Also, there are various anomalies in flavour-changing neutral current decays $b->sll$. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two $B$ mesons in the event offer high precision measurements of semileptonic $B$ decays. This talk presents recent Belle II results related to lepton flavor universality tests based on $B$ decays. In addition, a search for the lepton number violating decay in tau decay is presented.
