Death Note: Special One-Shot
#52 in Manga (Readables)
Bored out of his life, Shinigami Ryuk goes to the human realm once more. The year is 2017, and Ryuk believes that high school student Minoru Tanaka may have the guts to continue what Kira had started, or at least he will give some decent entertainment.
Ryuk then offers the Death Note to him and explain how it works. However, after a long thinking, Minoru proposes something else instead: he will decline the Death Note for the meantime, but if Ryuk return in two years, Minoru will grant his wish.
