Abstract
We consider the time-dependent thermal pure quantum state method and introduce the efficient scheme to evaluate the change in physical quantities induce by the time-dependent perturbations, which has been proposed in our previous paper [H. Taguchi et al., Phys. Rev. B 105, 125137 (2022)]. Here, we treat the Kitaev model to consider the Majorana-mediated spin transport, as an example. We demonstrate how efficient our scheme is to evaluate spin oscillations induced by the magnetic field pulse.

Report
In the present manuscript the authors demonstrated their scheme of the time-dependent thermal pure quantum state method, which had been proposed in their previous paper published in Phys. Rev. B, applying for the Majorana-mediated spin transport of the Kitaev model. They successfully indicated that their scheme is better than the conventional one (12). Thus the present referee thinks that the result is suitable for publication. However, the final sentence of the section 4 is still anbiguous for the conclusion. The authors should clearly write which point is improved in comparison with the conventional method. Then the manuscript whould be much more interesting. If the space is not enough, they should reduce the explanation of the method, which had already been published.
Requested changes
1- The authors should write the conclusion more clearly.

(in reply to Report 1 by Toru Sakai on 2022-10-01)We would like to thank the referee for the careful reading of our manuscript. Following the referee's suggestion, we have modified the final sentence of the section 4. We believe that our revised manuscript is more suitable for publication.
