Global Garden (GLOBAL GARDEN - アインシュタイン睡夢奇譚 Gurōbaru Gāden - Ainshutain Suimu Kitan?) is a manga by Saki Hiwatari, who is best known as the creator of Please Save My Earth.

The series was published in Hakusensha's Hana to Yume which comes out bi-weekly in Japan. The series is completed at 8 volumes.


The story begins in Princeton, New Jersey, 1954, with Albert Einstein. Einstein is living in regret of his discovery of mass-energy equivalence (E = mc²), believing it led to the construction of the atomic bomb.

He meets two children, Hikaru and Haruhi, who can see the past and future in their dreams. They tell him that ever since the atomic bombing of Hiroshima and Nagasaki, Yggdrasil, the tree of life, is dying.

However they discover that in the future there is a girl with special powers who saves the tree. Einstein then gives them drugs which slow their aging so they can meet this girl. He dies later the same day; April 18, 1955. He then becomes the story's disembodied narrator, following around the young boy Robin.

In Tokyo, 2005, Hikaru and Robin finally find the girl, Ruika. Ruika is pretending to be her young brother Masato, who died in an airplane crash, to keep her mother from grieving.
