Ai-Ren

Ikuru is a boy who doesn't have long to live. Grown up question the purpose of his life and the reason for his death, he's grown up constantly confused and lonely. Now, learning that he hasn't long to live, he requests that a special "girl" called a AGH-RMS be given to him. These people are genetically made so that they help heal and ease the mental burdens of someone who hasn't long to live. This manga is cute, sad and ultimately a story about life, death and humanity.
