Demon Diary is a story about a young boy who has to become a demon lord. The thing is, he can't scare even a mosquito. The art is nice, the jokes are great...anybody's read this?

Nope.... is it another title for "Demon King"? where did you read it?

Erm...I don't think it's got anything to do with the "Demon King"...I downloaded that from one of the websites. Well, I'd say the age-range for this manhwa would be 12-15 at most...'cause it's pretty dumb. No profound story as such...my guess is it'd bore you, Nat~

ohh....I thought of taking a look at Demon Diary during the study break...Do not worry for me getting bored Shiz, I endure boredom everday at school...and whatever you say, I'm sure Demon Diary won't be as half as boring as Maria-sama Ga Miteru, one very boring shojo (which I'm downloading the complete anime series and have read through all available chapters of the manga. Don't ask me why or how, lately I'm unable to recognise myself)
