Hiiro no Marionetta

After the woman he loves, Erika, dies of an illness, Jeanie sees no reason to go on living. Once an artist who painted beautiful blue skies, he has lost the desire to paint as well. Then a strange girl named Coppelia enters his life. Jeanie wonders if she is a shinigami who has come to guide him to Erika in the afterlife, or a more sinister marionette with her own reasons for seeking his life.
