Yuri is a school guardian who walked by Rose and Dimitri when they come back from the chapel. Dimitri asks him when he laid new wards and Yuri answers that he did so a few days ago. He was one of the guardians who fought with Rose as a 'Strigoi' in her field experience, along with another guardian, Jean, and Dimitri. He fought alongside Rose and Christian Ozera when the Strigoi were attacking the academy. He was one of the fifty guardians that went on a mission to rescue the Moroi and dhampirs that were kidnapped by the Strigoi. He was later killed by a Strigoi during the mission.
