because.. eugh. quick question long answer.

lets take this kanji 四, the kanji for the number 4.

The key sentence is : human legs stick out of a monsters mouth, four of them.

But you dont type 4 to get 四, you have to type よん　and since this "reading" for the kanji isnt in your book you cannot work kanji to key word.

Its 2.15am here in England so I hope that post just made sense.
