Mari lives with both her mother, and her daughter, Hina. Incidentally, Hina turned four years old on the day that the earthquake struck. When Mirai questioned her as to why was she helping her and her brother, she responded with, &quot;because I&#039;m a human&quot;. 

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&rsquo;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.
