Long ago, when tentacled creatures appeared in the city, it became public knowledge that some humans had these creatures as ancestors.
People called them “Anothers” and shunned them, believing they had been lurking in the shadows of history. However, since Anothers were indistinguishable from humans and impossible to identify, there was no open conflict; instead, their presence was met with latent loathing and fear.
