Imo there is no proper way yet, the dev usually creates routes and split ways, for in the future just use one of them, for me it made sense to let the demon and succubi take over the church, as the demon wont interact with the girl and most importantly the succubus showed her despite for the demon, so probably we'll kill him and get his role, this is my headcanon, i just hope that we can corrupt her bodies also(in a non ntr route), my dream in this game is that we get more breast expansion/body modification, like we got with the princess(bigger dream) and that we get more opportunities to share casually the girls, like i mentioned in the previous post(smaller dream)
