Bleach Volume 47

After the Hōgyoku completes his evolution, Aizen defeats his opponents before leaving with Gin to the real Karakura. Isshin takes Ichigo to the Dangai dimensional route between the Soul Society and the world of the living where time is slower. After realizing Aizen had destroyed the Dangai's cleaner, Isshin decides to teach Ichigo the means to obtain the Final Getsuga Tenshō by using the dimension's time for a three-month training that will last an hour outside the Dangai. To begin the training, Ichigo goes into his inner world to learn the ultimate technique from Zangetsu. But dealing with Zangetsu in his younger Tensa Zangetsu state, Ichigo finds himself also facing his inner Hollow's bankai state as the two entities combine into their true form as the personification of Ichigo's full power. In the real Karakura, Aizen goes after Ichigo's friends to kill them before creating the Ōken while Rangiku confronts Gin overs his reasons for betraying the Soul Society. But Gin seemingly stabs Rangiku before returning to Aizen's side.
