Something is wrong with history. There was a huge war that nobody can really remember, and a massive number of people are said to have died in it. Clues to this mystery arise from an unexpected source when Naoya and his brother meet a woman who went to school with the mysterious Shoko Futami...
She was just gone one day.
 No one knew where she went.
اختفت عن الجميع دون أيّ تنبيه
Ohne Vorwarnung ist sie
vor uns allen verschwunden.
Sin previo aviso,
delante de nuestras narices.
Sin previo aviso,
delante de nuestras narices.
Sans prévenir,
elle a disparu sous nos yeux.
Si è allontanata da tutti,
Ela sumiu para todos,
sem qualquer aviso.
Она бесследно исчезла,
 никого не предупредив.
