Following Yashiro's attempt to kill him, Satoru wakes up in the year 2003 after spending fifteen years in a coma. His body continued to grow and his mother cared for him daily. However, he has lost his memories of past events. Satoru is visited by Kenya and Hiromi, as well as Kayo, who has become Hiromi's wife and mother to their baby. Some of Satoru's memories begin to return due to his friends' visits. Later, he meets a leukemia patient named Kumi, who is about to undergo surgery, as well as Yashiro himself, who changed his name to Nishizono and became a politician. Two days before Kumi's surgery, Yashiro takes Satoru to the rooftop, where he confirms Yashiro's suspicions that he has regained his memories.
