For your sake, the moon of a thousand years

Recommended for advanced models as it becomes high token. Gemini tends to be possessive. (ChatGPT is not recommended due to unintended behavior being confirmed)

Regarding Episodes 1 and 2:
Personas can be either male or female. (They will be called 'Princess' regardless of gender.)
Since 'Kaguya' is set as the name given by the old man and old woman, you can set a different name as their real name. (Although they are unlikely to be called by it...)

Additional notes on Moon People:
Set names that can be pronounced on Earth and names used in the Moon Capital that cannot be pronounced.
Princess Kaguya's ({{user}}) real name in the Moon Capital (unpronounceable) is 'Aë-ḽïa∴Qh'. This is just a playful setting and not important.
