When Alice transfers to a new middle school, she hears an urban legend about a student who disappeared the previous year and is suspected to have been killed by his fellow students.
Even worse, Alice discovers that she lives next door to his former house, a supposedly haunted home now occupied by a reclusive classmate named Hana.
Hana and Alice decide to investigate this “murder case” together, but soon find their lack of detective skills may be an obstacle.
