Anime/manga Japanese transcripts

I highly recommend listening to anime and then cross-checking with the transcripts to see if you heard it right. You can also use rikai-chan (Firefox) or rikai-kun (Chrome) to check the readings of the kanji easily.

Found this for the Death Note manga:

Here's another site with both Japanese and English transcripts for animes (like Code Geass!):
