Theo Cornaro (テオ・コルネーロ) is the male protagonist of the series. A wandering knight who obtained a Crest from a Chaos Core. He comes from Sistina, a village ravaged by Chaos and oppressed by their Lord, Viscount Phederico Rossini. After rescuing Siluca from soldiers and telling her his goal to free his hometown, he becomes contracted to her and together they fight to stop the feuding lords and end the Chaos era.


Theo is a man of average height and weight and has dark green hair. He wears a long dark green and gold coat that compliments his hair and that covers his left arm with a white and gold armor and has a sword sticking to his waist and wears a greyish pant with brown boots that goes right below his knee and wears a right glove on his right arm. He also wears a black choker.


Theo rarely loses his cool, regardless of the situation. The only times when this was subverted were when Siluca suddenly summoned a monster to help level up his Crest, when he comes face-to-face with Rossini and when Villar dies. Even then, he doesn't go over-the-top with his emotions. He's kind and respectful to everyone, valuing his morals and ideals because of these he so popular amongst other Lord. He protects Siluca from soldiers without even knowing her and is always the good king to the villagers. He vaguely notices that Siluca has feelings for him but initially shrugged them off as his imagination. Later he brings it up when they're alone, which results in a kiss and a love confession. He always chooses the path that will result in less casualties but will fight if he has to. This mindset doesn't sit well with Milza.


Prior to the series, Theo went into exile because he was unable to forgive the villagers for his father's death and due to this reason he hated the Rossini family. His father created a secret grain barn for the people of their town. But when the Rossinis found out, the townsfolk betrayed him and he was executed as an example.
