I think the story confused me at the beginning, Lucy the sister is also a futa or not? I'm going to say no, but I'm not sure.
This is subjective but I preferred Mia with black hair, a pity, some doubts to see if I'm not confused, then the Futas have magical powers to control the mind ? it also seems that you have enhanced physical abilities or may be a lot of training, it gives me some pity that the Futas in this world are almost extinct, I guess we will not see a revolution for the moment.
Although interesting the Sub route is not for me, for the simple fact that we are going to hell, and if so it's better to do it ourselves instead of someone else, so I'll take a seat next to you Mia.
