It genuinely felt uncomfortable to watch this.
To be fair, that was a major part of the Dolce birthday events in DOAXVV, so that bit wasn't unprecedented. Even characters who definitely weren't the submissive types engaged in that kind of action.
And for what it's worth, at least the True Color event for Fiona has her stepping up her game a bit. She's still a little bit better than the recent Disney Princess fare where the creators of them seem to mistake outright misandry for strength.
Also, to Jade in Chains, I'm pretty sure that's supposed to be an Ice Cream Sundae.
Either way regarding Fiona, one thing I definitely hope for regarding Prism is giving an ACTUAL nationality for the add-on girls, especially the non-Japanese ones like Fiona. I really got irritated at how DOAXVV seemed to lack any nationality entries, even though the Xtreme series overall made sure to include nationality sections. At least the mainline ones had their nationalities confirmed with past games, and Misaki and Tamaki had her nationality directly confirmed in Xtreme 3 Scarlet and DOA6 respectively. The rest don't have the same luck. The closest we have to a confirmed nationality among the non-Japanese girl add-ons is Patty, and that's only because it's made clear she hailed from the South Pacific due to hailing from one of the islands neighboring the main setting.
