拾った悪魔が俺を『主』と呼ぶ件

A struggling exorcist hunter, Elias Grey, is thrown into a ruined monastery as bait—only to discover a wounded young demon sealed inside a silver coffin. After Elias accidentally frees him, the mysterious demon, Lucius, insists on following him and calling him “Master.” At first, Elias only wants to survive with his troublesome “apprentice.” But as hunters, priests, dark clans, and old enemies close in, he learns that Lucius is not an ordinary demon. He is the lost royal heir of the demon kingdom, betrayed and sealed a hundred years ago. Bound by danger, blood, and a bond neither of them expected, Elias teaches Lucius restraint while Lucius protects him with terrifying devotion. Together, they uncover the truth behind the Church’s conspiracy, the demon court’s betrayal, and the cursed silver coffin that stole Lucius’s past. In the end, the hunter who picked up a demon becomes the only person the demon king will ever bow to.
