A mysterious phantom student is stalking Kazuya's school, and Kiriha says that there's no such thing as ghosts. That leaves only one explanation: another amasogi.
I have the student roster memorized, 
and there's no other Nago in it.
Ich sollte alle Namen der Schüler kennen.
Aber an sie erinnere ich mich nicht.
Je me souviens de tous les élèves,
mais son nom ne me dit rien.
Eu sei o nome de todos os alunos, 
 mas não há nenhuma Nago.
Я помню список всех учеников,
но Наго там не было.
