Bleach is an ongoing manga series authored by mangaka Tite Kubo. Since its debut in 2001, Bleach has been adapted into an anime series, two OVAs, two anime films, a rock musical, and numerous video games. Compilation volumes of the manga have sold over 39 million copies in Japan. Bleach follows the lives of Ichigo Kurosaki, who is a high school student with the ability to see ghosts, and a shinigami (Soul Reaper or, literally, "death god") named Rukia Kuchiki, who crosses paths with Ichigo while hunting an evil spirit known as a hollow. Rukia is wounded during the ensuing confrontation with the spirit and is left with no choice but to transfer her powers into Ichigo. Thus the adventures of Ichigo and Rukia begin. Together they search for hollows and perform soul burials on wayward souls, cleansing the spirits and sending them to Soul Society. The early parts of the story focus mainly on the characters and their pasts, rather than the actual occupation of the shinigami. As events unfold, the story begins to delve deeper into the world of these gods of death on the "other side" called Soul Society.
