Welcome to Demon School! Iruma-kun Devilish Tales : Kalego’s Story

Long before he earned his reputation as one of the most intimidating instructors at Babyls, Kalego Naberius was just another student navigating the treacherous halls of the demon academy. However, his school days are far from ordinary. A mysterious, shadowy figure has begun targeting unruly students, eliminating them one by one, and for reasons Kalego cannot fathom, his classmates have become convinced that he is the culprit behind the attacks. Worse still, some of his peers see this as the perfect opportunity to retaliate against him for past disciplinary beatings, leaving him unfairly targeted by both the rumors and the resentful student body. Refusing to sit idly by while his name is dragged through the mud, Kalego takes matters into his own hands. Teaming up with his classmate Balam, he launches a personal investigation to unmask the true perpetrator and clear his name. What begins as a straightforward search for answers quickly escalates into something far more dangerous. As the two students dig deeper into the mystery, they find themselves drawn into a tense, high-stakes game of cat and mouse against an elusive enemy—a deadly pursuit that will test their resolve in ways only the demon world could demand.
