After the QCD phase transition, a QCD axion string is attached by $N$ domain walls. We would like to elucidate the fate of massless fermions on a global string after domain walls attached not only in the axion model but also in general models having string-wall composites. We investigate the Dirac equation under various string-wall composite backgrounds both in the axion(-like) models and in the ${\\cal N}=2$ supersymmetry inspired Abelian-Higgs models.
