She will enter the family drama as Jhumki, a Rajasthani girl who is Roli's look-alike.
Roli's death has shocked the Bharadwaj family, but there is another surprise waiting for them in the role of Jhumki, a rustic outspoken girl.
In her new role, Avika will be seen wearing Rajasthani attire - ghaghra-choli, something that she used to wear for her role in "Balika Vadhu".
"I have mixed feelings. While on one hand I feel sad about the end of Roli's character, which was loved by the audiences very much, on the other I, am excited to be seen in a new role. I think a new role always offers an actor something new to learn and experiment with," Avika said in a statement.
"I also hope the new twist is loved by everyone," she added.
The new character will be seen from next week in the the show that comes on Colors.
