Which character do you dislike so much that you sigh when they start talking?
Like, maybe I'm overreacting, but everytime certain characters come onto my screen I sigh and skip what they're saying (unless we're in a class trail or something). Like, I audibly just go "ugh" when they come up or when I'm forced to talk to them. For me it's Toko and Kazuichi (I don't like how their obsessive stalker-y behaviour is treated in the games)
