Mein Kampf (My Struggle) is the evil version of the Enclosed Instruction Book. It was written by none other than Adolf Hitler. It is harmful to those who read it repeatedly, as they will slowly get brainwashed into nazism. The reader's IQ will instantly drop by 21.
The book is locked away in its own cell in the Hyrule State Prison, so that no one can read it or even look at it.
Mein Kampf was written by Adolf Hitler in 1925, when he first met a Jew. Due to the Jew not conforming to him and accepting Jesus, he killed the man and wrote the book in his blood.
All later copies were wrote in red ink, but the nazis continued their torture, having that as an excuse.
