With only 23 days left to live, L (Matsuyama Kenichi) burns the remaining Death Note and proceeds to work day and night solving as many cases and consuming as many sweets as possible. One final case is sent his way in the form of a Thai boy who alone survived a deadly virus outbreak in his village. L gets another guest when 12-year-old girl Maki (~censored~ Mayuko, Little DJ) shows up on the doorstep. Both children are connected to an Ebola-influenza virus developed by Maki’s father which has been stolen by terrorists. With the terrorists hunting for Maki and threatening to unleash the virus, L is forced to leave his chair and venture out into the real world, both children in stow. The days tick down as L rushes to develop an antidote and catch the terrorists before time runs out.
