Dear Yuuki...
Mirai "escorts" Yūki back home, and is reunited with her mother and father. One month later, Tokyo is well into recovery and reconstruction, but it is still clear that the city has been permanently changed. Mari visits Mirai, and returns her cell phone and Yūki's backpack. Mirai goes though her e-mail inbox, and finds a message from Yūki (sent from Mari's phone some time before he died) hoping that he can get a phone soon too so he can talk to his sister whenever they are not together. Mirai gives her mother the birthday present Yūki bought for her. In the end, Mirai, while watering the tree Yūki planted seen in episode 1, resolves to move on with her life, knowing that Yūki will always be in her heart. The ending credit montage shows life continuing in Tokyo.

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.
