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!
All I did was reflect that 
impure magic of yours.
Ich habe nur deine
schmutzige Magie reflektiert.
No hice más que reflejar tu magia indecente.
No hice más que reflejar tu magia indecente.
Je n’ai fait que renvoyer
ta magie indécente !
Mi sono limitata a riflettere la tua magia impura!
Tudo que eu fiz foi refletir
 a sua magia sem vergonha.
