Sis, Listen...
Mirai and Yūki are talking in the truck on the way back to their hometown, when Yuuki brings up the subject about his death. She tells him to stop talking about this nonsense, and that she and her parents would cry if he actually died. Once they arrive in their hometown, she sees Mayu, one of her friends from school. They chat, and Mayu tells her that her parents are staying in the nearby elementary school. Her dad is also being hospitalized due to an injury he sustained at work when the earthquake hit. She and Yuuki head over there, and find his best friend, Itsuki. By this time, Yūki has run off. He leads her to her parents, only to find out that her mom went back to the house to get clothing for her father. They walk outside again, and see the marronier that the two boys planted before she and Yūki went to the Odaiba Robotics Festival. Yūki is still nowhere in sight, so the two look for him.

Tokyo Magnitude 8.0
The premise of the project is the 70% possibility that a magnitude 7.0 earthquake will occur in Tokyo in the next 30 years. The anime depicts what would happen if an 8.0 earthquake took place.
The story centers on Mirai, a middle school freshman girl who goes to Tokyo’s artificial Odaiba Island for a robot exhibition with her brother Yuuki at the start of summer vacation. A powerful tremor emanates from an ocean trench, the famed Tokyo Tower and Rainbow Bridge crumble and fall, and the landscape of Tokyo changes in an instant. With the help of a motorcycle delivery woman named Mari who they meet on Odaiba, Mirai and Yuuki strive to head back to their Setagaya home in western Tokyo.
