Odysseus eu Britannia  

, オデュッセウス・ウ・ブリタニア

The First Prince of the Holy Britannian Empire is named Odysseus eu Britannia. Despite being the Crown Prince and heir apparent, his achievements are not as impressive as those of his younger siblings, particularly his brother Schneizel who holds the title of Second Prince. Furthermore, Odysseus is betrothed to Tianzi, a much younger Empress from the Chinese Federation in an arranged marriage orchestrated by Schneizel with the aim of acquiring their territory peacefully.
