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.
His home's home would be... 
Akihabara, in other words.
Man könnte also sagen,
dass dieser Ort Akiba ist.
El hogar de su hogar sería... Akihabara.
Pour nous,
ce lieu serait Akiba.
Perciò, la casa di casa sua sarebbe...
Akihabara, immagino.
Ou seja... É Akihabara.
Так сказать, дом для дома. 
Проще говоря, Акиба.
