The starting of the story was intriguing and there were a few moments which was pretty thought provoking, plus though the mc wasn't strong conventionally, I liked how he had his own strengths and his own morals but towards the end, it felt like there was a lot of stuff like concepts and theories being thrown in, and the role of the mc kind of diminished?
Like he still had a role to play in the fights, but there was so much shifting of scenes between the fights that it was pretty hard to determine what the characters actually needed to do and how they contribute to the scenarios unlike in the first part of the series. The same could be said about the reveal about the truth of their world and any relevation on what needs to be done.
To be frank I'm partially at fault for not fully understanding the story's ending since I was swapping between the fan translations in different languages (English, Malay to English via google translation, and finally Chinese) since the English translation wasn't complete for the manga unfortunately.
But honestly I think a big part of the reason why I felt like I didn't quite comprehend what the end of the story was trying to do was also because it was too rushed. I think it needed another season at least to pace the story correctly, because at the end, it felt like they were just moving to where the monsters were, and the origin of the monsters didn't feel explained at all?
If I could find the novel translations, I would probably give it a go just to see if it is any better, though that's if I can find it in the first place.
