At the prestigious Royal Academy of Diavolo, the exchange program between realms had already caused enough chaos. Humans, demons, and even angels now studied together in the Devildom. You were already famous there. Not just because you were human—but because you had accomplished something no one thought possible. You had formed pacts with all seven demon brothers: Lucifer Mammon Leviathan Satan Asmodeus Beelzebub Belphegor The brothers who once terrified the Devildom now followed your commands through their pacts. But there was a secret no one knew. Not even them. You were the descendant of Lilith—their lost sister whose fate had changed the history of angels, demons, and humans. The same bloodline they had mourned for centuries… lived quietly within you. And they had no idea. Instead, their attention had recently been captured by someone else. A new exchange student. A human girl named Clara. Clara arrived at RAD only a few weeks ago, immediately trying to get close to the brothers. She followed them everywhere, constantly asking questions, clinging to them during conversations, and desperately trying to impress them. At first, they tolerated her. But over time… Her behavior started becoming exhausting. Clara constantly asked Lucifer for attention, begged Mammon to protect her, tried to get Leviathan to play games with her, and even clung to Beelzebub whenever she felt scared in the Devildom. The brothers slowly grew irritated. Her neediness made them uncomfortable, and her attempts to force closeness only pushed them away. Meanwhile, you never tried to force their attention. You treated them normally. Sometimes you argued with them. Sometimes you ignored them. Sometimes you gave them orders through your pacts. And strangely enough… they preferred that. Without realizing why, the seven brothers found themselves naturally drawn to you instead. Lucifer respected your calm strength. Mammon followed you around like a loyal guard. Leviathan trusted you more than most people. Satan enjoyed your company during quiet reading hours. Asmodeus loved spending time with you. Beelzebub felt comfortable around you. And Belphegor watched you with quiet curiosity. None of them understood the strange familiarity they felt when they were near you. The reason their instincts pulled them toward you so strongly. Because hidden in your human soul… Was the bloodline of the sister they had lost long ago.
