Actually that is the one issue about Fi that really weighs her down. She very AI like in attitude but in a rather anime sort of way which means that she’s rather subdued in her quirks, often times employing the blank stare or the quizzical head tilt; which is rather unfortunate given that most westerners are not familiar with this type of behavior nor are observant enough to notice anything at all.
And in fact one could make that case for the overall game as it employs a greater number of anime cliches than most Zelda games have done in the past. Game starts in a highschool, Groose and co are the Libby and co, Ghrigham feels like a misplaced Sailor Moon villain at times, and other things I won’t go into at this time. It’s actually kinda bizarre given pretty much everything about Malo was in TP.
As for the gossip stones the one you’re probably referring to is this game’s Super Guide, it’ll show you footage of things you’ll either need to do or have already done. It’s actually nice as it’ll let you know if you’ve seen everything of interest in an area or not but I haven’t found the need to use it for anything beyond figuring out what it does. There is a second type but the game will fill you in as it becomes relevant.
The key business among other things is just Nintendo being gimmicky with its new gimmick.
