YMMV: Code Geass: Nightmare of Nunnally
- Genius Bonus: Some of Nemo's lines take on a lot more meaning if you understand what her name means in Latin.
- Les Yay: Alice adores Nunnally, and flat out tells her that she loves her in the end. This makes Nunnally change her mind regarding her father and mother's plan. There's also the canon Les Yay that Cornelia felt towards her half-sister Euphie...
- Memetic Mutation: Zero is Master Asia and can stop bullets by POSING.
- Nightmare Fuel: The first time Nemo surfaces through Nunnally's repressed anger is utterly jarring, especially in contrast to how gentle and warm she outwardly seems.
- Pandering to the Base: The author admitted in the final volume that some of the major changes to the storyline were influenced by him being a Code Geass fan. These changes including saving Euphemia and Lelouch from dying.
