There are quite a few "branch" (and ending) in the game. the best option is to learn where they are, create a save and explore every path.
i dont have played every path, i have done only two of them and see the cg of other route and endings in recollection room, because when u hit one ending, no matter what, a prompt pop up and let you choose to unlock all the gallery or not. useful if u dont whant bother too much to explore every route in the game.
btw for now we have;
the classic ntr done by the blond guy ally (kiss/heal him with the blonde girl to trigger the event's, but of course dont let her to be kidnapped if u whant to see this ending)
blonde girl kidnapped by the colored and bald villain (villain from the first game), done by thug enemy.
blonde girl kidnapped by the orc, obviously done by orc unit.
blonde girl kidnapped by the pope, dont know what church unit can kidnap, but i think is the holy knith with horse
if the pink girl is touched by a thug she will be sent to the turban guy, this can be done, at the same time, with one of the path above.
