In the last phase of the fairy saga, with the climax in the castle of the Klee Kingdom, we learned of the existence of beings from the other world: the demons. One of these lower beings has already placed Black Clover’s protagonists are really in trouble. However, the current story arc has shown stronger ones.
Some of them have made a pact with the Dark Triad. Megicula, Lucifer, and another demon, whose name is still unknown in the possession of Zenon, are among the strongest in the other world of Black Clover, but Chapter 286, with The Past of Night, presented an entirely new character. Like the other demons, it only appeared in a silhouette version and looks different from the shapes we have seen so far.
Lucifugus is one of the strongest demons in black clover and its mere appearance in the real world killed all the members of the House of Faust. Although the association with the demonological ritual must limit his powers, it is strong enough to make Night tremble and make him regret what he has done. Only the intervention of tomorrow with his later death made Lucifugus disappear and return to the other world.
Now that the Dark Triad ritual has begun There is a possibility that Lucifugus will actually manage to return to the realm of the swords with physical manifestation.
