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!
Why wouldn't I want to be 
friends with a cute girl?

¿Por qué no querría hacer

di una ragazza carina?
Por que eu não iria querer 
ser amigo de uma garota linda?
