Ryousuke Akiba has the Eternal Sabbath gene. Capable of bestowing unnaturally long life and immunity to all diseases, it seems a miniature fountain of youth. However, unintended side effects of the gene include incredible mental powers that can almost totally control the mind of almost any human. Only one surviving member of the government research project knows the truth of the matter and is hunting the recipient of the ES gene to correct the wrongs of science gone awry. Yet even if Akiba has no bad intentions, another problem is brewing: he may not be the only one.
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?
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). If you are also a fan of Death Note and all this "genius anti-hero" stuff, you will enjoy Lost+Brain even more.
- Lelouch and Shu are teenagers who have great powers bestowed upon them;
- C.C. and Inori are mysterious and seductive girls;
- Kallen and Ayase are fierce and competent ace pilots;
- Similar genres (Drama, Sci-Fi, Tragedy);
- Post-apocaliptic and futuristic settings;
- Hecka mechas;
Both series have nearly identical storylines and themes such as rebellion, discrimination, supernatural powers, friendship, betrayal and Japan being a subjugated nation, needless to say that Code Geass is far more well-written and executed than Guilty Crown and the manga adaptation of the latter has an alternate ending in which a certain pink-haired girl survives.
