This time Lupin is after 500 tons of gold bullion that used to belong to the House of Romanov, the last rulers of the Russian Empire. His only clue is a code in an old book that a cipher machine has broken down to the words "Bank of Liberty." As always, whenever Lupin's involved, the situation gets complicated. This adventure takes him through the USA and Russia, with loads of action and classic Lupin-style escapades along the way.

Life in the bustling city of Orario is never dull, especially for Bell Cranel, a naïve young man who hopes to become the greatest adventurer in the land. After a chance encounter with the lonely goddess, Hestia, his dreams become a little closer to reality. With her support, Bell embarks on a fantastic quest as he ventures deep within the city's monster-filled catacombs, known only as the "Dungeon." Death lurks around every corner in the cavernous depths of this terrifying labyrinth, and a mysterious power moves amidst the shadows. Even on the surface, survival is a hard-earned privilege. Indeed, nothing is ever certain in a world where gods and humans live and work together, especially when they often struggle to get along. One thing is for sure, though: a myriad of blunders, triumphs and friendships awaits the dauntlessly optimistic protagonist of this herculean tale. [Written by MAL Rewrite]
