how about...hmm...."If you use the Death Note to hereby help or cause the death of the best detective in the world *cough L cough* then you shall hereby live to meet a horrible, painfilled, blood-covered death xp "

or "If you use the Death Note to hereby help or cause the death of hagane's two other favorite characters *cough* mello and matt *cough* then you will be mobbed to death by fangirls."

or how about this? "If a person named Light Yagami uses this Death Note he will be bit by a rabid fangirl and only live to see himself biting stupid teru mikami"

there will be no exceptions to these rules.

sorry, i'm kind of hating light at the moment.
