Alexis Deux is the Margrave now in charge of Fantasia Union and Lord of Jalucia. He was the son of Sylvester Deux, the late archduke of the Fantasia Union. An idealist and romanticist, he was to marry Marrine Kreische until a Chaos crashed the wedding and killed both of their fathers. While he is deeply in love with Marrine and wishes to marry her, the disaster at their wedding and the political bickering had made it all but impossible to reach out to her.
Alexis is a handsome young man. He wears bright and light-colored outfits reflect his cheerful and earnest personality and contrast the stern and coldly pragmatic black-wearing Marrine.
Alexis is always humble and effacing even when surrounded by his nominal inferiors as the head of the Union. He is a romantic at heart, something his beloved Marrine laments.
When younger, he freely taught orphaned children how to sing and earned their trust such that they ended up singing with him not for the money or food he offered but since they genuinely enjoyed his company. This was one of several things that earned him Marrine's affections.
