Tokyo Magnitude 8.0

A massive earthquake strikes while Mirai Onozawa and her brother visit Odaiba, Tokyo.

With the help of Mari, a motorcycle courier, Mirai searches for Yuki inside a collapsing building.

Mirai, Yuki and Mari decide to travel to their homes together but quickly realize how dangerous the journey will be.

The trio gathers supplies and, after wandering from Mari, Mirai and Yuki find serious trouble.

Mari, Yuki and Mirai find refuge at a school but fail to find rest as aftershocks continue and depression sets in.

The trio reach Mari's workplace but Mirai and Yuki are shocked when Mari passes out and someone enters the building carrying a baseball bat.

Yuki is fascinated by rescue robots at work and meets a new friend with the same interest.

Mirai is concerned for Yuki after he collapses and is taken to the hospital.

Mari finds her home destroyed and believes her mother and daughter are dead.

Mirai meets a friend who tells her where her parents are and Yuki makes a stunning announcement to his sister.

Mirai and Yuki reach their home and their parents; a month after the earthquake, Mari visits and returns Mirai's cell phone and Yuki's backpack.
