After a plane crash leaves Light and L stranded in the middle of the ocean hundreds of miles away from civilization, the two must work together to survive. Light has no idea what he's doing, having never prepared for a situation like this. L is an experienced survivor thanks to his tragic backstory(TM). They battle against rising sexual tension, and Ryuk is here to watch the show.

In a world where the Death Note turns people into animals, with doves being the default, Light finds himself mistaken for the Kami known as Hachiman within a week, attracting the attention of L. Turning people into doves isn't a crime, so L is persuing him out of curiosity. Eventually, the two meet, initiating a game of metaphorical chess, a little romance, and there's a house cat.
