Odysseus eu Britannia
Title: First Prince of the Holy Britannian Empire
Odysseus is the Crown Prince and technically first in line for the throne, though his actual capabilities don't really match that position. His younger siblings—especially his brother Schneizel—significantly outshine him in most respects, which creates an awkward dynamic within the imperial family.
He's engaged to Tianzi, the Empress of the Chinese Federation, though the marriage is purely political. Schneizel orchestrated the whole thing as a strategy to peacefully bring the Federation under Britannian control. It's the kind of move that shows why Schneizel's often seen as the real power player in the family, even if Odysseus technically has the higher rank.
