The relationship could start with hostility. Makoto, being the protagonist, would naturally oppose Monokuma who represents the chaos and death in the killing game. But as the story progresses, they could find common ground. Maybe they both want to uncover the truth behind the game, but for different reasons. Monokuma might want to see how the truth affects the participants while Makoto wants to stop the game.
Another way to develop their relationship is through a series of challenges. For example, Monokuma sets up challenges that only Makoto can solve, and in the process, they start to understand each other better. Makoto might start to see the complex programming and rules that govern Monokuma, and Monokuma might be intrigued by Makoto's ability to think outside the box. This could lead to a grudging respect between them.
A more psychological approach could be taken. Makoto could try to psychoanalyze Monokuma. He could study Monokuma's actions and words to find patterns and motives. Monokuma, on the other hand, could play along, seeing it as an interesting experiment. As Makoto delves deeper into understanding Monokuma, their relationship could shift from one of enmity to a strange form of friendship or at least a mutual understanding.
One idea could be that Monokuma, in an unexpected turn, decides to spare Makoto from a difficult trial situation. Maybe he sees something unique in Makoto's will to survive and his positive attitude. This could lead to a strange sort of alliance where Makoto tries to understand Monokuma's motives better.
The relationship could start with Junko being intrigued by Makoto's naivete. She begins to stalk him subtly, leaving little hints that she's interested. As time passes, she becomes bolder and starts interfering in his daily life more directly.
One common theme is survival. The OC often has to find ways to survive in the deadly games orchestrated by Monokuma. Another theme is mystery, as the OC tries to figure out Monokuma's true intentions and the secrets behind the whole situation.
In a human fanfiction, their relationship could become more complex. Since they are no longer just mascots in a game - like setting, they might develop a more nuanced friendship or rivalry. For example, if they are classmates, Monokuma could be jealous of Monomi's popularity among their peers, leading to a strained relationship.
One popular Danganronpa Monokuma and OC fanfiction is 'The New Student and Monokuma's Antics'. It has an interesting plot where the OC tries to outwit Monokuma in a series of deadly games. Another is 'OC's Encounter with Monokuma', which focuses on the psychological battles between the OC and the menacing bear.
Communication is key. In the fanfiction, they could have deep conversations about their dreams, fears, and past traumas. Laslow might share his experiences as a wandering mercenary, and Corrin could talk about her complex family situation. Through these exchanges, they would understand each other better and draw closer. Another aspect could be through acts of self - sacrifice. If one of them is in danger and the other risks their life to save them, it would strengthen their bond significantly.
Another way is through sacrifice. If Orihime sacrifices something important for the sake of an Espada, or vice versa, it can deepen their relationship. This act of selflessness can show the depth of their feelings for each other and be a turning point in their relationship within the fanfiction.
The relationship can be developed through shared experiences. For example, they could go on a joint mission to retrieve an important artifact. During this mission, they face various challenges together, which helps them bond. They might have to trust each other with their lives, and this deepens their connection.
By showing them having heart - to - heart conversations. For example, they could talk about their experiences growing up as demigods, their fears, and their hopes. This would deepen their connection.
By creating more shared experiences. For example, they could go on a journey together to find a special item or to help someone. During this journey, they would face challenges and have to rely on each other, which would strengthen their bond.
