That villain kill was kinda dumb. He did what he was supposed to do, so he can die now. While previously having zero trouble defending against that very same attack.
We also have no timeframe in which he accumulated those points. Even if he did outsource a lot of the work for it to ghostwriters and such, it still took time to prepare and spread on the internet.
I don't think it's a new character, but instead the Woman that was with the ML? She is famous for her needlework, attacked with a needle, knew that he would try to steal it and didn't like that thought.
How does one tag? She changed worlds, so no reincarnation or timetravel involved (she shouldn't even have died in her old world)
@FaleNxHunter doesn's seem to work?
So she is abused and he has trust issues, so I hope that they will start healing themselves with each other. He can teach her to be more independent and she that it's worth it to care for others.
