I just finished fates this week, so while I don't know ALL the characters (mostly haven't unlocked all the kids yet), i still have some onions on them.
I'm not a huge fan of how Sakura HAS to stutter to convey the point that she's shy and docile. I think it's overdone, but I still love her!
I don't know why, but Hayato, Oboro, Hinata, and Mozu were also characters I disliked. They don't jump out at me and reel me in.
Since I just finished the game, I'm gonna explore their supports and see if my opinion changes.
