For the Aoi SR card, what does the story link actually even do? From what I can tell it delays when Aoi starts spawning for half of your debut training (very bad) and then bumps hint levels she gives from 1 to 3? Is that really it, or what am I missing?

I was surprised Gametora seems to have no information on this sort of thing, even if you look at the JP page the best you get is a very vague statement that the rewards for a few events are better in URA Finals. I'm getting exactly what it says in game, so do you get worse stuff outside of URA Finals? Why can't I find what the difference is anywhere?
