I don't what you mean by "standing". Maybe you mean their "way of thinking" that makes them act differently from other characters.
By standing I was referring to Asuna's position and status in her own universe, although not in a literal way but instead how we personally as an audience/player base judge her character.
We, human beings, judge things by comparing them to others.
Someone is rich, because there are poorer people.
Someone is tall, because there are those who are shorter than them.
Someone is a fat pig like Inoda, because not everyone is a miserable piece of trash like him.
Someone has a small penis like Kirito, because not everyone has a peanut size dick.
The fact that Asuna is a cheater and slut that thinks with her vagina gets cheapen the more women in her universe are all equally cheater and sluts.
Izuku might not be more heroic than his classmates but being a quarkless gaining a quark and training to be a hero does make almost unique in the world.
Funny enough, not even there Izuku is unique because All Might was also quirkless before getting All for One.
I guess what you want in this game would be only Asuna becoming a cheater. That would make her different from all the other woman and make Inoda seem more impressive because he is doing something no one else can do.
Think about this another way, breast sizes.
If you see any erotic anime or hentai game with various heroines, almost all of them make it so the some of the heroines have big breasts or some of the others have small breasts. This is because it would be boring if everyone was the same. (Also because they manage to market themselves to a broader market by appealing to more interests with varying heroines, but that's a whole other point.)
Another example of the importance of a contrast is dick size.
If everyone in a fictional world has a big dick, equal in size to the rest of the men in the world, then there is no feeling of superiority to come from the the random heroine talking about how the audience self-insert is large or thick.
. Of course that would mean all the other side characters like Liz and Suguha only getting involved in loving relationships which would make divide the community at the very least.
You know, funny thing you mentioned this, because there was no real need for Suguha to get raped and corrupted for her to get netorared. If instead of Hebishima being a piece of trash NTR cliche was some random character that fell for Suguha and managed to romance her out of her incestous obsession, we could still have gotten ntr content from her.
Just give the hypothetical character a huge dick and hentai God levels of stamina while having a kink for filming himself with his beloved girlfriend.
After all, it's not like liking sex makes you a slut. It's still possible to get amazing sex scenes and debauched scenarios between a loving couple, Kirito getting somewhat netorared in the process could have been a bonus.
