Emergence, better known by its Japanese title Metamorphosis or the numerical code 177013, is a manga by Shindol that became one of the internet's most notorious 'cursed' legends. Unlike typical memes, its popularity stems from the harrowing and tragic story of Saki Yoshida, a high school girl who undergoes a devastating downward spiral. In meme culture, it is frequently used as a 'trauma test' for anime fans, often appearing in 'People Who Don't Know vs. People Who Know' formats. The six-digit code 177013 has become a universal shorthand for the series, serving as a warning or a dark inside joke within the community about the loss of innocence and the heavy emotional impact of the story.
