Yes, the Nagatoro manga has ended. It might have left fans with a mix of emotions, but it provided a definitive conclusion to the tale that had been unfolding.
In yandere x reader fanfics, yanderes usually display intense emotions. Their love for the reader is not the normal kind; it's more of an obsessive love. They may have a dual personality where they can be extremely sweet and loving one moment, but if they feel threatened in their relationship with the reader, they can turn very dangerous and menacing.
Definitely not. 'Nagatoro' is a character from a series and creating sexual fanfic about her is disrespectful to the original work and its audience. It also promotes an unwholesome and inappropriate culture.
