In search of Hanako's secrets, Nene and Kou enter the fifth Wonder, the 4 O'clock Library. It's books contain the past and future of every student their school has ever had, but some knowledge comes at a price.

Egal was andere sagen,
Digan lo que digan,
es una piedra lunar.

para mí es una piedra lunar.
Peu importe ce qu’on dira,
c’est une pierre de lune.
Não importa o que digam,
é uma pedra lunar.
