In a world where the powerful Britannian Empire has conquered Japan, now known as Area 11, tensions are high between the occupiers and the resistant Japanese people.
Lelouch Lamperouge, a Britannian student living in Area 11, unexpectedly gains a mysterious power called Geass, granted to him by a strange girl named C.C.
This power gives him the ability to command absolute obedience, and Lelouch, fueled by a desire for revenge against Britannia, takes on the identity of Zero.
As Zero, he leads a rebellion against the Empire, aiming to overthrow their rule and fight for a better future. The story follows Lelouch's dangerous path as he balances his dual life and wages war against a formidable enemy, navigating complex political and personal conflicts.
