This is lisited for those of you who want to order RK books at local book stores or online stores. A good online bookstore is Sasuga book store, (http://www.sasugabooks.com) I will list all prices in Yen and give an approximate, conversion for stores varies. I get my books at Asayhiya bookstores so I know they usually need titles and publishing companies. But online stores I think They take ISBNs.
