they are a little tongue in cheek, as some view 'The Prince' as satire, I could have equally put in 'Mein Kampf' by Adolf Hitler.

I have all these books, I dont' know if Gackt has read 'confessions' (re: his own book titled 'confessions) I have heard that Mishima is more respected in the West as an author than in Japan these days, Mishima sadly, is better known for his spectacular public suicide than his writing.
