Another way is to focus on their relationship in different settings. Put them in a non - mafia related situation, like a school project or a community event. See how their dynamic changes. Tsuna might be more confident in a normal setting, and Reborn might have to adjust his teaching methods. This would show different aspects of their characters and how they adapt to each other.
With Reborn, you can develop his past. Maybe write a story where we learn more about his training and how he became the world - class hitman. This could add more depth to his character and also show how his past experiences influence his relationship with Tsuna. For example, if he had a difficult master - apprentice relationship in the past, it could make his bond with Tsuna even more special.
In KHR Tsuna x Hibari fanfiction, the settings can play a huge role. For example, if it's set in the school environment of Namimori, their interactions would be shaped by the school rules and the presence of other characters. Some fanfictions might explore how their relationship evolves when they face a common enemy, like the Vongola enemies. This can bring out different sides of their personalities and how they support each other in tough situations.
One idea could be a time - travel plot where Tsuna is sent back in time and has to rely on Reborn's teachings from the start again, but with the knowledge he already has. This would lead to some really different interactions and a chance to change certain events in a more strategic way.
The theme of friendship - turned - more - than - friendship is also quite common in KHR Tsuna x Hibari fanfiction. They start as schoolmates or comrades in the Vongola family battles. As they spend more time together, feelings may develop that go beyond simple friendship. And of course, the theme of redemption can be there too. If one of them makes a mistake or has a dark past, the other can be a source of support and redemption.
Often, they focus on the unique bond between Tsuna and Chrome. It can be a deep friendship or something more romantic. The stories usually incorporate elements from the original work, like the mafia world setting and their special powers.
For Knuckles, you could explore his relationship with his tribe more deeply. Maybe in the fanfiction, he discovers some ancient scrolls left by his ancestors that give him new powers or knowledge. This could change his interactions with Rouge and Sonic. As for Rouge, you could develop her character by showing more of her backstory, like how she became interested in jewels and espionage in the first place.
For Gay Sabastion, you could explore his backstory more. Maybe he had a difficult childhood that made him the person he is today. This could add depth to his character and his relationship with Ciel.
For Mallow, her character could be developed further by exploring her family background more deeply. Maybe there are secrets in her family related to a certain type of Pokemon. In the context of Pokemon Sun, the main character could help her uncover these secrets, which would make her more confident and also add more depth to her character.
For 2D, you could explore his insecurities more deeply. Maybe he's insecure about his voice compared to Ace's. So, he starts taking vocal lessons from Ace in the fanfiction. This would not only develop his character but also show his determination to grow as an artist.
To develop Miketsukami's character further, we could explore his past more deeply. Maybe there are some hidden traumas or experiences that have shaped his loyalty towards Ririchiyo. For Ririchiyo, we can show her growing into a more confident leader, using her relationship with Miketsukami as a source of strength.
