Yuri Briar

Yuri works in the secret police (SSS), has a keen intellect, a good observer and master of interrogations (with passions), staunch and hardy, good at shooting and hand-to-hand combat. He doesn’t know how to drink alcohol correctly and becomes completely uncontrollable. He tries everything for his sister, he loves only her. Hates Yor's husband (his sister) - Loid Forger. Looking for a Twilight spy.

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 and diplomat at the foreign ministry.

Yuri is a handsome, slender young man in his twenties with a very small cowlick on top of his straight black hair with uneven bangs. Like his sister, he has red eyes.

When at work, Yuri wears the SSS's standard uniform. Outside of his job, he wears a light brown trench coat over his black suit and dark blue tie, along with black gloves and shoes. When going outside for undercover missions, Yuri wears a bomber jacket, cap, and black pants.

Yuri has a sister complex, and even at an early age, he 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. Just the thought of Yor hating him or in despair brings him great distress. When Yuri was young, he hated himself for not being able to help her as she provided for them, which is why he began studying everything as much as he could so that he could be of help. Due to his smarts, he eventually landed a job at the foreign ministry and, shortly after, the Secret Police, which gave him the power to protect his sister.

When on the job, Yuri is shown to have a very appealing demeanor, even when extracting suspects for information. Yuri truly believes he is protecting his country, though he mostly does it for Yor's benefit, not wanting traitors and scumbags breathing the same air as her. Just as he is passionate for his sister, Yuri is very patriotic, as, when discussing "Twilight," he swiftly drops his cheery façade and becomes colder, irritable, and quick-tempered. Yuri also appears to value his family, almost immediately resorting 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.
