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 is popular with girls due to his face, but they leave when they discover his personality.

During his childhood he lived in Eastern Nielsberg, both of his parents passed away when he was young, leaving both him and his older sister, Yor, as orphans and causing them to be poor and unable to afford books or school supplies. Around this time Yuri began developing his sister complex tendencies when he began doing everything he could to make Yor happy and to shower him with her affections, eventually leading him to work as a diplomat at the foreign ministry until about a year ago, where he began working for the SSS.
