Ikuru Yoshizumi has spent the last decade of his life suffering from a terminal illness, and his death quickly approaches. Seeking a reason to carry on in his final days, Ikuru applies for ownership of an AGH-RMS, a genetically engineered human with a short lifespan, designed to provide comfort for those who are on their last legs.

Ikuru is given Ai, an AGH-RMS who appears and functions as a girl his age. Ikuru finds his own reason for living within Ai, who is able to develop her own personality through her pure love for Ikuru. As unpreventable global conflict threatens the future of the human race, Ai and Ikuru cling to each other for safety and understanding.

This manga is a masterpiece !
I am not a native English speaker so I cannot fully describe all the feeling I have when I read every words, page and chapters.

Their relationship is doomed to end soon, but, like the other characters, they continue to find joy ...

tl;dr: A manga that tells two separate story threads that eventually collide, with one being well written and having a lot of emotional impact, and the other one being somewhat of a mess.

There was more to this series than I thought there would be, but not really for the better. The main story is about a guy, Ikuru, who's dying living with a girl, Ai, who was born in such a state that she's dying. They comfort each other and do their best to find happiness despite this. They also interact with various other characters who have stories and morals of their own. This was an incredibly well told story, with lots of really cute ...
