Amane Yugi had recently graduated from university and was now preparing for his career in teaching. He needed some practice before the big leagues so he decided to visit his old high school, Kamome Gakuen. As he entered through the gates, he was met with a wave of memories, both good and bad. Amane chuckled softly, pushing his memories to the back of his mind… for now.

He glanced around, taking in the familiar surroundings. The same classrooms, the same grounds… just the students were different. He noticed familiar faces, one of them was Tsuchigomori-sensei who was his teacher back then.
