I'm not sure who Nikki Yovino is just based on this title. She could be the author of the story, in which case she might be a writer or storyteller. She might be writing from her own experiences or from her imagination.
A 'pokemon mira fanfic' could be about a fan - created story within the Pokemon universe. It might involve new adventures of Pokemon characters, unique storylines that deviate from the official Pokemon plot, and could introduce original characters or concepts related to Pokemon. For example, it could be a story about a trainer's journey in a region not seen in the main games, with new Pokemon species or forms.
I do enjoy them. Her storytelling style is captivating, and the characters are well-developed. Also, the themes she explores are quite interesting and relatable.
It's hard to say for sure. Some of the stories might be based on real events, but they could also be exaggerated or fictionalized for entertainment purposes.
There doesn't seem to be. Usually, if there was a famous ghost story related to her, it would be more widely talked about. Given her presence in the entertainment industry, any such story would likely have some level of popularity, but there's no evidence of one.
I'm sorry, I don't know the specific 'Mira Erda Life Story' as it's not a widely known common story to me. Maybe it's a personal or a very specific story within a certain community.
