I'm wounding whether I should put Uran in my story. I'm not to sure if I should because I don't think she would fit in this story at least for the most part. Because the story I'm doing is going to be dark and Astro in this fic is going to be more of a fighter than he has ever been but he's still going to have the big heart that he's always had. So I'm not sure if she'll fit in the story. If I am going to put her in it I'll have to put her in it near the end or in a spin off or sequel to the story, not really sure let me know what you guys think.
the term your looking for is Fraternal twins, a set of twins who are not identical and can be different sexes. wonder what Tenma thought when he heard the news about twins? then having a daughter thats like him, how do you guys think he'd react?
