Background story
Katerina Valkova, mostly known as Kate, is a Russian blader who joined the Bladebreakers invited by Mr. Dickenson. Her bit beast is a giant reindeer with ice powers called Drangifer, which was inherited by Kate from her father, and her beyblade is light blue with some details in turquoise and brown.
Kate is heir of a noble Russian family. Her father was an important military and her mother a famous Bolshoi ballerina. They had very traditional habits and also were very happy together. It was Kate's father who encouraged her to start beyblading, and the girl was really very good in the sport. She fell completely in love with beyblade, especially after she started battling with Drangifer.
Unfortunatelly one day Kate's parents died because their house tragically caught fire. Kate got destroyed inside. Some years later she decided to begin a new life and used the money she had to travel alone through Europe, going to places that she used to go with her parents, meeting new bladers and trying to develop her fighting style to be a champion and honor her family. One day Kate was in Berlin taking some coffee when a guy named Robert started talking to her. She got very happy to know that he also was a blader. During the next days they kept meeting and Robert introduced Kate to some friends: Johnny, Oliver, Enrique and Martin, all of them also very good in beyblade and winners of several regional championships. In some months Kate and the guys were already good friends, but, even training together, they were not a beyblade team since everyone preferred fighting alone.
Robert and Kate were getting very close and then they started dating. They used to argue sometimes however they had sincere feelings about their relationship. So he invited her and the other guys to stay in his castle with him during the vacations and everybody accepted. Kate was finally happy again with her new friends. But she was not expecting that some months later she would be visited by Mr. Dickenson in the castle and then everything would change.
