We propose a new kind of axion model derived from the Grand Unified Theory (GUT) based on $SU(5)\times U(1)_{\rm PQ}$. We demonstrate that, given a certain charge assignment and potential flavor models, the axion is naturally hadrophobic and provides a novel explanation for the required condition using isospin symmet...
