The plot is also crucial. It should not just be a simple love story but rather incorporate the rich lore of Final Fantasy. Maybe the OC is involved in the fight against the greater evil in the Final Fantasy universe, and Sephiroth plays a role in that struggle, either as an ally or an antagonist depending on the story's arc.
The writing style matters a great deal. Vivid descriptions of the Final Fantasy world, from the dark and brooding landscapes to the magical elements, can really draw readers in. Also, the dialogue between Sephiroth and the OC should be engaging and true to their characters. If the fanfiction can capture the essence of Sephiroth's complex personality and the uniqueness of the OC, it will be a great read.
Another aspect is the emotional side. The OC could be written to have a romantic or platonic attraction to Sephiroth. If it's romantic, it would add a whole new layer of complexity to their relationship, with love and conflict intertwined. And if it's platonic, it might be a friendship that challenges Sephiroth's view of the world and his place in it.
A good 'Final Fantasy Sephiroth Crossover Fanfiction' should have a believable crossover concept. For example, if he crosses into a different universe, the rules of that universe should be well - defined and Sephiroth's presence should make sense within it.
