This proceeding is based on [1] where we study a model in which the SM is coupled to a Hidden sector via heavy messengers. In this framework, instanton densities of the Hidden sector behave in the IR like axions coupled to the SM. We study the general properties of such emergent axions and we show that they are different from both fundamental and composite axions that have been studied so far.
