Millie

Millie is a female civil servant who works in the same office as Yor Forger.

She is part of Yor’s circle of coworkers, often appearing in everyday workplace scenes.

She has a lighthearted, carefree personality that sometimes makes her seem insensitive.

Because of this, she often blurts out tactless remarks to Yor without realizing how they might sound.

Whenever Millie goes too far or speaks out of line, she is frequently scolded and reined in by Sharon.

This dynamic creates a small comedic trio in the workplace: Yor as the quiet straight man, Millie as the talkative instigator, and Sharon as the one who keeps things in check.

In terms of backstory, Millie lost her father in the war against Westalis.

This detail adds a quiet layer of tragedy to her otherwise bright and casual demeanor, linking her life to the broader East–West conflict that shapes the world of Spy × Family.

Millie’s main role is to flesh out Yor Forger’s civilian life and social environment.

Her casual gossip, teasing, and misunderstanding of Yor’s private life help highlight Yor’s double role as both an assassin and an ordinary office worker.

She often provides comic relief by making offhand comments about relationships or marriage, accidentally putting pressure on Yor.

These moments underscore how carefully Yor has to balance her cover as a normal woman with her secret life.

Through Millie’s background—especially the loss of her father in the war—the story subtly illustrates how the prolonged conflict between Ostania and Westalis has affected ordinary citizens.

Even though she appears mainly in light scenes, that detail hints at deeper emotional stakes beneath her cheerful surface.

Millie’s full name is Millie Myers.

In English-language discussions of Spy × Family, she is usually referred to simply as Millie.
