3. Ves content
As mentioned previously, she appears after the 2nd Battle (her initial Arrival Scene can differ if you Submitted to Swan or not before it)
o progress through her Content (including her H-scenes), this is the order of doing it:
1. Get her Arrival scene
2. Talk with her, during the day, until she expresses her concern for her sect brothers (until you get the option for her normal , repeatable, dialogue options)
3. Pass the day, then find her in Swan's Room next day and talk with her
4. At night, enter Swan's Room and interact with Ves in her bed (H-Scene)
5. Next day, find her in Swan's Room and talk with her
6. At night, you'll automatically get her next H-scene
7. Next day, once again, speak with her in Swan's Room
8. At night, you can find her in front of the Exit gate of the area, and talking with her triggers another H-Scene, before she leaves, and enables her Individual content (including her own Area, her Fight and loss scenes)
If you don't finish her content up until her leaving before getting Karen's Inspection (before having the 3rd Fight with Swan), you will be locked out of her Individual content (as she remains on your side, as you defeat Swan&Crow)
Similarly, having all her content finished, but losing in the Twins fight of Karen's Inspection (no matter how you lose) only enables you to visit Ves and talk briefly with her in her new Area (but the actual content for her is locked, as you're already a Slave of Swan/Crow)
