Kiriko and Haruki Kiruko tells Maru how five years ago, ten years after the calamity, siblings Haruki and Kiriko Takahaya lived in an orphanage. The older sister, Kiriko, was a successful electro-kart racer while her younger younger brother Haruki hung out with the much older Robin, who was the leader of a group fighting man-eater monsters. One day during a race, Haruki saw a man-eater on the course and tried to kill it himself. However, he failed and the monster began to consume him. When Kiriko saw the beast, she crashed her kart into it. She pulled what was left of Haruki's torso from its maw and then collapsed from her injuries. Later, Haruki woke up in a hospital, but realized that he had Kiriko's body after the doctor operated on them. Months later, Haruki tried to find out what happened, but the orphanage and everyone he knew was gone. Four years later, he met Maru in Nakano. Maru still has trouble accepting this information when suddenly the ferry is attacked by a fish monster with arm-like appendages. Meanwhile in Heaven, Kuku criticizes Kona's drawing of a baby, saying they do not have faces as she has seen one herself.
