I'm not sure about specific 'persona 5 ren hurt fanfiction' titles off the top of my head. But you can try searching on fanfiction websites like Archive of Our Own. They usually have a wide range of fanfictions related to Persona 5.
One great fanfiction could be about how Makoto, being older, takes Ren under her wing. She could help him navigate the complex world of the Metaverse. Maybe she teaches him some of her combat skills and strategies.
One common theme could be the struggle for identity. The OC in the Persona 5 universe might be facing challenges that make them question who they really are. Another theme could be the battle against the shadows, not just in the metaverse but also within themselves. And of course, friendship and betrayal are also often explored. For example, the OC might be betrayed by someone they thought was a friend, which leads to their 'hurt' state, and then they have to navigate how to deal with that while still trying to save the world.
A common theme is the mentorship aspect. Since Makoto is older, she often guides Ren. Another theme is the power of their combined abilities in the Metaverse. They can achieve great things together.
First, you need to develop your OC well. Give them a unique personality, backstory, and motivation. For example, if your OC is hurt because of a past trauma, explain what that trauma was and how it affects their actions in the Persona 5 world. Second, understand the Persona 5 lore. Incorporate elements like the metaverse, personas, and the Phantom Thieves' goals. Third, create a strong plot. Maybe your OC starts as an outsider but gets drawn into the Phantom Thieves' activities and has to deal with their own issues along the way.
Another storyline might involve the orange - haired girl getting into trouble in the real world. Ren has to use his wits and skills from the Metaverse to help her out. Maybe she's being framed for something and Ren has to prove her innocence. This would show their loyalty to one another and also introduce some mystery and intrigue.
When writing Ren and the orange - haired girl's relationship, create meaningful dialogues between them. Let their conversations reveal their feelings and thoughts. For example, Ren might share his fears about the Metaverse with her, and she could respond with words of encouragement. Also, show their body language when they're together, like Ren's slight blush when she gets close.
One interesting plot idea could be Ren traveling back in time to prevent the initial Metaverse incident. This would change the whole course of the story, and he'd have to deal with the consequences of altering such a major event. Maybe he'd face new enemies or form different relationships.
One common theme could be emotional pain. Since it's 'ren hurt', there might be a focus on Ren experiencing some form of emotional distress, like heartbreak or feelings of betrayal. Another theme could be self - discovery in the face of that hurt. Ren might be trying to figure out who he is and how to move forward after the difficult situation.
