This entire story seems pointless. None of this really needed to happen, no one of any real "value" in this story dies, none of the characters are affected by any of the terrible events that happen in the end, and none of the characters besides Kazami and Koto have any real "deep dives" (if you could call this deep) into their motives. And even after their motives are revealed it doesn't really clear up the reasons as to why the plot unfolded in such a way. It just doesn't make sense.
