main character



Continuation of The Big O. Notes: - Originally planned as a 26-episode series, low viewership in Japan reduced production to the first 13. - Positive international reception resulted in a second season consisting of the remaining 13 episodes; co-produced by Cartoon Network, Sunrise, and Bandai Visual.
Probably, if you enjoy action, mecha and mystery, especially stories with amnesia, dystopian, noir.
Reception is positive but mixed: 73/100 on AniList, with 57% of 1.7K ratings at 8/10 or higher. It's the #13 highest-rated anime of 2003.
Once people start, they tend to finish: only 1.7% of viewers drop it.
