The Celaeno Library in the Pleiades star cluster is home to the largest book collection in the universe. It's said that even variants of Yiu-th only handed out at events can be found there. Mahiro is dragged along for some reason as Nyarko goes there to return a book. Hasuta, a former worker at the library, does his best to show Mahiro around, but they soon encounter two evil deities who have infiltrated the library...
I see now. I guess there's a reason it's 
rumored to be an endless database.
Por supuesto... era algo que solo se 
rumoraba, como lo de la base de datos infinita.
Agora entendo por que dizem 
que é um banco de dados sem fim.
