"So, you are saying that if Lucy found those hurt letters, she would give them to Coby any cause she enjoys watching people suffer? That's rather cruel. "

There are no hurtful letters anywhere outside of your twisted imagination! There isn't even the possibility of those twisted letters existing in Fairy Tail in any way, shape or form!

As for the decoding... do you have ANY idea how extremely complicated it is to decipher a coded text, even when you can write something down?

That "code" that Kemu used didn't have any system to it that can be analyzed and cracked, it just randomly rearranged letters to fit a new context. With no clue as to where each letter might go you basically just have a sum of letters. And with that you can make millions of different stories at the very least. How in the blazes is Lucy supposed to know which one of those millions of possibilities is the right one, even if by some miracle she had the mental capability to process all that in just her brain alone (hell the entire combined brainpower of all of mankind would still need years to process that swell of information and no, I am not exaggerating here)?

Let's give you a little cipher to do for yourself.

Gr idulhv kdyh wdlov? Gr wkhb hyhq halvw?

I'm even going to tell you how to decode it, which is a hell of a lot more than Lucy had. This is an alphabet shift. Youdecode it by shifting each letter the same number up or down the numbering of the alphabet. Meaning if the code says for example f and you think it's a 3 shift, you shift it back 3 letters f you "count down" 3 e, d, c. If you fall out below, you drop in on top. So b-5 = w (a, z, y, x, w).

Now try to figure out what the sentence above means without solely in your mind, without writing anything down.

This is the easiest code that exists on this planet and it's already a real pain to decipher without writing anything down.

But now let's take a look at the problem Lucy would be facing. Since there is no system in which the letters are re-arranged, she's basically stuck with a mass of meaningless letters of which she only knows the sums, so for example this:

a 2, e 2, h 3, i 3, l 4, m 1, o 1, p 1, r 1, s 1, t 1, u 1, y 2

Now please form a sentence out of this number of letters. Because that's what Lucy would have had to do... except with enough letters to form an entire book out of... without writing anything down...

I just used the word-count function of MS Word to gain the following numbers. A radom piece of text from a manual at 10 pt size had 288 words made out of 3420 signs (including commas, dots and stuff, but without spaces) on a single page. Now if we assume the book has around 400 pages (which seems a reasonable estimate based on the thickness of the book) we'll get to more than 1.3 million letters. Even if we assume a bigger font and only half the number of pages, that would still leave more than 600.000 signs to rearrange.

Just to give you some perspective of the sheer impossibility of the task at hand.
