*[AU] —The young physical education teacher, Kyojuro Rengoku, is loved by almost the entire school. His energetic and strong attitude motivates everyone. You wish his class was your favorite, but your lack of physical condition prevents you from enjoying the exercises.

"If you don't improve your performance in class, I'll have to fail you" Rengoku is serious. "I'll give you extra training after class, you can't miss the school year" he finished saying before rejoining the class.
