The main battle outfit has few customizations. Ai-deal has Skirt vs no-skirt. Underwear vs No-underwear, and strap vs strapless. The battle outfits color can change. There are ~5 "skin tones" to set: anime, luminous, black-tech leotard, and a few others.Since it's a 3D game, what kind of modifications can you make to the girl? Or is it set in stone?
So she has some customizations, but "not a lot" IMO, especially not for a 3d game like this. But "some level of customization" is better than none.
However, there are a large number of customizations in NTR and/or Vanilla sex-scenes.
* Traditional Underwear
* Battle outfit
* Casual 1 (similar to Battle outfit without the floating tech/mecha stuff around her).
* Casual 2 (Short-shorts and jacket)
* Swim 1 (Similar to Battle outfit but missing leggings and techy stuff)
* Swim 2
* Swim 3 (Bikini)
* Extra 1 (Prostitution outfit: Combination of Swim3 and Casual 2)
All of these costumes have enable/disable settings. Skirt is on/off on Battle outfit, Casual 1. Casual 2 and Underwear has no skirt option at all though. The NTR and Vanilla sex-scenes will match the outfit you give her. I'd say ~4 items to enable/disable on each one, even if these items (ex: skirt) are shared between Battle / Casual1... it still feels pretty fresh overall.
A universal configuration is Ai-deal's "Virtual Long-hair". She has holographic long-hair that you can turn on or off.
There's a second character you get for a temporary, story time. She has no customizations available but you get about 3 or 4 scenes. A major foe has a breakable costume if you perform the "Cluster Drain" on this foe, you actually rip her dress off, and she'll fight in her underwear for the rest of the fight. In her "final form", you'll be able to rip off her underwear too.
