Made in Heaven is a 1-volume manga by Ami Sakurai, published in 2007. It is licensed in North America by Tokyopop (who released it in two parts) and in Australia and New Zealand by Madman Entertainment.
The manga follows the story of a young man named Kazemichi who is given prosthetics after a horrendous accident almost takes his life. These prosthetics give him a new lease on life but also extract a terrible price: his heart becomes unstable and remains in danger of failing any time. Faced with this predicament, Kazemichi suddenly meets a young woman name Juri, whose love gives him the peace he needs in his soul, as well as the courage to face the fate that comes closer every second.
