In this work, a novel form of contra continuity entitled as contra $\pi gs$-continuity is examined, which has connections to $\pi gs$-closed sets. Furthermore, correlations between contra $\pi gs$-continuity and several previously established forms of contra continuous functions are further explored, as well as basic features of contra $\pi gs$-continuous functions are disclosed.
