Enter! The World of the Shinigami

Ichigo Kurosaki, Uryu Ishida, Orihime Inoue, Yasutora "Chad" Sado, and Yoruichi Shihoin cross over into Soul Society using the gate. They arrive in the Rukongai, where normal spirits reside. Ichigo quickly finds himself in a battle with the gate watcher Jidanbo when he carelessly tries to enter the Seireitei, where the Soul Reapers reside. Thanks to Urahara's training, Ichigo easily defeats Jidanbo, but when Jidanbo opens the gate, Ichigo encounters the third division captain Gin Ichimaru.
