We propose a new type of radiatively induced neutrino masses at three-loop level based on the Ma model, introducing a non-invertible symmetry in the class under a \mathbb Z2 gauging of \mathbb Z6 symmetry and adding three isospin doublet vector-like fermions L' and singlet boson S0. Under this symmetry, the Yukawa interactions directly related to the neutrino masses are not allowed at tree-level. However it is allowed at one-loop level due to L' and S0 as well as η, which is no longer invariant under this symmetry. Therefore, the symmetry is dynamically broken. Intriguingly, η plays important roles in contributing to both the radiative matrices yη and mν. After constructing our model, we show some numerical analyses to satisfy the lepton flavor violations, muon anomalous magnetic dipole moment, and a boson dark matter candidate S0 or ηR for the cases of normal hierarchy and inverted hierarchy. Then, we demonstrate allowed space for our input parameters.
