Spy x Family is a smash-hit anime series inspired by author Tatsuya Endo's manga of the same name, taking place in a Cold War-inspired world of political intrigue, stealthy spies and much more. Westalis and Ostania are on the brink of war, and in the middle of all this is the quirky but beloved Forger family, which has its fair share of secrets.

This family truly came to life when the Westalis spy Loid Forger proposed to the Thorn Princess assassin, Yor Briar, and Yor soon became a devoted foster mother to the adorable telepath Anya. Yor is one of the best parts of Spy x Family, including her charming and sweet personality, and her personality can be best described with her MBTI type.

Yor Briar's MBTI Personality Type: ISFJ, The Defender

Yor surprised face

Yor's personality type, the ISFJ Defender, ranks among the most common MBTI types, which is good news for any society. Defenders are humble, compassionate workers who always put others first, even if they are not terribly sociable. They will do all kinds of thankless work to keep a society, school or city running for the benefit of all. ISFJs are almost like the pillars of a society, including Spy x Family's fictional Ostania.

Defenders are known for their strong sense of loyalty and commitment, both out of duty and personal interest. These generous people will work hard to support true friends, family members and even strangers in need, meaning they are also reliable and diligent in all they do. A Defender is likely to remember and care about the personal details of everyone around them, from anniversaries to food allergies; this also makes them ideal healthcare workers, such as nurses.

ISFJ Defenders also believe there is always more to give, more work to be done to make others happy and safe, and they push themselves time and again to do their work even better. Defenders must take care to not burn themselves out with their selflessness and borderline perfectionism, though. While practical and helpful, ISFJs tend to forget to look after their own well-being, and will pay for it later.

Defenders have a contradictory nature about them, being people-oriented while also being introverted and sometimes shy or meek. This means they are simply humble workers who allow their efforts to speak for themselves, caring for other people without expecting much in return. This sets them apart from the charismatic and attention-grabbing ENFJ Protagonist type, which likes to stand on a pedestal and inspire people while fighting to defend them. By contrast, ISFJs are happy to get the job done and leave the scene without anyone even noticing they are gone. A Defender might even feel selfish or guilty if anyone praises them too much.

Yor Forger as a Defender In Spy x Family

Yor happy

So far in the Spy x Family anime, nearly every aspect of Yor Forger's speech, actions and career speak of her warm and caring ISFJ personality type. She humbly works hard at Berlint city hall as a cover for her true job as the Thorn Princess; selfless, routine work like that is ideal for a handful of MBTI types, including Defenders who like to support society from the inside without asking for much in return. In her family life, meanwhle, Yor has always been a model big sister for her brother Yuri, who looks up to her as a pillar. Yor took great pleasure in tutoring, cooking for and financially supporting Yuri, and any ISFJ would find that immensely rewarding.

In her new family life with Loid and Anya, Yor keeps up her Defender ways as the ideal wife and mother. She cares only for Loid's and Anya's happiness and believes in parenting Anya with a gentle hand, as opposed to the stern and often impatient Loid. Yor rarely plans anything ahead of time, but anytime Anya needs her help, Yor knows just what to do and will leap right into action to help -- including fighting off thugs in the Berlint streets.

Finally, Yor is deeply flattered and pleasantly surprised anytime Anya or Loid praises her, such as when they talked her up during Anya's Eden Academy interviews. A humble ISFJ will often forget to look after themselves, so a Defender like Yor will feel overwhelmed with joy when loved ones like Loid and Anya return the favor. Yor totally lost sight of what a wonderful Defender she was until her husband and daughter reminded her. That's the Defender way.
