Would be nice if the game had a shota character too for that flavor of NTR but I dont think thats happening.
Very excited for this game, I hope that there is not too much more wait for its release.
My opinion on this:
It won't happen.
This game is an RPG, the player will tend to identify with the main character, so the dev can't make the MC a shota without taking the risk of losing part of the fan base.
This leaves two options:
either create an "evil" shota to steal the player's girls, but there are already too many rivals (and replacing one this late doesn't seem worth it),
or create a "victim" shota (I'd like to have the possibility of being a bad guy honestly), but this author is more on the netorare side of the NTR genre, so netori is most likely a no-go for him.
