Albino girl wants to conquer the world! Please stay out of the way, Su!
If it blocks the road, haha!
Kill you~
The Mary Sues in this article are not exactly the Mary Sues who are dying of NC.
Most of them are the kind of abominable time-travelers who, after time-traveling, use their previous skills, disrespect the fruits of other people's labor, and use what they learned in their previous lives to show off their power. Most are not too NC.
Eliminating Mary Sue actually allows them to return to their original world [willingly].
So it's more difficult.
