The series follows Ichigo Kurosaki after he obtains the powers of a Soul Reaper (or, as it's called in Japanese, a Shinigami). He is basically like what we would call the Grim Reaper. His new powers allow him to protect humans from evil spirits as well as guiding souls into the after life. It's a pretty action-packed series.
Bleach is still ongoing and has 51 volumes in English so far! Here at the library you'll find them shelved with the other manga under the letter "K".
