Seven days with the Ghost

Ayako needs her Occult Research Club to survive — that means recruiting members, which means generating interest, which means actually investigating the Seven Wonders of the Academy. Each wonder she pursues collapses under scrutiny until only the Seventh remains: get kicked by a horse and die. Out of options, she tries it. She does not die, but she does accidentally dig her own grave and find something strange inside it. Seven days of strange, funny, and unexpectedly precious events follow.
