There are so many good books on Amazon Japan that it becomes very difficult to make a choice.

I didn't have enough time to see all the pages, but I entered the keyword "描き方" hoping to find the drawing tutorial most representative of those I'm looking for.

Below you will find the books I have included in my Amazon's wishlist.

I did a quick check and normally, they should not have been uploaded before, but in case they would be available on the internet or already proposed here, it would reduce the list and help me greatly to make a choice among them .

I didn't have time to update the Excel list, but I took the opportunity to add KUs to my list to download them once I subscribed to Amazon Kindle Unlimited.

If you know of any other interesting kindle that has not been proposed yet, I'm interested.

Yes it has already been proposted. Please, type the keyword into google and add "Yande.re" and you'll find the exact page where it was shared. If you still have problem, I'll check it for you. It was uploaded by the generous Kitsutsuki.
