The beautiful Mrinal Kulkarni is entering Kaali Ek Agnipariksha this week. She will be essaying a positive character which has some connection with Thakral (Ashutosh Rana). A source says, “Mrinal will play Sushma, a very strong and positive character and not a cameo. Rachna happens to meet Sushma and gets to know some facts which will bring a new twist in the tale. Eventually we will reveal how Sushma is related to Thakral. It will be a big blow for Thakral and then he vows to finish Rachna anyhow. Mrinal’s look will be very simple in the show and she is expected to start shooting in the next two days.” Mrinal confirmed this and says, “Yes I am doing Kaali. My character is very prominent and interesting. I have not started shooting and we are still working out various things. Therefore I will not be able divulge many details about it.” Mrinal’s character is likely to enter the show by this weekend.
