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.

Ei, o que são Ensinamentos?
А что за таинство такое?
