Abstract	In the recent years, several measurements of B-decays with flavor changing neutral currents, i.e. $b \to s$ transitions hint at deviations from the Standard Model (SM) predictions. In addition there are discrepancies with the SM predictions in $b \to c τ ν$ decays. The Belle II experiment is a substantial upgrade of the Belle detector and operates at the SuperKEKB energy-asymmetric $e^{+} e^{-}$ collider. The present status of measurements at Belle II related to these so called B anomalies will be presented, including a novel search for the $B \to K ν \bar{ν}$ , $b \to s$ transition.
