Bleach is a Japanese manga that is published in Weekly Shounen Jump magazine. Written by Tite Kubo, it has been ongoing since August 2001.
Bleach began as a story about a boy who could see spirits named Ichigo Kurosaki, who met a female Shinigami named Kuchiki Rukia who gave him the powers of the Shinigami in their first encounter so he could protect his family from a spiritual being called a Hollow. Since then, the story has expanded far beyond this basic original premise.
"Beyond the Pages" discusses the various concepts existing in the story in a blog format, as well as gives weekly reviews of each Bleach chapter.
