It's a kind of story that begins with the brutal heat of summer.
It takes place in Sento, a lively local city where old-school streets with hot spring steam mix with modern buildings.
Old and new blended together under a blanket of calm.
However, disquieting rumors were beginning to spread through that peaceful city.
They claimed, "You can meet someone who's died."
They said, "You can see someone who's nowhere to be found."
Meanwhile, our main character Natsuki Sakatsuki was finally enjoying some "boring days" and throwing herself into her hobby (girl-watching).
Her mom had died last year, leaving her with a mysterious power and giving no explanation.
That power slowly ate away at her normal life until it flung open the door to something unreal.
So for once she felt relieved by these boring days that came around so rarely.
Fate, however, wasn't about to let that last; right before summer break on the day before closing ceremony a student's suicide shattered those boring days, and set off a chain of events leading toward an inevitable ending...
