Unconventional superconductivity induced by the magnetic moments in a conventional spin-singlet $s$-wave superconductor is theoretically studied. By choosing the spin directions of these moments, one can design spinless pairing states appearing within the $s$-wave superconducting energy gap. It is found that the helix spins produce a ${p}_{x}+{p}_{y}$-wave state while the skyrmion crystal configuration a ${p}_{x}+i{p}_{y}$-wave-like state. Nodes in the energy gap and the zero-energy flat band of Majorana edge states exist in the former case, while the chiral Majorana channels along edges of the sample and the zero-energy Majorana bound state at the core of the vortex appear in the latter case.
