Four teenage boys are struck by lightning and live. A strange girl named Shuri comes to the boys. She tells them a parallel gate has opened and demons and monsters will enter into our world. But only if the four beasts, that now reside in each boy, don't close the gate. Now begins their trial. Can these boys close the gate without dying?

Gate had one volume published in English by ADV Manga on March 1, 2005 before the license was dropped and the publisher went defunct.
