One common plotline could be the OC being a new addition to Toman and catching Sano Manjiro's eye. Maybe they start off as friends, helping each other out in gang fights or dealing with the problems within the gang world. Another could be a more romantic plot where the OC has some sort of special ability or knowledge that Manjiro finds fascinating, leading to a deeper connection between them.
Involve the OC in the world of Sano Manjiro in a natural way. Don't just have her appear out of nowhere. For instance, if she's a new student at their school, show how she gradually gets to know the members of Toman. Let her have her own relationships with other characters besides Manjiro. This way, she becomes a more integral part of the story and seems more believable.
I'm not sure. This seems like an inappropriate or specialized topic that I'm not familiar with.
Often, the OC will have a troubled past that Alex helps them overcome. This could involve the OC being on the run from something or having lost someone dear to them. In some fanfictions, the OC is from another planet or dimension and Alex has to help them adjust to life on Earth. This creates a lot of opportunities for character growth and relationship building between them.
Well, a typical plotline might involve the OC's confusion upon reincarnation as Loki. They could find themselves in the middle of Asgardian politics, not understanding all the rules and power plays. Some stories may have the OC using their modern - world knowledge to outwit Loki's foes. And then there's the emotional side, like dealing with Loki's complex relationships, such as with Odin. The OC might try to mend those broken relationships in a different way than Loki would have.
One common plotline is the OC joining Nick in his detective work. They solve mysteries together around Zootopia, facing various obstacles and villains along the way.
One common plotline is the OC being drawn into Tom Riddle's world against her will. Maybe she stumbles upon his secrets and he then becomes possessive to keep her quiet. Another is a more romantic - yet still possessive - relationship where Riddle sees the OC as his and tries to isolate her from others. A third could be the OC initially being charmed by Riddle's charisma, not realizing his possessive nature until it's too late.
One common plotline is the OC being a new student at the DWMA (Death Weapon Meister Academy). Blair then takes an interest in this new and unique character. They might start off as strangers, but as the story progresses, they form a bond. For instance, the OC could be targeted by an evil force, and Blair decides to protect them.
Another plotline could be the OC being in danger, and Jack Frost having to rescue them. This could be because the OC has a special power that some evil force wants to steal or because the OC has accidentally stumbled into a dangerous situation while exploring the magical world. Jack Frost then uses his ice powers and his wits to save the OC and keep them safe.
Often, there's a plotline where the OC is a servant or a low - born character who rises to prominence and has to deal with the politics of Tywin Lannister and the Starks. They might be caught in a web of lies and intrigue as they try to serve both sides without getting killed. Also, a plotline could involve an OC as a mage or a seer who foresees the destruction that the feud between the two houses will bring and tries to stop it.
