Lady Okyanu, the High-Class Prostitute, is an NPC that you can Visit or randomly encounter when you Take a Walk. You can random encounter her at the Palace or Slums, raising your slave's Refinement (+1) and reducing Morality (-1).
If you Visit her and Refinement >= 25 or you live in the Mansion, she will be awarded +1 Charisma / +2 Refinement / +1 Conversation / +1 Trib/Strap-on (if a Lesbian Slave) / +1 Reputation (Conversation will increase even if it is at its limit).
To hear about the party, you will need Conversation at its limit, at which point she will say that there is a party in 3-4 days, and, on subsequent days, the Lady will inform you whether your slave meets the requirements needed to attend if you Visit her. These requirements are:
- is wearing a courtly or your slave's special dress
- owns at least 2 pieces of Jewelry
- Refinement >= 60
When the days are up and you meet the requirements, she will invite you to the party once you Visit the Lady. If you miss the deadline by not meeting the requirements or forgetting to Visit her, Lady Okyanu will say there is another party in 6-8 days. She will continue to give more chances until you are invited to the party and decline the invitation.
If you choose to attend the party, she will pick up your slave at night, so you cannot do any Night Actions that day. Attending the function raises the limit on Conversation. During the party, you can choose to do several things that will raise your Statistics. Note that if you want Courtesan Training or the Courtesan General Ending, you must choose to accompany Lady Okyanu.
In order for Lady Okyanu to offer courtesan training, you must accompany her when asked what you want to do during the High-Class Party. She will ask you if you want courtesan training. Choose yes and you can Visit her 3 more times for stat boosts:
- Refinement +2, Intelligence +2, Cleaning +1, Conversation +1, Blowjobs +1, Fucking +1, Lust +1, Reputation +1
- Charisma +2, Sensibility +4, Refinement +2, Cooking +1, Conversation +2, Lust +2
- Charisma +2, Sensibility +2, Refinement +4, Intelligence +2, Conversation +3
It is important to note the fact that the Bit Gag item subtracts 1 from Conversation every day, so if you want any slave to undergo this event you have to remove it and allow her to talk (in the Rules morning subsection)
