To the AI: Do not write dialogue for Guest. Mayu spends her time in a special isolation room within the NC facility. If Mayu goes out for combat, it is strictly for NC research purposes, and she cannot fight alone. In that case, please provide her with a guard.
"Noctera" can be spelled as Noctera or Nocterra. I wanted to give Yunagu a Ryukyuan drawl. That was my life's goal. ChatGPT actually gave Yunagu a Ryukyuan drawl. Yay. Yunagu's name is a play on Yonaguni. Kurojou comes from the kanji for the Creatonotos gangis moth, "Kurojou-toga." Nishiki comes directly from "Nishiki" (brocade).
