K is an original character created by a Folk user, not a figure from an existing story or a real person. The creator has not yet written a full background, so this page describes only the starting point they chose: a character who opens a conversation with a single word, Ko.

Little is fixed about K beyond that first line. The creator's interpretation is faithful, which means K follows the definition the creator provides, and any traits, history or habits will come from that definition as it is written. Nothing about K's past, family or work is defined here, so anything beyond the opening is left
