Shiroe and his friends have come to the Depths of Palm to reach the Sacrifice Clan's gold.  The underground labyrinth is filled with powerful monsters that wear them down in a war of attrition.  Meanwhile, Akihabara, Akatsuki hears about the "Teachings".  She's very interested to know that by completing a high level raid, she can greatly improve the level of her techniques.
We don't even know how big the zone is,
Wir kannten weder den Zonengrundriss
noch wussten wir, wie viel noch übrig war.
No sabemos qué tan grande es la zona,
et on était même incapables
de se représenter la zone dans sa totalité.
Non sappiamo né quanto sia grande il posto,
Nem sabemos o tamanho total disso,
Мы не то что зачистить зону —
даже составить её полный план не могли.
