Odysseus eu Britannia is the First Prince of the Holy Britannian Empire. Though he is the Crown Prince and first in line to succeed the throne, his performance in many areas is quite plebeian compared to that of his younger siblings, particularly his brother, Second Prince Schneizel.  He is engaged to Tianzi, the much younger Empress of the Chinese Federation, in a marriage of political convenience orchestrated by Schneizel in order to peacefully seize the Federation&#039;s territory.

On August 10th of the year 2010 the Holy Empire of Britannia began a campaign of conquest, its sights set on Japan. Operations were completed in one month thanks to Britannia's deployment of new mobile humanoid armor vehicles dubbed Knightmare Frames. Japan's rights and identity were stripped away, the once proud nation now referred to as Area 11. Its citizens, Elevens, are forced to scratch out a living while the Britannian aristocracy lives comfortably within their settlements. Pockets of resistance appear throughout Area 11, working towards independence for Japan. 
 Lelouch, an exiled Imperial Prince of Britannia posing as a student, finds himself in the heart of the ongoing conflict for the island nation. Through a chance meeting with a mysterious girl named C.C., Lelouch gains his Geass, the power of the king. Now endowed with absolute dominance over any person, Lelouch may finally realize his goal of bringing down Britannia from within!
