I like dark stories (when they're done well, because some of them sound like a clumsy Zack Snyder script) and I really enjoyed seeing the conclusions to Emma's arcs, especially her solo route, which is already very dark, by the way, and which creates thought-provoking narratives as it also brings out some dark facets of Hera and the motivations behind her actions.
I'm curious how the story will go from here, after the revelation that the MC took part in the same experiments as Moon and how this involves the MC's father and Hera. Anyway, what happens will only depend on NiiChan and so far he hasn't let me down.
