First, decide what kind of non - human Ash will be. If he's an alien, think about his home planet's characteristics and how they affect his behavior. For example, if his planet has a higher gravity, he might be stronger than normal humans. Then, create a plot. Maybe he's trying to hide his true identity while falling in love with a human. Next, develop his relationships with other characters. If he's a magical being, how do other humans react to his powers? Remember to keep the story engaging and unique.
To write 'ash isnt human fanfiction', start by brainstorming the type of non - human entity Ash could be. It could be a mythical creature like a centaur or a mermaid - like being but in a more human - looking form. Then, consider the setting. Is it a modern - day city or a fantasy world? For the plot, you could have Ash's non - human nature revealed gradually. As for the characters, make sure their reactions to Ash are believable. For instance, if Ash is a demon in disguise, some characters might be immediately distrustful while others are naively attracted to him. You also need to think about the conflict in the story, whether it's internal (Ash's struggle with his non - human identity) or external (others trying to expose him).
