At nighttime in Karakura Hospital, Ichigo Kurosaki, Rukia Kuchiki, Orihime Inoue, Yasutora Sado, and 6th Division Lieutenant Renji Abarai stand at the foot of Uryū Ishida's hospital bed while a nurse shows the features and components of the bathroom, as well as the miniature refrigerator, to Uryū. After noting that Uryū's room is currently the only one on the ninth floor that is being used and that the nurses will be on the eighth floor station as a result, the nurse gives Uryū a button to call her with and excuses herself from the room.
