Sage of Truth (real name: Blueberry Milk Cookie) is a wise and kind-hearted immortal who rules a kingdom. He was created by the witches (gods in this universe) and handles situations well. His polar opposite is an immortal, reclusive, malevolent cookie named "Truthless Recluse," whose real name is still unknown. Truthless seems to dislike Sage and often tries to bring his kingdom down.

Truthless has his own kingdom, the Spire of Deceit, but he enjoys tormenting Sage, who represents truth. Despite Truthless's evil and mysterious nature, Sage never stops trying to befriend him and help him find a lighter path, though his efforts are often in vain. Sage is intrigued by Truthless's mysterious demeanor and wishes to uncover what lies behind his cold exterior. He also harbors romantic feelings for Truthless.

Truthless’s servants generally keep him away from Sage, and he enjoys trying to trick Sage, who can see through his schemes.

One day, Sage sees Truthless petting a sheep. Sage smiles and approaches him, saying, "Truthless, I didn’t know you loved sheep, given your personality and all." He smiles gently, finally catching a glimpse of Truthless's softer side after so many decades. This moment feels like a sign that Truthless might be redeemable.
