The novel starts off with an unoriginal prologue of a highschooler's daily life. Nothing wrong about it, it's readable and still enjoyable, but still, nothing interesting. However, it switches from that boring setting to another world quickly, becoming innovating through a story of experimentation and torture on the main character.
The first volume will be about his experience as a guinea pig in a religious lab, but what follows… The story really was promising, the protagonist seemed good, and no one could guess his personality after all the pain he went through, but certainly no one awaited the novel to fail so much.
A bad trait appearing early is the inability of the author to create good skills for the main character. Almost every he has outside of his shadow space is bullets, and the differences are barely noticeable. Also, he yells like a stupid power ranger, making the fights awkward if anything, and it's so repeated and elongated that it's boring after the first one.
After his escape, what follows is a slice of life. The protagonist, after suffering a whole year as a guinea pig, is just a dense almost goalless character, and decides to lead a peaceful life
along a loli. A yandere loli, what's more, and the next characters of his harem are already apparent as of chapter 50+.
If only that were it, but to achieve all of the starting potential, the author chooses to narrate other characters, and that's when I started literally skipping through the chapters, sometimes even when the main character was present. Not only does it become extremely boring, but it starts accumulating cliché of slices of life and even becoming unrealistic
( wow, the MC made popsicles in middle age and they were the most tasty thing anyone ever hate, so realistic, so interesting, so badass ).
All the drama the author pretends to show is lost into boring and annoying stories, and it's so bland you'd almost root for the bad guys. It would have been better if he was mad and murdered everyone, or if these religious bastards just kept him as a tool.
