We study the topological charge in $N_f=2$ QCD at finite temperature using Mobius domain-wall fermions with reweighting to ovelap fermions. The susceptibility $\chi_t$ of the topological charge is studied in the high temperature phase with varying quark mass. Last year, we reported on a strong suppression of the susceptibility, observed below a certain value of the quark mass on a fixed spatial volume. We extend this study by changing the volume to both smaller and larger direction. The relation with the restoration of $U_A(1)$ is discussed.
