Mawaru Penguindrum

Both are about having notebooks that could change fate - one controls death while the other controls fate but comes with a price instantly. Deathnote has a darker tone and heavier messages/wordy whereas penguindrum has a deep tone but makes up for it using colorful artwork as well as whacky music and mahou shoujo theme anime.
