From Post-Self

█████ was Dear and Codrin's partner on Lagrange. They were a line cook prior to uploading and have since become a fine chef sys-side. They act as a moderating force on Dear.

Since they were introduced in Gallery Exhibition, a story told in second-person perspective, they are technically you, the reader. As such, their name is never mentioned aloud or in narration, and when it is written, is always written blacked out. When speaking about them during discussions of canon, their name is generally pronounced "redacted".
