Who is Tails' girlfriend?

Excuse me, but I was wondering if you could clarify something for me. In the context we're discussing, who exactly is Tails' girlfriend? Is she a character from a specific comic book, anime, or movie series? Or is she a figure from the world of finance or cryptocurrency that I may not be familiar with? Could you perhaps provide a brief overview of her background and how she relates to Tails? I'm quite curious to learn more about this individual.
