Black Throne

Allen, who came from another world, lived in seclusion in Blackthorn City with the acumen of a spy and an unknown hidden power. He accidentally obtained a black sword "Death Knell" that could absorb dark energy and exude a strange aura. This sword has an inexplicable fit with him, but it also hides an unknown ancient secret. The mystery of his own life experience has always been lingering in his mind and cannot be solved.
