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...
Not until we get revenge on 
the ones who made us suffer!
Nicht, bevor ich mich an jenen gerächt habe,
die uns solchen Qualen ausgesetzt haben!
No hasta vengarme
de los que nos hicieron sufrir.
Não até termos vingança
de quem nos fez sofrer!
