  We study $SU(N_c)$ gauge theories with Dirac fermions in representations
${\cal{R}}$ of nonzero $N$-ality, coupled to axions. These theories have an
exact discrete chiral symmetry, which has a mixed 't Hooft anomaly with general
baryon-color-flavor backgrounds, called the "BCF anomaly" in arXiv:1909.09027.
The infrared theory also has an emergent $\mathbb Z_{N_c}^{(1)}$ $1$-form
center symmetry. We show that the BCF anomaly is matched in the infrared by
axion domain walls. We argue that $\mathbb Z_{N_c}^{(1)}$ is spontaneously
broken on axion domain walls, so that nonzero $N$-ality Wilson loops obey the
perimeter law and probe quarks are deconfined on the walls. We give further
support to our conclusion by using a calculable small-circle compactification
to study the multi-scale structure of the axion domain walls and the
microscopic physics of deconfinement on their worldvolume.
