In "Demon Slayer: Kimetsu no Yaiba," characters like Sanemi Shinazugawa and Kyojuro Rengoku are not explicitly compared in terms of IQ. However, their intelligence can be assessed based on their combat strategies, decision-making in critical situations, and general demeanor.
Sanemi, as the Wind Hashira, is known for his fierce personality and tactical combat skills. He often demonstrates quick thinking in battle, although he can be hot-headed.
Kyojuro Rengoku, the Flame Hashira, is portrayed as both intelligent and emotionally intelligent, with a strong sense of justice and compassion. He shows strategic thinking during fights and is very perceptive about the emotions of others.
Ultimately, while both characters are intelligent in their own ways, comparing their IQ is more subjective, as the series focuses more on their skills, personalities, and development rather than quantifiable intelligence.
