| Summary:
We present the first search for the lepton flavor-violating decay modes $B^0
rightarrow K_S^0 tau^pm ell^mp~(ell=mu, e)$ using the 711 fb$^{-1}$ and
365 fb$^{-1}$ data samples recorded by the Belle and Belle II detectors,
respectively. We use a hadronic $B$-tagging technique, and search for the
signal decay in the system recoiling against the fully reconstructed $B$ meson.
We find no evidence for $B^0 rightarrow K_S^0 tau^pm ell^mp$ decays and
set 90% confidence level upper limits on the branching fractions in the range
of $[0.8,,3.6]times10^{-5}$.
