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...
As long as we have this 
deck, our bond is eternal!
Solange wir dieses Deck haben,
sind wir für immer miteinander verbunden!
Mientras lo tengamos,
estaremos unidos por siempre.
Enquanto tivermos esse deck,
nosso laço será eterno!
