Screaming Book of Doom

The Screaming Book of Doom is a black and silver book featured in Magical Girl Team Lucky Star. Whenever the book would be opened, it would let out an earsplitting note. It appeared to be a collection of Buddhist prayers.
==Overview and Creation==
Keel took a book of Buddhist prayers and used his magic to convert it into a scare device. Whenever someone opens the book, it would let out an earsplitting scream that would eventually curse the owner.
==Quotes==
Konata: Ah, that one looks like a good one! (Konata pulls out the book and tries to read it, but an earsplitting scream scares Konata, making her scream. The book flies out of her hands, landing on the ground shut with the scream still ongoing.)
Tsukasa: What happened!?
Konata: That book; it was screaming! It scared me and flew out of my hand and shut itself, but the scream went on and on with an earsplitting note!
