Bleach (tv-series, 2004)

The show revolves around Ichigo Kurosaki, a good-hearted 15-year-old high school student who carries the undesired ability to see spirits. Others in his family (two sisters and his father) carry this ability to some extent as well. One evening, he encounters Rukia Kuchiki; a Shinigami, or Death God. It is her job to usher lost spirits to Soul Society, and to also eliminate those which cross over from the Hollow World.
