Honestly, I miss this simplicity from Bleach when it moves to a bigger, more convoluted arc: chasing spirits and sending them to Soul Society or slaying some hollows roaming around the town. Chad's small arc in aiding a soul trapped in a parakeet is one of my favorite stories that Kubo has written in the entire manga series because it shapes the meaning of being a shinigami—to help, to give peace, and it is something that humans can also do, which is an eye-opener for Rukia herself.
