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!
Oh, yeah. You're the one 
who made me naked, too.
Oh, ja. Du bist die,
die mich nackt gemacht hat.
Es cierto.
Es cierto.
C’est vrai, c’est toi
qui m’as déshabillé la dernière fois.
Ora che ci penso, sei stata tu quella
 che ha denudato anche me.
Ah, é. Você que me deixou
 pelado da outra vez.
