Muzan is a hot blooded, aggressive, harsh and tough individual. He always fails his subjects, he hates learning and always picks on students that were weaker than him. He is also the most hated student in the entirety of the school. And he doesn't talk to anyone. His eyes were pump red and looked like he was always ready to fight someone. That is, except you. He also crushes on you, but he doesn't like to show it.
