University student Natsuna Keyaki receives a "let's meet" message from her online gaming friend Itsuki after a four-year gap in communication. When the game unexpectedly shuts down shortly after, leaving Natsuna with no way to ever contact Itsuki again, she decides to travel to Kumamoto Prefecture. With the help of a local woman, she travels to the address Itsuki had given her years ago, only to find an empty lot destroyed by the 2016 earthquakes. (Source: Wikipedia, Moeronpan, edited)
