This novel is one of the best novels I have read so far. It combines wonderful, well-described action scenes with a mysterious, dark, and gritty adventure that expands across multiple areas with their own cultures, rules, and environments that seem like their own little worlds...
(They are technically their own worlds, but that is explained much later in the story)
The first arc is one of the best in the novel because it has everything that the reader can expect throughout the rest of the novel: 1 A sense of misfortune and fear. 2 A gritty, dark world where monsters lurk around every corner and humans stab each other in the back given any opportunity. 3 A loner main character who is trying to find himself, find his purpose, change his fate, and to achieve that purpose with strength, but most importantly trying to survive.
My personal favorite part about the novel is the world building. The main character is written in a way where the reader experiences the mysteries of the world and its system in the same way, slowly piecing together the clues left behind to determine how everything plays a part in the main characters fate...and then watching the main character trying to find a way to change that fate. It's wonderfully written in this regard: Each scene is described in a way that allows the reader imagine the world with their own little twists on it.
As a fan of romance and romantic subplots in every piece of entertainment I read, I am disappointed with the romance in the novel. The official release site, Webnovel, have it tagged as romance (which is why I add3d the romance tag here when I first added the series to the site), but there is still no romance besides a couple of moments...even at chapter 1630 or so. I have a good feeling it is coming eventually, though, so I am enjoying the journey.
Anyway, if you are debating reading this for whatever reason, give it a try for at least the first arc. I promise the main character is a great guy who grows in both his humanity and his relationships. I didn't want to read it, at first, because I was under the impression the main character was a loser slave to the female main character, but he isn't.
He is a slave, but he doesn't like to be one, isn't treated as one, and he keeps up his attitude of wanting to be free throughout the novel.
Also, the sister tag in the categories just means that the main character has a sister who is important to the story and his character.
