Bleach Volume 21

As the Soul Reapers are being healed, Byakuya confesses to Rukia that he adopted her as the dying wish of her sister, his wife Hisana, and apologizes for being unable to act on her behalf because of his promise to his family to uphold the law from that point on. As Ichigo and his friends return to the human world, Rukia decides to remain in the Soul Society. As the fall semester begins, Ichigo meets a new student named Shinji Hirako, who reveals himself to be a Visard, a Soul Reaper who has obtained Hollow powers. With his powers gone, Uryū is attacked by a Hollow and is rescued by his father, Ryūken Ishida who decides to train him to recover his lost powers. Kon, who is in Ichigo's body, is attacked by the hollow Grand Fisher who was transformed into an Arrancar, a humanized Hollow with Soul Reaper-like powers. Grand Fisher attacks Kon, believing that he is really attacking Ichigo, before Ichigo's father Isshin Kurosaki arrives to the Modsoul's defense. As Grand Fisher draws his zanpakutō to enter a stronger form, Isshin reveals himself as a former Soul reaper as he easily kills Grand Fisher in a single attack.
