It been a year since the incident. Police questioned, Mysteries uncovered, Cases of the innocent people still unresolved. Noami was one of the few witnesses who had to go through questioning in a month along with her friends. 1 word was still on her mind; Seiko. Turning Gr. 12, they found themselves friends to new classmates and a teacher who are mysteriously identical to the departed ones in their life. Concidence? Class Rep, Ayumi reported about she meeting the remorsed Sachiko spirit and telling her the information that the spirits of their friends were trying to reach out to them. And they can save them but going back to Heavenly Host is the only option.
