallenged: another highly skilled hypnotist is determined to outsmart and stop Hiyama. In this dangerous game of cat and mouse, which man has the intellect to outwit and outmaneuver the other?
Power corrupts, and absolute power corrupts absolutely. Top-ranked student Yagami Light is disenchanted with the world around him. Through a series of events, he comes into possession of the ultimate power over life and death: a supernatural "death note" which can kill nearly anyone at his whim. As Light sets off on a crusade-turned-killing-spree, investigators from a police task force try to stop the mysterious deaths - including Light's own father, a senior policeman.
The main character of both stories is a genius student who wants to change the world along to his thoughts, using his average intellect, his friends, the girl who loves him, and killing if it's necesary.
In the begining, both main characters are genius students bored with their lives until they get a "power" who make them able to change to world to a better place (in their own opinions, of couse) - also, both are egocentric and take some false steps due to their big ego and psycho state of mind.
If you liked Lost+Brain, you'll like Death Note. Both are about a young student wants to change the world. Some people find them the evil and therefore an adversary representing the "good" will appear and fight against the "evil", but there are also some people who finds the young student doing the "good". It's all a question about your own morale and etiques and how far you're ready to go to achieve your goal.
In 2010, the Britannian Empire enslaved Japan after a brutal month-long assault; in the aftermath Japan was renamed Area 11, and its people began a hard and terrible existence. Lelouch, a Britannian student living in Area 11, has grown up hating the Empire and everything it stands for. One day, while investigating a crashed military plane, Lelouch meets a mysterious girl who grants him the ability to control minds. Can he use his new power to fight for freedom, or will his hatred twist his good intentions into mindless acts of vengeance?
Both main characters are high-intelligent studants who can control other people's acts and choices, using it in their own intents to make the world a better place. As Schneizel stated in Code Geass, the geass power can be considered a very strong kind of hypnosis - and that's exactly what Ren does in Lost+Brain. Both of them are bored with the world around them (although Lelouch have a real reason to seek for revenge and Ren does not).
Takao Kasuga is a lonely boy who spends his days immersed in books to escape his frustration with life. His only source of joy is the beautiful Saeki, who he secretly admires from afar. However, Takao's obsession goes too far one day when, in a moment of emotional folly, he steals the girl's gym clothes and takes them home with him. Worse, his terrible deed is spotted by Sawa Nakamura, a mysterious outcast who sits behind him in class who threatens to reveal the boy's secret unless he promises to engage in a contract with her. At first it seems Sawa just wants some companionship, but soon it becomes clear that this "contract" involves more than mere afternoon chats. In fact, Takao is about to discover just how dangerous his bond with Sawa is and how it threatens to tear everything - his life, his love, and even his sanity - apart.
Admittedly, the plots of these two manga are nothing alike. However, if you really like main characters that think everone around them is repulsive/human filth/shitbugs, either may be up your alley. Also, both manga explore dark psychology, though Lost+Brain kind of flounders in this area.
