After losing her parents, Shizuku Haiya was taken in and abused by her aunt, and was unable to find hope in her life. And her special ability to "see a certain future" makes her despair even to others around her.
When I decided to commit suicide, a mysterious man named Hakuto appeared.
Shizuku, who was pressed by Hakuto to "need the ability of Shizuku" and was needed by someone for the first time since her parents, used her ability to help Hakuto's plot ...? mysterious man one day.
Hakuto said, "If you send 100 souls to heaven (kill ), you can bring your parents back to life."
