Middle school student Mirai Onozawa is dissatisfied with her family circumstances and, in a moment of frustration, wishes to tear everything apart. Unfortunately, these destructive thoughts seem to come true in the form of a magnitude 8.0 earthquake just a few moments later. When summer vacation begins, Mirai reluctantly takes her younger brother Yuuki to Odaiba, where a robot exhibition that he wanted to go to is being held. However, while they are in the exhibition center, the fury of a major earthquake shakes the Kanto region; helpless, both kids witness the devastating power of this natural disaster as it brings the city to its knees. In its aftermath, they stumble upon Mari Kusakabe, a motorcyclist and single mother who decides to help the young siblings. Aiming to return to their homes and reunite with their families, the group sets off on a long and hard journey through the decimated city. The premise of the project is the 70% or higher possibility that a magnitude 7.0 earthquake will occur in Tokyo in the next 30 years. The anime will depict what would happen if an 8.0 earthquake took place. The story will center on Mirai, a middle school freshman girl who goes to Tokyo’s artificial Odaiba Island for a robot exhibition with her brother Yutaka at the start of summer vacation.
