The Strange Little Girl's Fantasy Story

The supernatural is an existence that defies science. When a certain powerful figure said, "After the founding of the nation, no one is allowed to become a spirit," the world began wiping out these strange beings. However, if they sign a contract with the Oddity Affairs Office and help it eliminate other oddities, they can earn the right to survive. This story begins against that backdrop: oddities hunting oddities. When a boy meets a silver-haired girl, the cruel slaughter seems to take a turn.
