▶▶ 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.
