Enrolled in a certain elementary school is an unpleasant 11-year-old boy with a highly cynical outlook on society. Believing that the world lacks individuality, he wants nothing more than to be unique and remembered. The boy seemingly gets the chance to leave his name in history when he becomes the first to be diagnosed with a new incurable disease that is estimated to kill him by the age of 12.

Just as he is rejoicing about his newfound individuality, he meets a cheerful, prodigious girl who has the same disease—and is nearing her 12th birthday. As the boy realizes that he won't be the first to die from the disease and therefore won't be remembered, he forms a twisted plan: kill the girl before her illness does.

tl;dr: A very unique manga centered around a boy obsessed with having individuality.

From the duo that brought you Medaka Box comes yet another very unique work. This one is centered around individuality and the lack thereof.

Spoilers below.

The premise was very unique; a disease in which you can't see individuality. A boy who is thought to be the only person in the world with this disease rejoices, as he finally gets the chance to be seen as special- until another girl shows up with the same disease. And so the boy decides the most reasonable thing to do is not console her, but to kill her off before she dies of said disease. The bloodbath commences. I really enjoyed this manga, it provides surprisingly great commentary on what it means to be an individual; that you should embrace your characteristics regardless ...

god what do i have to say about this manga. my ex best friend got me into it and, ironically enough, its about a narcissistic child whos jealous of another child who happens to be just like him (which also seems to be the reason he stopped being my friend!)
anyways its a great story, if not a bit pretentious with its explanation of morals and individuality sometimes. the art, especially the gore scenes, are incredibly striking and the author has an amazing grasp on how to portray emotion via expression. through all of the characters and plot it brings up some really interesting points on ...
