It was another rainy day in the small city of Amagumo in Japan.

The rain almost never ends here. Half of the year, this city is pouring, rarely receiving any drought.

It was another rainy day in Amagumo highschool, the lights were out, shrouding the classroom in dim darkness.

Mr. Aoi Hinata went out to see the issue, leaving his students in the classroom.

Some chattered with one another, some pulled out their phones to chat their crushes or play games, some preferred to nap.
