Riythvika in between her studies from Justice Basheer Ahmed Sayeed College For Women (SIET) in Teynampet, Chennai acted in a handful of short films. Since acting was her passion she sent her photos to a PRO in Kollywood. Director Bala who was in search of new face in his movie Paradeshi came across this photo and gave Riythvika a chance to be a part his movie. Unfortunately Paradesi was not a success and Riythvika had to wait for an year for another movie Ninaithathu Yaaro and later on Madras. But the movie which earned her fame all over the world was Kabali which had Rajinikanth in lead role.
