- Some fans have jokingly called Yinu's mother (who is not named) "Karen" after the stock internet alias, due to her questionable parental skills and Jerkass behavior.
- None of the members of 1010 are named, but the fandom has managed to give them names by deciphering the signatures seen in the game: Rin (white), Eloni (green), Zimelu (red), Haym (yellow), and Purl-hew (blue).
