I have already published Japanesn version of this blog around the end of last year, and finally finished the translation of them.
Expecting to publish this from Amazon Kindle around the end of May 2021.
Some topics in the last 4 Japanese books won't be interesting in this international version, so I picked the topics which may be interesting and conbined to one book.
Since I am not a native English speaker I had help from my highschool friend A.Jayne to sound more natural.

If you are interested in the original Japanese version, also available in Amazon Kindle from the link below.
