Well, for writing a great Touhou male OC harem fanfic, you need to focus on the male OC's character arc. He should grow and change throughout the story. As for the harem, think about how each Touhou character fits into the group. They all have different personalities and roles in Gensokyo. For instance, you could have a shy Touhou character who is initially hesitant to be part of the harem but warms up over time. You also need to create a believable world. Since it's set in Gensokyo, research the existing lore. Use descriptive language to bring the settings and characters to life. And most importantly, let the chemistry between the male OC and the female characters drive the story forward, rather than just relying on the harem concept alone.
