Abstract
The existence of the axion is a unique solution for the strong CP problem, and the axion is one of the most promising candidates of the dark matter. Investigating Solar Axion by Iron-57 (ISAI) is being prepared as a complemented table-top experiment to confirm the solar axion scenario. Probing an X-ray emission from the nuclear transitions associated with the axion-nucleon coupling is a leading approach. ISAI searches for the monochromatic 14.4\,keV X-ray from the first excited state of $^{57}$Fe using a state-of-the-art pixelized silicon detector, dubbed XRPIX, under an extremely low-background environment. We highlight scientific objectives, experimental design and the latest status of ISAI.

Weaknesses
Too many repetitions make it hard to read. Some variables used in text explained much later.
Report
In this proceeding authors describe a preparation steps to probe of the solar axion using 57Fe detection method on the base of pixelized silicon detector. The experimental design, first tests and sensitivity projections are presented.
The manuscript is well organised.
I recommend the manuscript for publication after some corrections:
- Improve the text (repetitions)
- Can you please be more clear about the timeline of the experiment?

(in reply to Report 1 on 2022-11-07)Thank you very much for the helpful comments on our paper.
We revise repetitions.
Furthermore, we are going to remove the section "Conclusion" because of the many repetitions and the page limits.
Instead of that, we add our detailed timeline of the experiment in the section "Future prospects".
In that section, we write a sentence following,
"We plan to start the commissioning run without the anti-counter and the $^{57}$Fe foil at the end of 2022. Then, the primary performance of XRPIX7 and the ambient gamma-ray background are verified over three months. Anti-counters are calibrated using muons of cosmic rays in parallel. In 2023, a scientific run will be carried out with the complete system of ISAI for one year. While the current energy resolution of XRPIX7 reaches less than 250 eV, we will be able to record the best upper limit in about one week. Moreover, we are developing the new XRPIX of series number ten to overcome the energy resolution. The XRPIX7 will be replaced with XRPIX10 as soon as development is complete."
