So if you're avoiding any Netori what characters should we expect to never be an option to pursue just so we don't end up getting our hopes up for a certain character.
Also will you be gender-swapping or humanising (like Kyouhukou in Overlord H) any characters in the game?
It is not just a matter of being against NTR, Tione does not really feel that way for Bell either.
Even if I wrote her differently, her entire personality and tastes do not really align with Bell's, it would feel forced, and only to have another pair of big tits.
Tiona has a different body type, and she naturally fits with Bell. It is a good option to have overall.
I also do not plan to gender-swap any character as I believe that was a mistake in Overlord H and I do not wish to repeat it.
Anime like these have plenty of women already, with an existing fanbase which would rather have content with them than a random genderswap (granted some gender swaps like Jircniv are actually good, but rare.)
As for a list of characters, that is hard to answer as I do not know how long the game will last, it is still too early to say and it highly depends on the feedback I will be getting. Current plan is two seasons.
