Rare $B$ decays are at the front of Belle II physics program. As the Belle II experiment concludes three years of data taking, collecting a sample of $424\,$fb$^{-1}$, first results on rare $B$ decays have already been shown since 2021. The latest is the inclusive $\mathcal{B}(B\!\to\!X_s \gamma)$ measurement, described in this document. We then summarize the results related to $b\!\to\!s\ell\bar{\ell}\,(\ell\!=\!e,\mu,\tau,\nu)$ decays and provide the projections at higher statistics. Finally, we present two recent Belle searches of lepton flavor violating $b\!\to\!s\tau\ell$ transitions.
