This is because Mikami, following his incarceration, lost his sanity and died ten days after Light Yagami, making it appear too convenient for their deaths to have occurred in such close proximity to each other. Matsuda proposes the theory that Near, who had had the Death Note in his possession, could have possibly controlled Teru Mikami's actions the previous year. They ponder at the coincidence that they’re meeting at exactly the same place on the same day that they did a year ago. Aizawa calls up Ide and Matsuda and tells him about the drug deal bust in the YB warehouse and that they are to meet at 21:00 hours. He asks Aizawa to aid him in busting a drug deal that will take place in Japan three days from then.
He connects him to Near who is typically playing with his toys but is now eating a chocolate bar as a tribute to Mello. The new Watari, Roger Ruvie, previously the caretaker of Wammy's House, calls Shuichi Aizawa, who is now the detective superintendent of the NPA. Touta Matsuda and Hideki Ide are walking down the street and debating whether what they did was the right thing. The world has reverted to the same state it was in prior to the appearance of Kira.
It has been one year since the events from the previous chapter.
