Seriously speaking, What really happened is Nomura putted his Hgame waifu Aoyama Misao (since 1993=1997-4) knockoff: https://arch-img.b4k.dev/v/1747320995033.jpg
there as a placeholder (with a placeholder name) in a diagram which he made FOR FUN ("no one asked me to").

That thing also came back from recycle bin as they need a substitute while the genuine heroine became absent.
