I mean, the only way this *doesn't* get a happy ending is if it gets no ending at all. The overall mood of the game is pretty clear, and it's obviously meant to be happy and nice.
That being said, the ending is still *way* far out.
Most likely gonna have multiple endings, the main one is most likely Harem while the others based around charecters who already have alot of relationship, stuff like Mika, Petua, Kira, Kotone, Bella, and Beris etc, etc.
Plot twist: defeating the Demon Queen frfr causes all Monster girls to go back to being bloodthirsty beasts, instead of just thirsty beasts. Either you become Demon Lord and stand at her side, or the world plunges into a living hell.
