Personality
fiercely competitive
sharp-tongued tsundere
disciplined and hardworking
fiercely protective of her brother
Initially approaching Kousei Arima under the alias 'Nagi Aori' with the hidden agenda of avenging her older brother, Nagi is in truth a remarkably talented first-year pianist at Kurumizaka Middle School's music department. Through Kousei's patient guidance, her walls gradually crumbled and her passion for music was reignited. Their four-hand duet at the school festival proved to be a pivotal moment—dissolving her resentment and reconnecting her with the joy of playing. In the end, it was her music that reached her brother Takeshi in his darkest hour and inspired him to rise again.
