While the manga was popular and enjoyed by fans, it's important to understand that anime adaptations are complex and depend on several factors:
* Popularity and Sales: While "Mysterious Girlfriend X" had its fanbase, its sales might not have been high enough to warrant an anime adaptation.
* Licensing and Production Costs: The rights to adapt the manga into an anime need to be secured, and production costs for animation can be high.
* Market Demand: Anime studios often assess the market demand for a specific series before greenlighting a project.
Therefore, it's currently unlikely that "Mysterious Girlfriend X" will be made into an anime. However, it's always possible that circumstances could change in the future, leading to a potential adaptation.
