This book was originally only available in Japanese. The URL is listed in the text of the Japanese version, and you can access the English version from there.
Thank you to those who purchased the Japanese version in order to read the English version.
However, with the release of the English version #2 as an e-book, I have received many requests to release #1 as an e-book. I understand that some of you are from overseas and could not order it through mail order due to circumstances.
So, for a limited time only, I have made the ebook available for purchase on this page. The reason for the limited time is that some people still order the Japanese version of #1 in order to read the English version.
Sales period: January 10, 2022 - January 17, 2022
Thanks to all who have read it.
