Deriglazova was left extremely frustrated by her Olympic experience and resolved to train harder under the new direction of Stefano Cerioni, former coach of the Italian foil teams. During the 2012–13 season she won her first World Cup title at Budapest, followed by three other victories in Saint-Petersbourg, Tauberbischofsheim and Seoul. Her ambitions for the 2013 European Championships in Zagreb were however cut short in the first round of the individual event by World No.88 Anastasiya Moskovska. In the team event, Russia were defeated by France in the semi-finals, then by Hungary in the match for the bronze medal, and came away with no medal. Deriglazova bounced back by taking the gold medal at the 2013 Summer Universiade after defeating teammate Larisa Korobeynikova in the final. At the World Championships in Budapest Deriglazova made her way to the semi-finals, where she was defeated 15–11 by Arianna Errigo and took the bronze medal. In the team event, Russia were defeated by France in the semi-finals, but prevailed over South Korea to earn the bronze medal. Deriglazova finished the season World No.2 behind Errigo.
