Convexo was a Horror that possessed the body of the Count Albar Juste (アルバール・ジャステ伯, Arubāru Jasute-haku), the rival of the Lord Rolando.


After the only man who fought evenly with Juste mysteriously became much more powerful than him, Juste became jealous and was obsessed to improve his skills further. His obsession and growing envy soon gave birth to Convexo who possessed Albar Juste in exchange for greater combat skills. Because of the rivals' transformation into Horrors, their competition took a horrifying turn which prompted Isabelle to seal borh of them.


Early History[]

It was said that Juste has never been defeated in a joust, and the only one to give Juste a draw was his rival, the Lord Rolando. The tales of their knighthood were admired by many, and everyone knew that they fought and gave their love to Juste's young wife, Isabelle. But the untold part of the story was far darker; in order to become stronger than Juste, Rolando turned into a Horror. Juste subsequently turned into one to match Rolando's new strength. Both Horrors retained their hosts' personality and rivalry, as result they competed to see who consumed more humans. The two of them attacked nearby villages and drank the blood of the young girls there until they were discovered by Juste's wife. Upon finding out, Isabelle, secretly a Makai Alchemist, sealed Rolando in the castle walls, and used a seal on herself and her husband to seal him no one could ever find them.

Carved Seal of Flames[]

Isabelle's seal would later be broken years later when a young couple accidentally stumbles into the hidden basement. After being freed, Juste kidnaps Fana, a girl who was a surrogate for Isabelle. Juste is eventually reunited with the Lord Rolando, before transforming into Aboradura and Convexo respectively. They were about to fight when Germán Luís and Alfonso San Valiante showed up. As Germán fights Aboradura, Convexo runs away with Alfonso in pursuit. In an attempt to kill Alfonso, Convexo releases Fana in midair to fall to her death, but he is slain by Alfonso while Fana is caught by her lover Mauro.


In life, Albar Juste was a revered knight whose abilities were unmatched by other knights save for one. Albar was also proficient in both joust and swordsmanship, and would retain his skills following his transformation into the Horror Convexo.
