The girls are running in their exercise outfits, with the boobs swaying to and fro. Arata's heart races. Everyone's having great time, and then a ghost appears in the library. Arata and the gang go to check it out, and are forcefully transported to the "Eternal Library". There they find the lost Trinity Seven!
The next thing they knew, 
the older of the twins was gone.
Nur die Ältere von beiden war fort.
Desapareció la mayor de las dos.
Desapareció la mayor de las dos.
Quand elle revint à elle,
la petite sœur était seule.
dopo l'incidente, la più grande era scomparsa.
A mais velha das gêmeas sumiu.
