Mullin visits the Pandemonium Library along with Azazel and runs into the sleepy bookworm, Dantalion, as well as the ancient demon, Moloch, who always tends to talk in a loud voice. Later, Belphegor​ wants to come up with an excuse to talk to Azazel, so she starts making brownies with Beelzebub.
I remembered that I'm making 
these for Azazel-sama,
تذكّرت أنني أعدّ هذا لعزازل-ساما
Als mir einfiel, dass ich
das für Herrn Azazel mache,
Recordé que los hago
para el señor Azazel
He recordado que los hago
para el señor Azazel
Mi sono ricordata che li sto preparando per Azazel,
Quando lembrei que estou
preparando isso para o Azazel-sama,
Я вспомнила, что готовлю
пирожное для господина Азазеля,
