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!
She's so cute, but scary at the same time.
Sie ist süß und doch
erschreckend wie immer.
Es tan linda e intimidante al mismo tiempo.
Es tan mona e intimida 
tanto al mismo tiempo...
Elle est mignonne,
mais toujours aussi effrayante.
Come sempre, carina ma anche inquietante.
Ela é tão fofa e assustadora
ao mesmo tempo.
