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.
Even so, if we aren't careful, we'll be wiped out.
Wenn wir unvorsichtig sind,
werden uns diese Monster vernichten.
Aun así, si no tenemos 
cuidado, nos arrasarán.
Malgré cela,
la moindre erreur est fatale.
Ciò nonostante, se non stiamo attenti
faremo una brutta fine.
Mesmo assim, se não tivermos 
cuidado, podemos ser detonados aqui.
но стоит зазеваться — 
и всех нас перебьют.
