The Josephson effect of inter-layer s-wave pairing in a double layer of two chiral metals is considered. We employ the duality relation between electron-electron and electron-hole double layers to discuss the zero-energy eigenmodes at a domain wall and their coupling to the superfluid state. This is described in terms of the quasiparticle current and the supercurrent. It turns out that the degeneracy of the zero-energy eigenmodes is resolved by the coupling to the supercurrent. The duality relation between the electron-electron and electron-hole double layers leads to the same current distribution in both systems but to different zero-energy modes.
