Rika Tsukishima, a first-year high school girl, transferred from China to Tokyo, thinking she could live a normal high school life without the pressure of involution. She has the arrogant and venomous but reliable friend Chihaya Chinatsu, the cold-faced Kashiwahara Kosuke who always cares about her inadvertently, and the netizen "ユメ" who she has never met but chats with her late at night - everything is like the days when she was loved in her fantasy.
But in the dusk in Tokyo, crows squat on the head of Ksitigarbha Bodhisattva, staring at everyone passing by. The emergency room of the hospital has no windows, but someone inside saw crows looking in from the windows. In the subway car, the girl in school uniform disappeared in the blink of an eye and smiled at her again in the glass reflection.
Rika started to notice something strange:
Some people are obviously rescued successfully, but they seem to be different people - they can't hold back their urine, their personality changes drastically, they suddenly grow taller, and they start eating things they hated before.
Little did she know, it was a possessed person.
She also didn't know that it was no coincidence that she would inexplicably want to eat things she didn't like and couldn't hold back her urine during her menstrual period every month.
She didn't even know that the netizen "ユメ" who chatted with her gently might be by her side.
And the way Kosuke looked at her was like a window in winter, covered with a layer of frost - that's because there was something on the other side of the window that he didn't want her to see.
This is a story about "unfinished business after death".
What is pushed out from the rescue room may not be a living person.
And some people would rather become monsters than stay with the people they like.
Concept: Death is not the deepest darkness.
Being forgotten is.
