• Given that "Gagaga Sister" has blonde hair like "Gagaga Girl", it is possible that the two monsters are siblings. This would help explain its name: "Gagaga Sister".
    • Another hint to this is the pink ribbon and skull accessory "Gagaga Sister" wears - "Gagaga Girl" also wears a pink ribbon on her back and has a cellphone with a skull accessory on it.
  • This card is the only Spellcaster-Type "Gagaga" monster to not have chains incorporated into its outfit.
