Yuri Briar is Yor Forger's younger brother and a twenty-year-old man who works in the State Security Service. He keeps his job at the SSS a secret from his sister and instead pretends to be a normal civil servant at the foreign ministry.

Yuri has a sister complex, and even at an early age, would be doing everything he could to get Yor to praise him with affection. Though this could be due to his mother dying at a very early stage in his life, causing him to get very attached to Yor as a mother figure. When on the job, Yuri is shown to have a very appealing demeanor, calmly extracting information from the people he interrogates. He is very patriotic as, when discussing "Twilight," he swiftly drops his calm façade and becomes colder and irritable, easily losing his patience. He also appears to value his family, as he almost immediately resorts to violence when he learns of a suspect's excuse for his affair. However, idiosyncratically, Yuri loses all his intelligence with his sister, completely believing Yor's excuses of "forgetting" to tell him about her marriage with Loid for a year. While capturing Franklin Perkin, Franklin poses the question about who the true disgrace is after Yuri states that he "saw no reason for Franklin's family to witness his disgrace." Yuri responds by stating how he would never "cause his sister pain," implying that his sister complex overrides his morals.

Yuri is a handsome young man in his twenties with a very small cowlick on top of his straight black hair with uneven bangs. He also has red eyes.

When at work, Yuri wears the SSS's standard uniform. When leaving work, he wears a coat over his black suit and tie, along with black gloves.

The State Security Service is an organization in Ostania established to maintain domestic order. Their primary objective includes hunting down spies and surveilling the public. Some tactics they use include violence, wiretapping, intimidation, and torture. Due to that, they are widely feared by the public who call them the Secret Police.

Intelligence: Yuri is extremely smart, able to work as a diplomat at a very early age. Interrogation: Yuri is said to be very talented for his age, allowing his boss to let Yuri tag in for a senior officer for interrogation.

Loid forger: yuri and Loid have a very complicated relationship, as Yuri is jealous of Loid for being his sister's husband without being told, so he tends to act rudely towards him, even having a one-sided competition with him over Yor's affection.

After both of their parents died at an early age, Yor was the one who raised Yuri during his childhood despite living in poverty. Because of this, he has developed a sister complex and will do anything to keep Yor safe, to the point of suspecting her husband of being an enemy spy. In addition, Yuri is very possessive of his sister, always wanting to spend time with her at every opportunity and getting irritated when someone else is around, usually Loid and Anya.

He is unaware of Yor's secret job as an assassin and also hides his job as a Secret Police officer from her.
