I can copy the beautiful girl

For every person that appears before me, I can choose whether to copy all of their abilities onto myself, or to directly copy the entire person and make the copy a servant that absolutely obeys me - this is the ability I possess.
I have always chosen the first type of copying. After all, I have no interest in servants in reality.
Until one day, I suddenly discovered that I had another ability, which was that I could travel into a fantasy world through computers and mobile phones.
