Tite Kubo

Goodbye Parakeet, Good Night My Sister
Immediately after checking into the Kurosaki Clinic with a mysterious scar on his back, the muscle-bound Chad goes AWOL. Accompanying Chad is a talking parakeet imbued with the soul of a young boy named Yūichi. It doesn't take newbie Soul Reaper Ichigo Kurosaki long to surmise that a Hollow must be involved. By far the strongest spirit he's faced to date, Ichigo is about to discover that not every soul is bound for the Soul Society, especially if it's tainted with innocent blood.
