A more romantic plot could be that Lelouch and Kaguya meet in a sort of in - between world. They initially clash due to their strong - willed personalities, but as they get to know each other, they start to fall in love. Lelouch might be intrigued by Kaguya's elegance and intelligence, while Kaguya could be drawn to Lelouch's determination and the mystery behind his Geass power. Their relationship could then develop as they face challenges together, both from Lelouch's world of political intrigue and Kaguya's world of high - school politics.
One idea could be a story where Lelouch uses his Geass ability in the world of Kaguya - sama to gain an advantage in the student council battles. Maybe he Geass - es a rival student to support Kaguya's schemes, leading to some really hilarious and strategic situations.
A possible plot could involve Lelouch losing his Geass powers and being captured by Cornelia. Instead of punishing him immediately, she decides to study him to find out more about the Geass. During this time, they engage in many deep conversations. Lelouch tries to convince Cornelia of the wrongdoings of Britannia's system, and Cornelia starts to question her own beliefs. This interaction could lead to a romantic relationship as they both grow and change through their exchanges.
One idea could be a story where Lelouch and Suzaku have to work together secretly to prevent a new threat to the world that neither Britannia nor the Black Knights are aware of. They have to put aside their differences and use their unique skills and knowledge to save the day.
To create a compelling interaction between Lelouch and Kaguya, first, you need to understand their personalities. Lelouch is a strategic mastermind with a hidden identity and a thirst for revenge. Kaguya is a prideful and intelligent girl who is used to getting what she wants. Have them engage in intellectual battles, like a game of chess. For instance, they could be planning a school event together and constantly trying to outwit each other in the planning process.
There are fanfictions that explore their relationship from a more emotional side. For example, a story where CC reveals her past traumas to Lelouch, and he in turn shows her a side of himself that he has never shown to anyone else. This deepens their bond in a very different way compared to the main series.
The power dynamics. When Lelouch gives someone Geass, it completely changes the balance of power. For example, if he gives it to a character who was previously powerless, like a civilian, that character suddenly has the ability to influence others in a major way. This can lead to all kinds of new plotlines and character interactions.
One interesting plotline could be Lelouch having to deal with the aftermath of his 'death' being faked. Maybe he has to secretly guide the new world order he created without revealing his true identity. Another could be his relationships with the other characters, like how he reconnects with C.C. in a new and different way.
One plot idea could be exploring Cornelia's relationship with her subordinates in a more in - depth way. Maybe she has to lead a risky mission and how she overcomes the challenges within the team. Another could be a story set in an alternate universe where Cornelia has to make different choices that change the fate of the Britannian Empire.
The themes of sacrifice and redemption are quite common. Rolo, in particular, has actions that could be seen as in need of redemption, and Lelouch's own goals often require sacrifice. Fanfics may focus on how Rolo tries to redeem himself in Lelouch's eyes or how Lelouch sacrifices for Rolo. Additionally, the theme of power and control is present. Lelouch has the Geass power, and how he uses it in relation to Rolo and their relationship can be a central theme in fanfics.
One common theme is the exploration of their complex relationship. Given their unique personalities and the circumstances in the Code Geass world, fanfics often focus on how they understand and support each other. Another theme is the idea of power and sacrifice. Since both Lelouch and CC are tied to power in different ways, many fanfics will play with the concept of what they are willing to sacrifice for each other or for their goals.
The story mainly revolves around Lelouch Lamperouge. He obtains the power of Geass, which allows him to command others to do his bidding. In the context of love, there are complex relationships. Lelouch has deep emotional bonds with various characters. For example, his relationship with C.C. is full of mystery and mutual understanding on some levels. They share a connection through the Geass power and their common goals. Also, his feelings towards his sister Nunnally play a huge role in his actions and decisions throughout the story, as he is determined to create a better world for her.
