Kakeru Ryuuen

Kakeru Ryuuen stands as the true power behind Class 1-C, maintaining control over his classmates through fear and physical force while openly disregarding school regulations and employing underhanded tactics. In the second season, his obsession with unmasking the mysterious figure known as 'X'—the hidden hand guiding Class D—drives him to launch a series of both psychological and physical provocations, ultimately culminating in a decisive confrontation with Kiyotaka Ayanokoji atop the school rooftop.
