Bleach, Volume 16

Ever since he was little, Ichigo Kurosaki has been able to see the spirits of the dead, so when a teenage girl materializes through his bedroom wall, this should be no call for alarm. Rukia Kuchiki is a shinigami, a member of the mysterious Soul Society that is charged with capturing rogue ghosts, and is hot on the trail of an evil spirit. But in the ensuing confrontation, Ichigo absorbs Rukia's powers, giving him the ability to not only see the undead, but to fight them as well. Now this 15-year-old high school student begins a brand new vocation: hyperkinetic, all-purpose ghost-busting. With enough attitude to make a grown ghost blush, Ichigo and crew are taking on the after-life one ghoulie at time.
