In her apartment in Karakura Town, Orihime Inoue finishes writing a set of instructions covering laundry, garbage, and food for 10th Division Captain Tōshirō Hitsugaya and Lieutenant Rangiku Matsumoto so they do not make a mess and looks at the bracelet on her left wrist as she recalls Ulquiorra Cifer's explanation of how wearing it envelops her in a special spiritual membrane so only Arrancar can see her, which will also allow her to pass through solid objects and which she can never take off.
