Immediately after being admitted to the Kurusaki Clinic with a mysterious scar on his back, the aged Chad disappears without being discharged. Along with Chad is a talking parrot, who has the soul of a young boy named Yuichi. It doesn't take long for the inexperienced Soul Reaper Ichigo Kurosaki to realize that someone called a Hollow is involved in the case, which is by far the most powerful spirit he has ever faced. At the same time, Ichigo will discover that some souls are not destined for the Society of Souls, especially those that have been stained with innocent blood.
