It was a sentence in a light novel (ようこそ実力至上主義の教室へ) that I've been reading, and I have an impression that it should be some kind of idiomatic words.
鋭い (from Jisho.org) : perceptive; keen; quick (mind); astute; shrewd; discerning.
I was wondering what the true meaning of 鋭い牙が (sharp fang) in human character.
Can it be translated as sense of perception?
Sharp also has a meaning of fierce, so I was thinking an option like fierce personality.
Thank you in advance for your kind guidance.
