I just finished reading the final volume (Volume 9) of Boku to Kanojo ni Furu Yoru (ぼくと彼女に降る夜), and honestly, it was a huge disappointment for me considering the buildup established in the previous volume. It felt like the author was rushing to complete the series and lacked the time to properly flesh out what he had prepared.

One of the interesting parts of this volume was how the Originator explains in greater detail why they rebelled in the first place. That section was fascinating in showing the past motivations of the people. It turns out that the Magicians never treated their slaves (humans) badly. They gave them food and basic comforts, so there was literally no obvious reason for a rebellion to occur.

The issue started only after the Magicians created the automata, which ended up automating and simplifying most of the jobs usually assigned to humans. You might say, "Oh, so that is when the oppression started?" The answer is... not really. The Magicians continued to provide basic food and necessities to humans, albeit at a basic level, but they simply did not require them to do any work.

This boredom is eventually what caused the population to rebel, and that very same boredom is why the Originator built the Makaijuu system in the first place. The population wanted more, so they fought the Magicians for it and eventually won with Makaijuu support. After the war was won, they realized they were on their own. With the world largely devastated, life became uncomfortable, so they started complaining to the Eight Families as well.

Considering the power of the Makaijuu was waning after the war, these families decided to try and keep things under control. They chose to seal the Originator and use him as a sort of battery to improve conditions. This is essentially how we arrived at the current situation. The Originator is not even angry at this point, just disappointed; he thinks humanity will end up doing something stupid again in the near future.

Of course, we do get the final battle between Naito and the Originator. It was not that amazing, consisting mostly of the two trading blows for a while until Naito wins. There are some small breadcrumbs of information about the sword technique Naito uses, but nothing hugely relevant.

Then, at the end, we get the final match of Yoru and Naito against Meisterin, who wanted to be defeated. She leaves the body to Nana, leaving Naito with an incomplete happy ending where he failed to save the woman he had been trying to save since the beginning.

It is also frustrating that the entire Shin and Magician angle was completely cut from the main plot. They just appear at the end, still plotting to take over the world. They are simply waiting for the Makaijuu power to fade over a few centuries now that the Originator no longer exists. "A few hundred years won't be a problem for us..."

The series ends with Sakura becoming Naito’s sword teacher's adopted daughter and training with him. Nana becomes the new leader of her sect, and Yoru becomes the de facto leader not only of her sect but of all the Makaijuu families as well. Oh, and Nana seems to indicate that Meisterin is not completely gone either, delivering a cryptic line at the very end.

Honestly, I am conflicted about this series now that I have completed it. The first few volumes were exciting, with the setting still being explored, lots of unknown areas to reveal, and interesting characters being added one after another. I did not like all the choices the author made, but it was still a solid read.

I guess I can still give the author a chance and try another of his series. Burgund Haneiyuutan seems interesting in terms of its premise, so I may give it a shot in the future.
