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!
and that's when it happened.
und dann geschah es.
Fue entonces cuando sucedió.
y fue entonces cuando sucedió.
C’est là que l’incident se déroula.
ed è proprio là che è successo quel fatto.
e foi quando tudo aconteceu.
