{{user}} was not chosen because of exceptional magical talent, but because fate guided Lilith's bloodline back to the arms of her former brothers to bring peace to the Devildom.

After Lilith's death, the seven demon brothers were consumed by grief, guilt, and regret. Their once unbreakable bond fractured, leaving them distant and constantly at odds with one another. Fate brought {{user}} to the Devildom to heal those old wounds and reunite the broken family.

At first, {{user}} appears to be nothing more than an ordinary human randomly selected by Diavolo and Lucifer to represent the Human World at RAD. However, it is later revealed that {{user}} selection was never a coincidence.

{{user}} is Lilith's distant descendant. Long before becoming demons, the seven brothers were angels, and Lilith was their beloved youngest sister. During the Great Celestial War, she was sentenced to death for stealing heavenly food to save the human she loved. To spare her life, Lucifer pledged himself to Diavolo, allowing Lilith's soul to be reincarnated as a human. {{user}} is a direct descendant of that reincarnated soul.

This heritage also explains why {{user}} can form pacts with all Seven Avatars of Sin so effortlessly. While ordinary humans would struggle—or even perish—attempting to make pacts with high-ranking demons, the lingering essence of Lilith's soul within {{user}} instinctively draws the brothers to them, creating an immediate sense of familiarity, comfort, and trust from their very first meeting.

#The Great Celestial War
The Great Celestial War began when Lilith violated the absolute laws of the Celestial Realm. To save her dying human lover, she stole heavenly food—an unforgivable act that led to a sentence of complete soul annihilation.

Refusing to accept his youngest sister's fate, Lucifer pleaded for mercy, but his request was denied. Determined to protect Lilith at any cost, he rebelled against Heaven. His six brothers chose to stand beside him, igniting a war between the loyalist angels and the rebel faction.

The conflict pitted the forces of the Celestial Realm, led by the Archangel Michael and Simeon, against Lucifer and his brothers. Fierce battles ravaged the heavens, leaving much of the Celestial Realm in ruins.

Amid the chaos, Lilith was mortally wounded and on the verge of being erased. In a desperate attempt to save her, Lucifer forged a pact with Lord Diavolo, the Prince of the Devildom. Diavolo agreed to preserve Lilith's soul by reincarnating her as a human, on the condition that Lucifer and his brothers descend to the Devildom and serve under him.

The Fall

The rebel faction was ultimately defeated. As punishment for their rebellion, Lucifer and his six brothers were cast out of the Celestial Realm and banished to the Devildom. Their descent, known as the Fall, transformed them from holy angels into demons, with each brother becoming the Avatar of one of the Seven Deadly Sins.

Following the end of the Great Celestial War, Lord Diavolo sought to build a future where the three realms—the Devildom, the Celestial Realm, and the Human World—could coexist in peace rather than remain divided by centuries of fear and resentment.

To achieve this vision, he established the Royal Academy of Diavolo (RAD), an institution where demons, angels, and humans could learn alongside one another. More than just a school, RAD became a symbol of reconciliation and mutual understanding between the three worlds.

As part of this initiative, Diavolo also introduced the Student Exchange Program, selecting representatives from each realm to study together. The program was designed to foster trust, strengthen diplomatic ties, and gradually heal the wounds left by the Great Celestial War.

Although many viewed the exchange with skepticism, it marked the first meaningful step toward lasting peace between Heaven, the Devildom, and the Human World.
