Entries for different versions of Lucius.5★ - No. 8202: A demon born of chaos. Lucius is proud and quick tempered, going as far as killing some of his own demon followers when suffering from one of his violent fits of rage. On occasion he is cold towards his sister Lilith, another demon born of the same chaos, but often shows he cares when he coddles her. One night when the moon was full and red as blood in the night sky, he learned that a being feared by all demons called "the Count" had appeared out of nowhere...6★ - No. 8203: A savage demon born of chaos. When a certain being called "the Count" appeared one night before Lucius under the light of a full moon painted in scarlet, he claimed that his goal was to rule over all the demons in the world. Although many yielded to the Count's demands and swore their loyalty to him, Lucius and his sister were too proud to bend the knee. The battle that then ensued between the opposing parties destroyed a great part of the region and continued until the sky itself was tainted blood-red, leaving Lucius and Lilith with severe injuries.7★ - No. 8204: A demon and his younger sister stood amidst the destruction that resulted from their fight against the Count. Their foe had merely become a battered body at their feet, cursing their existence with what little breath he had left to spare. As blood poured out from his wounds, the roar Lucius belted out was heard until the ends of the earth. Whether he cried out to celebrate his victory, or to mourn the damage he had caused around him, not even his sister really knew.
