To write a compelling OC in relation to Mitsuru, first, give the OC a distinct personality. For example, if Mitsuru is more reserved and serious, the OC could be outgoing and humorous to create an interesting dynamic. Also, give the OC a unique backstory. Maybe they grew up in a different country or had a special encounter with a Persona at a young age that shaped their abilities. Their goals should also be clear, whether it's to become a strong Persona user like Mitsuru or to find a way to end the Dark Hour once and for all.
One good storyline could be an OC who is a new transfer student at Gekkoukan High School and quickly catches Mitsuru's attention due to their unique abilities in the Dark Hour. The OC could initially be a bit of an outcast but gradually forms a strong bond with Mitsuru as they work together to face Shadows. Another idea is a fanfiction where the OC has a special connection to Mitsuru's family history, perhaps uncovering secrets that were long forgotten and helping Mitsuru come to terms with her heritage. There could also be a storyline where the OC is from a rival organization but ends up falling for Mitsuru and has to choose between loyalty to their group and their new - found feelings.
In some fanfiction, there might be a scenario where they get into an argument over a decision regarding the SEES group. Maybe Mitsuru wants to take a more cautious approach while Makoto is eager to be more aggressive. But through this conflict, they learn to compromise and strengthen their bond as leaders of the group.
Their relationship often develops through shared battles. As they fight side by side against the Shadows in Tartarus, they start to trust each other more. They rely on each other's strengths, like Makoto's physical combat abilities and Mitsuru's strategic thinking.
