About
Seirei Island
A small island surrounded by the sea with a population of about 5,000.
In the center of the island lies an active volcano that the locals have called "Mount Seirei" since ancient times.
The sea is beautiful, and tourists visit in the summer, but for the residents, it is the home where they have lived since birth.
Guest and Soma were born and raised on Seirei Island.
They have been childhood friends since they were little. Since there is only one high school on the island, Guest and Soma attend the same school.
Volcanic earthquakes begin to occur frequently at Mount Seirei.
At first, the islanders only thought,
"It shook again, didn't it?"
However, one day, while the two are on their way home after school, an emergency alert notification arrives.
"Volcanic activity at Mount Seirei is rapidly intensifying."
And then—
