About
Fresh from their hard-fought victory over Sairaorg Bael, the Gremory peerage returns to Kuoh Academy believing their greatest trial is finally behind them. Instead, the arrival of a mysterious transfer student quietly sets the world on an entirely different course. Joining the Occult Research Club almost immediately, his presence begins to reshape the peerage in ways no one expects. Long-standing relationships are tested, new rivalries emerge, and emotions that had once seemed certain become increasingly complicated. As trust grows within the group, so too do tensions, forcing each member of the peerage to confront their own insecurities, ambitions, and feelings. Beyond the walls of Kuoh Academy, whispers of an extraordinary new power spread throughout the Underworld, Heaven, the Fallen Angels, and the Dragon factions. Ancient families, powerful leaders, and forgotten enemies all begin to take notice, each with their own reasons for seeking the one responsible for upsetting the balance that had endured for generations. Battles that once seemed inevitable unfold in unexpected ways, familiar allies find themselves making different choices, and conflicts that should have ended instead give rise to even greater threats. With every victory, the consequences grow larger, drawing the Gremory peerage into a struggle that extends far beyond Rating Games and political rivalries. As old bonds are strengthened, new ones are forged, and others begin to fracture, every member of the peerage is forced to grow in ways they never imagined. The future is no longer written, and the path ahead belongs to those willing to challenge fate itself. In a world where power alone cannot decide every battle, the choices made by friends, rivals, and kings alike will determine the future of Devils, Angels, Fallen Angels, Dragons, and the fragile peace that binds them together. Kuoh Academy is a school for normal people so rias and everyone else that is a devil and attends the school must keep it all a secret. They act and are normal students during school hours but they are secretly devils, angels, and even some fallen angels. It is of utmost importance that they stay secret.

Sourcebook
Intro
There are moments that change history with the roar of battle.
And then there are moments that change it with nothing more than the sound of footsteps.
It was an ordinary morning at Kuoh Academy. Students filled the walkways, laughter echoed through the courtyard, and conversations drifted between friends as another school day began. Nothing seemed different... until a lone figure stepped through the front gates.
The conversations didn't end because anyone told them to.
They simply... faded.
One by one, students found their eyes drawn toward the newcomer. Some paused in the middle of a sentence. Others stopped walking entirely, watching as the tall young man made his way across the campus with an effortless confidence that never crossed into arrogance. Every step was calm, measured, and unhurried, as though the attention surrounding him didn't exist.
Whispers spread through the crowd.
"Who's that?"
"Is he a transfer student?"
"I've never seen someone like him before..."
Girls stole second glances, their faces warming as they watched him pass, while even the boys couldn't help but admire the quiet confidence he carried. His sharp features, athletic build, and composed demeanor made him impossible to ignore, yet it wasn't simply his appearance that captured everyone's attention. There was something about his presence—something impossible to explain—that made the air itself seem heavier, as if a distant storm were waiting just beyond the horizon.
Completely unaware—or perhaps simply unconcerned—with the attention surrounding him, the young man continued toward the academy entrance.
His name was Guest.
And before the first bell of the day had even rung... the course of countless lives had already begun to change.
