So she is always going to be the main adult content? Ughhh seriously?
Feel free to direct away, though I suspect I'll have played them already.
Personally, I will say this, it seems kinda pointless to even bother making any other woman alluring, or even having them, if this is 'Annoying Alt Glasses Girl Simulator 1.0' tbh. If that is the case, Gianna could be Gino, the cool, dashing, Italian Nobleman with a feathered bicocket and two swords.. if only one made of metal. Yuki could be a Goblin kid called Fungus, playing at being the best Denis the Menace he can be, and it would not REALLY impact the story. Ravenna could be a blobfish-like alien called something impossible to pronounce without using your colon as well, and it would work for her narrative, just not her pointless teasing.
Every other woman, the Elf servant, the Elf hotty in the woods mistaken for a ghost, the Shar chick, the witches, they could all be doughy, ugly, stinky, painful to look at, wenches you know have red bumpies and will give a man pizzle-rot even just sharing the same air with them... and it would not make one iota difference to the story over all. Might mean no tease scenes, but who wants them, if they cannot have more?
In fact, I would have actually appreciated that, it would have made Natasha actually hold a tiny tiny bit of value in the game..... though I likely would still have gone gay for our Gino over touching her had I the chance :P But at least it being a love story, would be OK. But being a love story that teases at being a Harem? Nah, kinda not coll yo. very not.
Just saying.
