Thanks for the response. When I was referring to the slave route I was referring to if there were other slaves/servant type(s) (class/hierarchy/etc. system) in the future planned that way the choice near the beginning would be for that kind of route in general. Will there be other slaves or just that character so it does not bloat up the harem list? As far as the Feral type of character I think they should still be somewhat wild-ish in were they live. Maybe they live with the MC but still roam around and are still confused as a beast at times. A personal inspiration for this idea comes from the mangaka "Takatuki Nato (Sokomono Suisou)." The type that actually talks in some way. Drawn in an Original way if you can or something that is easy for you but still unique.
Ah, I see. At least one more slave is solidly planned for the future, after that I'm not entirely sure. There will most likely be interactions between the slaves as well.
For a feral type character, I hadn't thought about it, but it does sound interesting. I'll have to take a look at that manga. Thanks for the suggestions!
