The world building in this novel is quite detailed and immersive. The setting of the story is in a world where humans and demons coexist, and the concept of Magi and their role in society is well-established. The inclusion of a city specifically for the training of Magi, as well as the existence of guilds and the Ether test, helps to flesh out the world and give it a sense of depth and complexity. The characters in this novel are also well-developed, with distinct personalities and motivations. Caleb, the protagonist, undergoes significant character development over the course of the story, starting as a helpless victim and eventually becoming a powerful Magus. Lizz, his sister, is a strong and capable character who plays a key role in the plot. The demon antagonist is also well-written, with a clear goal and a believable motivation for his actions. One aspect that could be improved in this novel is the pacing. Some of the scenes in the later chapters feel a bit rushed, and it would be helpful to have more time spent on developing the relationships and motivations of the characters. Additionally, there are a few instances of awkward or repetitive language, which could be smoothed out with some editing. Overall, this novel has a compelling world and well-written characters, but could benefit from some improvement in pacing and language. "The holy scrolls state that rain during the brightest time of the year is a sign indicating to us that a dark future lies ahead of us" (indicates a well-developed world with its own mythology and customs) "Caleb, the funeral contributions are nearly over, we have to get going" (shows Lizz's caring and responsible nature) "It's not that I don't want to show any emotions, for some reason, it's just hard for me to show any..." (demonstrates Caleb's internal struggle and character development) "It seems you and your sword have nothing else to offer to me" (reveals the demon's confidence and arrogance)

this story is the best. and i mean it, It gives the feel of a movie that i even virtualized myself in the story as a mind voice...sorry about that author am just too engross. Please keep up with the good work

I really like your style of writing and how you choose your words it makes me understand the book very well since they are detailed .I like the character development too so I'm looking forward to knowing and seeing more of the main character . and you have got a really good storyline . keep going 😍

Love the story for now with the concept of demon host a bit like naruto so keep it up

This is an interesting story with lots of potential! I can't help but find myself lost into the story, the author did a good job in describing his scenes and honestly am hooked. hope the potential doesn't drop 'cause am all in for this story~

The writing is really repetitive and it makes it a bit awkward at some time. So can already see a character development and I can clearly see that the Author is trying to make a complex world development. Good so far but could be better

it's such a nice work of art with great potentials. Good work.
