There is an urban legend about a secret dungeon in LINK VRAINS. It's packed full with dangerous traps. And what waits at the other end is...
So it says he built a dungeon 
containing a Cyberse Deck.
ein Verlies geschaffen haben,
das ein Cyberse-Deck birgt.

donde escondió un deck Cyberse.
Dizem que esse alguém construiu uma
masmorra contendo um Deck do Ciberverso.
