One

Odin is a light blue Arabic numeral for "one" (1), based on the symbol for "1" with a base (𝟷), likely borrowed from the original Minesweeper game. The diagonal portion and base of the "𝟷" symbol are shifted, with the base being further to the left. Unlike almost all known algebraic beings, Odin has no arms. Sometimes Una's eyes seem to extend beyond her body, and sometimes they appear narrower and more slanted, especially when she is angry. In the episode "Alone", her imagination and stickers reveal that she has eyelashes.
