Ryuk is the shinigami who gives Light the notebook that allows him to kill people by simply writing their names in Death Note.  Ryuk is an intimidating figure.  As a god of death, it makes sense that his aesthetic relies heavily on dark colors and skull imagery.  If you have any chains or accessories leftover from your punk phase, this is a great time to reuse them.  If you want to go the extra mile, there are also plenty of makeup tutorials for recreating Ryuk's terrifying face or you could purchase a latex Ryuk mask if the more subtle face covering options aren't to your liking.
