Supersymmetric U(NC) gauge theory with NF massive hypermultiplets in the fundamental representation is given by the brane configuration made of NC fractional Dp-branes stuck at the Z2 orbifold singularity on NF separated D(p+4)-branes. We show that non-Abelian walls in this theory are realized as kinky fractional Dp-branes interpolating between D(p+4)-branes. Wall solutions and their duality between NC and NF-NC imply extensions of the s-rule and the Hanany-Witten effect in brane dynamics. We also find that the reconnection of fractional D-branes occurs in this system. Diverse phenomena in non-Abelian walls found in field theory can be understood very easily by this brane configuration.
