Meaningless [C]ode Episode 11

▶▶ Pod 153 - Report: 9S, subject of this unit’s support, was injured when he was caught in the upheaval caused by the appearance of the giant structure identified as the ＜Tower＞. Currently, he still needs maintenance and rest, but unit 9S refuses. He has left the Resistance Camp and is approaching the Tower. It has been discovered that access to the Tower ＜Main Unit＞ requires a structure known as the ＜Sub-unit＞ to be unlocked. This unit, in collaboration with 9S, will begin searching the Sub-unit for the passcode.
