I'm giving this game five stars because Lobelia's route clicked with my brain so much by the end, I haven't stopped thinking about it for almost a year. I like Lobelia so much that it took me six months before I was willing to play the Light route. The two stories are unrelated. The Darkness route focuses entirely on the relationship between the sorcerer Lucil and Lobelia, a demon to whom he is contracted. From the point where you make the final choice, on auto play, the true ending plays out for two hours. Keep watching past the credits! The Light route is plottier and the romance very sweet. No surprises really, just a gentle little slow burn. I originally picked up the game because Manaka Sawa voices Lobelia, but I stuck with it for the characters. Lucil is a little irritating but eventually grew on me. And the classical music is lovely! If you need to avoid it, be aware there is noncon in both routes.
The game is very beautiful, if you just play the angel, Flow, route. Totally skip the other guy, yeah, he shares VA with Clear from DmmD, but thats it, Lobelias route is full of meaningless rape, nothing worth it.
