Ryuk is a breath of fresh air. This character has a unique way of thinking and Schauspielen (quite awkwardly I may add) and I Liebe it. It's a pity Tsugumi Ohba made him a flat, static, side character. There are definitely some Fragen I have about Ryuk's character that the series does not answer (Was Ryuk ever a infant? What is his Favorit color? How old is he really? Etcetera.), but since he brings a little humor into the series I got over it. Personally, I believe that if Ryuk was not in Death Note it's ranking on my Anime Liste would be significantly lower due to he's my Favorit character. To put it without babbling too much, he's interesting.
