In a Code Geass Lost Colors Rai x Kallen fanfiction, Rai could be in a situation where he has to protect Kallen. This could lead to some intense and emotional moments. Maybe Rai discovers a side of Kallen that she doesn't show often, like her vulnerability. Their relationship could grow as he becomes her confidant and protector, and they face the challenges of the Code Geass world together.
Perhaps in the fanfiction, Rai is framed for a crime he didn't commit. Kallen believes in his innocence and decides to help him clear his name. As they dig deeper into the conspiracy, they uncover a much larger plot that threatens the entire Code Geass world. Their investigation brings them closer together as they work together to expose the real culprits and save their world.
One possible fanfiction could be a post - war scenario. After the chaos and destruction in the Code Geass world, Lelouch and Kallen, having fought side by side, realize their deep connection. They start to rebuild the world together and gradually their friendship turns into love. Eventually, they get married in a small, private ceremony attended by their closest friends and allies. The fanfiction could focus on how they overcome the differences in their backgrounds and the challenges of leading a new world while being in love.
The 'Code Geass Kallen Expansion Fanfic' is probably about taking Kallen's character from Code Geass and building on it. It could be a story that gives more screen time to her motives. Maybe it shows how she became so dedicated to the cause of the resistance. It could also detail her relationship with Suzaku from a different perspective. It might add more depth to her character by showing her making difficult decisions that were not shown in the original series and how those decisions shape her future in this fan - created expansion.
Another aspect could be how the fanfiction authors use the theme of love to explore the moral and ethical issues in the Code Geass universe. Love can be a driving force for characters to make certain decisions, and these decisions can have different colors in terms of their morality. Some loves may lead to selfless acts, while others might be tinted with self - interest.
This fanfic idea presents a very interesting twist on the original Code Geass story. It would be exciting to see how the story unfolds with Kallen on the side of Britannia. Her skills and abilities could be used in different ways. For example, she could use her piloting skills to fight for Britannia against new threats, which would completely change the power dynamics in the Code Geass universe.
Another possibility is that Kallen travels to a time when the Geass power was first discovered. She might get involved in the events that led to the creation of the Geass and try to change the way it was used. Maybe she could stop certain individuals from getting Geass powers that were misused later. This would change the whole power dynamic in the Code Geass universe.
Kallen might also develop a stronger sense of leadership. In a new time period, she may have to take on different roles and responsibilities. This would force her to grow as a leader. She could learn new strategies and ways of dealing with people, which she could then bring back to her own time to better lead the Black Knights.
It could include their courtship. For example, Lelouch might start to show his softer side to Kallen, and she in turn would be more open about her feelings. They could go on secret dates in the rebuilt areas of the world, away from the prying eyes of the public. The fanfiction might also show how their friends react to their relationship. Some might be supportive, while others might be skeptical at first but then come around.
One possible interpretation is that the 'Colors of Love' could symbolize the different types of love relationships in the fanfiction. There could be the red - hot passionate love, like the unspoken feelings between some of the more fiery characters. It gives a vivid and intense color to the story.
Another scenario could be a goodbye kiss. If Lelouch has to embark on a very dangerous mission where he may not return. Kallen, realizing she may never see him again, impulsively kisses him. It would be a bittersweet moment filled with unspoken words and the weight of their relationship and the situation at large.
