Why does Kuriyama always say "How unpleasant!"? Kuriyama often says the phrase "How unpleasant!" (不愉快です！, Fuyukai Desu!)



Did they explain this in the light novel, or is this just a typical catch phrase to make her cute?
There isn't any deep meaning to Kuriyama's fuyukai desu / "How unpleasant!" in the light novel. It's just a thing she says frequently - a catchphrase.
