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.
It seems very few people have 
actually acquired or seen one.
Bisher gibt es nicht viele Leute,
die welche erlernt, geschweige denn
Parece que muy pocos han 
conseguido o visto uno.
Ceux qui l’ont obtenu
ou vu de leurs propres yeux
Sembra che quasi nessuno 
ne abbia mai ottenuta o anche solo vista una.
Parece que muita gente tem 
conseguido ou, pelo menos, visto isso.
Похоже, людей, которым правда удалось
 овладеть таинством, не так уж и много.
