Rangiku ran quickly along the main corridor towards the woman's block of rooms. It was a little frustrating to be running back there at the beginning of the night instead of already heading out, but there was nothing that could be done to help it. She was armed at least, but her katana would be too valuable to leave behind on the mission tonight.
She passed the turn off to the men's block and continued, finally coming to the corridor which turned off to the female block, learned through so many days of being shuffled around by nurses during the day and explorations at night.
