Girls
Private Outfit is what the girls wear when not in matches, namely on the home screen. You can also change their hairstyle and tan level when – say it with me – you unlock the ability to. I’ll explain more on this section in a moment.
Profile is mainly just some interesting facts about the girls. What you are likely to be interested in is the ‘Level Up Rewards’ tab which details exactly what you receive when a girl reaches a certain level.
Gifts is where you can give stuff to the girls.
The stuff you find in the Normal tab gives xp when gifted, so save them for every time you unlock a new girl for that sweet Owner xp boost. Some girls like certain gifts more, and you can get up to 3x xp for giving them their favourite food/drink. A full list is available over at /r/DOAXVenusVacation.
Special is mainly posecards. You can unlock posecards in the event store, and each card teaches the girls a certain pose they can then perform in Shoot mode and the Owner room when that feature shows up. Posecards are one use items, so you need one for each girl. Happy grinding.
Swimsuit adds that swimsuit to the girl’s private collection, which allows them to wear it as a Private Outfit.
Here is a confusing bit that will probably confuse the hell out of you. Whenever you get any swimsuit, you get two versions of it, a ‘match version’ and a ‘cosmetic version’. The match version is the one you see in the Outfit screen, the cosmetic the one you see in the Girl screen. Let’s say you want every girl to have the ‘Popcorn’ swimsuit equipped as their private outfit. To do so, you will need to obtain that many number of ‘Popcorn’ swimsuits and individually gift them to each of the girls. Assuming you have all 10 girls and 10 sets of the swimsuit, by the time you have gifted them all you will have 10 Popcorn swimsuits in the Outfit tab, and 0 in the Girls tab.
Note that most SR and SSR swimsuits are character specific, and are added to their private collection immediately. However, SR swimsuits that you obtained before unlocking the girl for will have to be gifted manually.
Skin Care modifies the jiggle physics. Namely, they make certain body parts softer/harder depending on your preferences.
THE ABILITY TO MAKE STUFF SOFTER/HARDER IS NOT SOMETHING YOU CAN DO ON A WHIM. THE ONLY WAY TO DO SO IS THROUGH AN IN-GAME EVENT THAT HAPPENS EVERY 2-3 MONTHS ON AVERAGE, AND I HAVE NO IDEA WHEN IT WILL HAPPEN. STOP ASKING.
Granted, nobody asked me yet, but that’s an advance notice.
Lessons are unlocked as you get more girls, with 3 being required for the first room. I cannot remember off the top of my head the number you need for the rest, but don’t worry too much about it. There is a max of 3 rooms which cost 5,000, 50,000 and 500,000 Zack coins to unlock respectively.
The main selling point of this is that you can send up to 3 girls to train for a certain duration of time, up to 20 hours. The time continues to count down even when you’re not logged in, and the xp gain is a flat 5xp/10 minutes. Leaving them to train for the max of 20 hours gives you 600xp. It’s not exactly the best way to train, so don’t be in a rush to unlock all the rooms. The type of training you do doesn’t matter, since all it affects is the type of upgrade crystals you get when the timer hits 0. There is also a small chance the girls can return with a FP Refill Bottle, which is pretty great.
Note that no matter the duration, the girls will always either return with 2 or 5 crystals. If you’re looking to maximise gains, set them to train for 10 minutes, which will greatly increase the number of crystals you can get. However, they will only ever bring back small/medium sized crystals, so it is not as efficient nor as sane as it sounds.
Change Partner changes the girl on the home screen. That’s it.
