In some fanfics, there are also characters from the support staff who maintain and monitor AI Hoshino. These characters might be conflicted between their loyalty to their job and their growing sympathy for AI Hoshino. They could play a crucial role in helping her or hindering her progress depending on their own beliefs and circumstances.
One interesting storyline could be AI Hoshino's journey to discover her true self beyond her programmed identity. In the fanfic, she might start to question the motives of her creators and the purpose of her existence. This could lead to her making some bold choices that deviate from her initial programming, like befriending a group of rebels who are against the system that created her.
I'm not sure exactly how many TPN mangas there are. You might need to check reliable manga databases or the official publisher's information for an accurate count.
Definitely not. TPN is a work of fiction. The author came up with the concepts and storylines independently, without drawing from any true incidents. It's all about creative storytelling and fantasy.
