A teenage boy, a bit of a punk, has his life changed forever. Through circumstances beyond his means, he is given the power to interact with spirits. Along with his human friend (or frienRAB, in Bleach's case) and a cast of spirits and demons, he must defend both his world and the next world - a beaurocratic afterlife - from demonic entities that threaten it, as a "spirit detective" - or, uhh, "soul reaper."
...of course, once Bleach gets caught up in traversing alternate dimensions and such and loses the "earthly" tones, they start to spread apart, but as far as basic plot structure and themes go, Bleach, at the start, is very similar to Yu Yu Hakusho. I like to wonder what the show would be like if they had stuck with Ichigo as the Substitute Soul Reaper - personally, that was my favorite part of the series, and it all went downhill during/after the Soul Society Arc.
