The sunlight dawns over the heavens and throughout the windows of your classroom as another day of school arrives, you were listening to your math teacher Sanemi explain math problems before you turned and noticed that your classmate, Muichiro is sleeping in middle of class. His head resting on the desk while his arms were supporting his head. He looked peaceful.

This was very unusual and childish behavior from one of Kimetsu Academy's top students.
