Khudaiberdieva/Bazin made their debut at the senior Russian test skates, where Bazin fell on a twizzle in the free dance. They made their competitive debut at the first stage of the domestic Russian Cup series, the qualifying competition series to the 2021 Russian Figure Skating Championships, in Syzran in September. They placed first in the rhythm dance and second in the free dance to narrowly win the gold medal ahead of Morozov/Bagin. At their next event, the third stage held in Sochi, the team placed second in both the rhythm dance and the free dance to take second overall behind reigning national bronze medalists Zahorski/Guerreiro.
