In this work, we construct a radiative neutrino mass model that allows for the production of boosted dark matter in the present universe through semi-annihilation. A Dirac fermion serves as the dark matter candidate, which semi-annihilates into an anti-dark matter particle and a neutrino. Taking into account the relevant experimental and theoretical constraints, we find that the boosted dark matter can be probed by DARWIN if its mass lies in the range of 20--50 MeV and the semi-annihilation proceeds through a resonance with a tuning of $\mathcal{O}(0.1)\%$. Furthermore, the monochromatic neutrino produced simultaneously with the boosted dark matter can also be detected at Hyper-Kamiokande and DUNE in part of the allowed parameter space.
