Thanks to Aru, Yukiteru and Yuno are set up on an unexpected date at a free "wedding trial" program. But Aru's scheme goes awry when Yukiteru and Yuno arrive at Yuno's house to find not corpses, but a giant hole in the ground. And if that wasn't weird enough, Yuno has tampered with her memory and forgotten that Yukiteru ever visited her. Her memory loss couldn't have come at a worse time, as they are both tricked into committing a crime so another Diary owner can track them. With the game stakes becoming deadlier than ever, has Yukiteru sent his last text?
