Hmm, I think this would have played better if Link had been set up previously, instead of being mentioned for the first time and then mastered by the protagonist in the same scene. Oh well, what I like about this series outweighs that one nitpick. Thanks for the translation!
Agreed; this is really something I'd have preferred have been foreshadowed earlier in the work. Like, have there be instances where they almost seem to read his mind, or act in sync unconsciously, etc.
Then the MC's epiphany during the match would be much more satisfying because it would be an "oh so THAT's what it is, I know I can do this" moment instead of a complete asspull.
