I am offering 25 Hath per book to the first person who can PM me a site that sells the below books. It does not have to ship internationally, I can use a deputy service. If you are looking for these books on Toranoana, make sure that the book is in stock before you notify me with a claim. Some of these books are listed because they were once sold there, but have actually been out of stock for years.
