Even that night, one room of the apartment was shrouded in a dreary bustle.
In the room, the sound of silly laughter and chewing sweets, a cute voice like rolling a bell echoes.
While looking at the scene with a sigh, the original residents have somehow tasted a happy mood.
Ryuichi Ohata, who has been avoiding interaction with people since childhood, is somewhat attracted to his best friend, Serizawa Maki Soro, who supported him.Thanks to Kanon Nohara, the director of the Occult Research Group, who is a strange person but can not be bothered, he has regained his normal life.
On such a regular night, Ryuichi goes shopping at a convenience store and sees a strange scene in the park.
It is a girl who flutters the hem of a white dress and jumps like dancing.
It was as if the girl had no weight, not a single dust, ...... it was as if the body was floating.
"......I'm sorry, I'm sorry, I'm sorry, I'm sorry, I'm sorry, I'm sorry, I'm sorry, I'm sorry."
As if to disappear, the girl disappeared from my sight and disappeared. Really, as if it disappeared ......
"This is, after all...... Re, a spirit image?」
From this day on, a mysterious, but somewhat nostalgic summer begins around Ryuichi.
